Answer:

Gravitation Class 10 Maharashtra Board Question 2.
Answer the following questions.
(a) What is the difference between mass and weight of an object? Will the mass and weight of an object on the earth be the same as their values on Mars? Why?
Answer:
The mass of an object is the amount of matter present in it. It is same everywhere in the Universe and is never zero. It is a scalar quantity and its SI unit is kg. The weight of an object is the force with which the earth (or any other planet/ moon/star) attracts it. It is directed towards the centre of the earth. The weight of an object is different at different places on the earth. It is zero at the earth’s centre. It is a vector quantity and its SI unit is the newton (N). The magnitude of weight = mg.

The mass of an object will be the same on the earth and Mars, but the weight will not be the same because the value of g on Mars is different from that on the earth.

(b) what are (i) free fall, (ii) acceleration due to gravity (iii) escape velocity (iv) centripetal force?
Answer:
(i) Free fall:
Whenever an object moves under the influence of the force of gravity alone, it is said to be falling freely.

(ii) Acceleration due to gravity:
The acceleration produced in a body due to the gravitational force of the earth is called the acceleration due to gravity.
[Note: On the earth’s surface, the value of the acceleration due to gravity is almost uniform. If a body falls from a low altitude, the value of the acceleration due to gravity is almost the same.]

(iii) Escape velocity:
When a body is thrown vertically upward from the surface of the earth, the minimum initial velocity of the body for which the body is able to overcome the downward pull by the earth and can escape the earth forever is called the escape velocity.

(iv) Centripetal force:
In uniform circular motion of a body, the force acting on the body is directed towards the centre of the circle. This force is called centripetal force.

(c) Write the three laws given by Kepler. How did they help Newton to arrive at the inverse square law of gravity?
Kepler’s first law :
The orbit of a planet is an ellipse with the Sun at one of the foci.

Figure 1.5 shows the elliptical orbit of a planet revolving around the Sun (S).

Kepler’s second law :
The line joining the planet and the Sun sweeps equal areas in equal intervals of time.
A → B, C → D and E → F are the displacements of the planet in equal intervals of time.
The straight lines AS, CS and ES sweep equal areas in equal intervals of time.
Area ASB = area CSD = area ESF.

Kepler’s third law :
The square of the period of revolution of a planet around the Sun is directly proportional to the cube of the mean distance of the planet from the Sun.
Thus, if r is the average distance of the planet from the Sun and T is its period of revolution, then,
T² ∝ r², i.e., \(\frac{T^{2}}{r^{3}}\) = constant = K

For simplicity, we shall assume the orbit to be a circle.

In Fig. 1.6,
S denotes the position of the Sun, P denotes the position of a planet at a given instant and r denotes the radius of the orbit (= the distance of the planet from the Sun). Here, the speed of the planet is uniform.

If m is the mass of the planet, the centripetal force exerted on the planet by the Sun (= gravitational force),

According to Kepler’s third law,

Thus, F ∝ \(\frac{1}{r^{2}}\) as \(\frac{4 \pi^{2} m}{K}\) is constant in a particular case.

(d) A stone thrown vertically upwards with initial velocity u reaches a height ‘h’ before coming down. Show that the time taken to go up is same as the time taken to come down.
Answer:

We have, v = u + at …..(1)
and s = ut + \(\frac{1}{2}\) at² …..(2)
∴ s = (v – at) t + \(\frac{1}{2}\) at²
= vt – at² + \(\frac{1}{2}\) at²
∴ s = vt – \(\frac{1}{2}\) at² …..(3)
As the stone moves upward from A → B,
s = AB = h, t = t₁,
a = -g (retardation),
u = u and v = 0
∴ From Eq. (3), h = 0 – \(\frac{1}{2}\) (-g)t₁²
∴ h = \(\frac{1}{2}\)gt₁² …..(4)
As the stone moves downward from B → A,
t = t₂, u = 0, s = h and a = g
∴ from Eq. (2), h = \(\frac{1}{2}\) gt² …..(5)
From Eqs. (4) and (5), t₁² = t₂²
∴ t₁ = t₂ (∵ t₁ and t₂ are positive)

(e) If the value of g suddenly becomes twice its value, it will become two times more difficult to pull a heavy object along the floor. Why?
Answer:
To pull an object along the floor, it is necessary to do work against the force of friction between the object and the surface of the floor. This force of friction is proportional to the weight, mg, of the object. If the value of g becomes twice its value, the weight of the object and hence the force of friction will become double. Therefore, it will become two times more difficult to pull a heavy object along the floor.

10th Gravitation Chapter Exercise Question 3.
Explain why the value of g is zero at the centre of the earth.
The value of g changes while going deep inside the earth. It goes on decreasing as we go from the earth’s surface towards the earth’s centre.

We shall treat the earth as a sphere of uniform density. If we consider a particle of mass m at point P at a distance (R – d) from the earth’s centre, where R is the radius of the earth and d is the depth below the earth’s surface, the gravitational force on the particle due to the earth is

F = \(\frac{G m M^{\prime}}{(R-d)^{2}}\), where ‘M’ is the mass of the sphere of radius (R – d).

because the outer spherical shell is not effective (Fig. 1.10). In this case, the acceleration due to gravity is

where M is the mass of the earth. Thus, g decreases as d increases. It is less than that at the earth’s surface (\(\frac{G M}{R^{2}}\)) At the earth’s centre, d = R
∴ g = 0.

[Note : The formulae given in the answer are not given in the textbook. The formula density = \(\frac{\text { mass }}{\text { volume }}\) is used to find M’.]

Std 10 Science Chapter 1 Gravitation Question Answer Question 4.
Let the period of revolution of a planet at a distance R from a star be T. Prove that if it was at a distance of 2R from the star, its period of revolution will be \(\sqrt{8} T\).
Answer:
T= \(\frac{2 \pi}{\sqrt{G M}} \quad r^{3 / 2}\), where T = period of revolution of a planet around the Sun, M = mass of the Sun, G = gravitational constant and r = radius of the orbit assumed to be circular = distance of the planet from the Sun.
For r = R, T =T₁.

Class 10 Science 1 Chapter 1 Gravitation Question 5.
Solve the following examples.
(a) An object takes 5 s to reach the ground from a height of 5 m on a planet. What is the value of g on the planet?
Solution:
Data: u = 0 m/s, s = 5m, t = 5s, g = ?

(b) The radius of planet A is half the radius of planet B. If the mass of A is M_A, what must be the mass of B so that the value of g on B is half that of its value on A?  (Practice Activity Sheet – 4)
Solution:
Data : R_A = R_B/2, gB = \(\frac{1}{2}\) g_A, M_B = ?

(c) The mass and weight of an object on the earth are 5 kg and 49 N respectively. What will be their values on the moon? Assume that the acceleration due to gravity on the moon is l/6th of that on the earth.
Solution:
Data: m = 5 kg, W = 49 N,
gM = \(\frac{g_{E}}{6}\),m (on the moon) = ?, W(on the moon) = ?
(i) The mass of the object on the moon = the mass of the object on the earth = 5 kg
(ii) W = mg

(weight of the object on the moon).

(d) An object thrown vertically upwards reaches a height of 500 m. what was its initial velocity? How long will the object take to come back to the earth? Assume g = 10 m/s²
Solution:
100 mn/s and 20 s

(e) A ball falls off a table and reaches the ground in 1 s. Assuming g = 10 m/s², calculate its speed on reaching the ground and the height of the table.
Solution:
Data: t = 1s, g = 10 m/s², u = 0 m/s,
s = ?, v = ?
(i) s = ut + \(\frac{1}{2}\)gt²
= \(\frac{1}{2}\)gt² for u = 0 m/s
∴ s = \(\frac{1}{2}\) × 10 m/s² × (1s)²
=5 m
∴ The height of the table = 5 m.

(ii) v = u +at = u + gt
= 0 m/s + 10 m/s² × 1 s
= 10m/s
∴ The velocity of the ball on reaching the ground = 10 m/s.

(f) The masses of the earth and moon are 6 × 10²⁴ kg and 7.4 × 10²² kg, respectively. The distance between them is 3.84 × 10⁵ km. Calculate the gravitational force of attraction between the two. Use G = 6.7 × 10^-11 N.m² kg^-2.
Solution:
Data : m₁ = 6 × 10²⁴ kg,
m₂ = 7.4 × 10²² kg,
r = 3.84 × 10⁵ km = 3.84 × 10⁸ m,
G = 6.7 × 10^-11 N.m² kg^-2, F = ?

This is (the magnitude of) the gravitational force between the earth and the moon.

(g) The mass of the earth is 6 × 10²⁴ kg. The distance between the earth and the Sun is 1.5 × 10¹¹ m. If the gravitational force between the two is 3.5 × 10²² N, what is the mass of the Sun? (Use G = 6.7 × 10^-11 N.m² kg^-2)
Solution:
Data : m₁ = 6 × 10²⁴ kg,
r = 1.5 × 10¹¹ m, F = 3.5 × 10²² N,
G = 6.7 × 10^-11 N.m²kg^-2, m₂ = ?

= 1.96 × 10³⁰ kg (mass of the sun)

Gravitation Class 10 Exercise Answers Project:
Take weights of five of your friends. Find out what their weights will be on the moon and the Mars.
Answer:
Help: The weight of a body
(i) On the earth. W₁ = mg₁
(ii) on the moon, W₂ = mg₂
(iii) on Mars, W₃ = mg₃
∴ W₂ = W₁ × \(\frac{g_{2}}{g_{1}}\) and W₃ = W₁ × \(\frac{g_{3}}{g_{1}}\)
Now, g₁ = 9.81 m/s², g₂ = 1.67 m/s² and g₃ = 3.72 m/s²
If W₁ = 500 N,
W₂ = 500 × \(\frac{1.67}{9.81}\)N = 85.12N(approx.)
and W₃ = 500 × \(\frac{3.72}{9.81}\)N = 189.6 N (approx.)

10th Class Science Part 1 Chapter 1 Gravitation Exercise Question 1.
What are the effects of a force acting on an object? (Note: a body ≡ an object)
Answer:

• A force can set a body in motion. For example, if a ball at rest on the floor is pushed, it rolls on the floor.
• A force can stop a moving body. For example, a moving bicycle can be brought to rest by application of brakes.
• A force acting on a body can change the speed of the body. For example, when brakes are applied to a moving bicycle, its speed decreases due to the friction between the brake shoes and the rim of the tire.
• A force can change the direction of motion of the body. For example, in a uniform circular motion of a body, the direction of motion of the body keeps on changing due to the applied force.
• A force can change the speed as well as the direction of motion of the body. For example, when a ball bowled by a bowler is hit by a batsman, there occurs a*change in the speed as well as the direction of motion of the ball.
• A force can change the shape and size of the body on which it acts. For example, when a rubber ball is pressed, it gets deformed and hence no longer remains spherical. Also, there can be a decrease in its volume.

Science Part 1 Gravitation Exercise Question 1.
What are Newton’s laws of motion?
Answer:
(1) Newton’s first law of motion: An object continues to remain at rest or in a state of uniform motion along a straight line unless an external unbalanced force acts on it.

(2) Newton’s second law of motion: The rate of change of momentum is proportional to the applied force and the change of momentum occurs in the direction of the force.

(3) Newton’s third law of motion: Every action force has an equal and opposite reaction force that acts simultaneously.

Gravitation Exercise 10th Class Question 1.
According to Newton’s law of gravitation, every object attracts every other object.
Thus, if the earth attracts an apple towards itself, the apple also attracts the earth towards itself with the same force. Why then does the apple fall towards the earth, but the earth does not move towards the apple?
Answer:
The earth and the apple move towards each other, but the magnitude of the displacement of the earth is negligible relative to that of the apple. Also the observer is located on the earth.
[Note: The mass of the earth is far greater than that of an apple. Hence, the magnitude of the acceleration of the earth is negligible relative to that of the apple.]

Gravitation Class 10 Question And Answer Question 2.
The gravitational force due to the earth also acts on the moon because of which it revolves around the earth. Similar situation exists for the artificial satellites orbiting the earth. The moon and the artificial satellites orbit the earth. The earth attracts them towards itself but unlike the falling apple, they do not fall on the earth, why?
Answer:
This is because of the velocity of the moon and the satellites along their orbits. If this velocity was not there, they would have fallen on the earth.

Gravitation Class 11 Maharashtra Board Question 1.
According to Newton’s law of gravitation, the earth’s gravitational force is higher on an object of larger mass. Why doesn’t that object fall down with higher velocity as compared to an object with lower mass?
Answer:
F = ma and F = \(\frac{G M m}{r^{2}}\)
∴ Acceleration, a = \(\frac{G M}{r^{2}}\). This is independent of the mass (m) of the object. Hence, an object of larger mass and an object of lower mass fall down with the same velocity.

Question 3.
Explain the term gravitational force. What is gravitation?
Answer:
There exists a force of attraction between any two particles of matter in the universe such that the force depends only on the masses of the particles and the separation between them. It is called the gravitational force and the mutual attraction is called gravitation.

Question 4.
State Newton’s universal law of gravitation. Express it in mathematical form.
Answer:
Newton’s universal law of gravitation :
Every object in the Universe attracts every other object with a definite force. This force is directly proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between them.

Mathematical form: Consider two objects of masses m₁ and m₂. We assume that the objects are very small spheres of uniform density and the distance r between their centers is very large compared to the radii of the spheres (Fig. 1.8).

The magnitude (F) of the gravitational force of attraction between the objects is directly proportional to m₁m₂ and inversely proportional to r²
∴ F ∝ \(\frac{m_{1} m_{2}}{r^{2}}\)
∴ F = \(G\frac{m_{1} m_{2}}{r^{2}}\)
where G is the constant of proportionality, called the universal gravitational constant.
[Note: In the textbook, the word object/body is used.
Newton’s law of gravitation applies to particles.]

(i) The value of the constant of gravitation does not change with the nature, mass or the size of the material particles. It does not vary with the distance between the two particles. It is also independent of the nature of the medium between the two particles. Hence, it is called a universal constant.

(ii) As the law of gravitation given by Newton is applicable throughout the universe and to all particles, it is called universal law.

[ Note: The centre of mass of an object is the point inside or outside the object at which the total mass of the object can be assumed to be concentrated to study the effect of an applied force. The centre of mass of a spherical object having uniform density is at its geometrical centre. The centre of mass of an object having uniform density is at its centroid. If the two bodies are spherical and of uniform density, the gravitational force between them is always along the line joining the centres of the two bodies and the distance between the centres is taken to be r. When the bodies are not spherical or have irregular shape or have nonuniform density, the force is along the line joining their centres of mass and r is taken to be the distance between the two centres of mass.]

Question 6.
If the distance between two bodies is increased by a factor of 5, (i) by what factor will the gravitational force change if the masses are kept constant? (ii) by what factor will the mass of one of them have to be altered, keeping the other mass the same, to maintain the same gravitational force between the two bodies?
Answer:
If the distance between two bodies is increased by a factor of 5,
(i) the gravitational force between the bodies will decrease by a factor of 25 if the masses of the bodies are kept constant.
(ii) the mass of one of them will have to be increased by a factor of 25, keeping the mass of the other body the same, to maintain the same gravitational force between the two bodies.
[Note : Gravitational force F ∝ \(\frac{1}{r^{2}}\) and F ∝ m₁m₂.]

Question 7.
(i) Determine the SI unit of the universal constant of gravitation from the formula for the gravitational force between two particles. Hence, state the CGS unit of the constant of gravitation. (ii) Define G (universal gravitational constant).
Ans. (i) According to Newton’s law of gravitation, the gravitational force between two particles is
F = \(G\frac{m_{1} m_{2}}{r^{2}}\)
where m₁ and m₂ are the masses of the two particles, r is the distance between them and G is the universal constant of gravitation.
∴ G = \(\frac{F r^{2}}{m_{1} m_{2}}\)

The SI unit of force is the newton (N), that of distance is the metre (m) and that of mass is the kilogram (kg).
The SI unit of G is \(\frac{\mathrm{N} \cdot \mathrm{m}^{2}}{\mathrm{kg}^{2}}\).
The CGS unit of G is \(\frac{\text { dyne } \cdot \mathrm{cm}^{2}}{\mathrm{g}^{2}}\).

(ii) F = \(G\frac{m_{1} m_{2}}{r^{2}}\).
∴ G = \(\frac{F r^{2}}{m_{1} m_{2}}\)
If we take m₁ = m₂ = unit mass and r = unit distance, numerically, G = F, i.e., G (universal gravitational constant) represents the magnitude of the gravitational force of attraction between two unit masses, separated by a unit distance.

Question 8.
State the importance of Newton’s universal law of gravitation.
Answer:
The importance of Newton’s universal law of gravitation :
This law explains successfully, i.e., with great accuracy,

• The force that binds the objects on the earth to the earth
• The motion of the moon and artificial satellites around the earth
• The motion of the planets, asteroids, comets, etc., around the Sun
• The tides of the sea due to the moon and the Sun.

Question 9.
Compare the gravitational force on a body of mass 1 kg due to the earth with the force on the same body due to another body of mass 1 kg at a distance of 1 m from the first body. (Mass of the earth = 6 × 10²⁴ kg, radius of the earth = 6400 km)
Answer:
In the first case, m₁ = 1kg,
m2 = 6 × 10²⁴ kg and r = 6400 km = 6.4 × 10⁶ m
The gravitational force on the body.

= \(\frac{G \times 6 \times 10^{24} \mathrm{kg}^{2}}{(6.4)^{2} \times 10^{12} \mathrm{m}^{2}}\)
In second case, m₁ = 1 kg
m₂ = 1 kg and r = 1m
Gravitational force on the body,

Question 10.
Explain the term the earth’s gravitational force.
(OR)
Write a short note on the earth’s gravitational force.
Answer:
The earth attracts every object towards it because of the gravitational force. As the earth’s centre of mass is at its centre, the gravitational force exerted by the earth on an object is directed towards the earth’s centre. Hence, an object released from a point above the earth’s surface falls vertically downward towards the earth.

If an object is thrown vertically upward, its velocity goes on decreasing due to the earth’s gravitational force on the object. At one stage, the velocity of the body becomes zero and later the body falls back to the earth.

Question 11.
Take two balls of different masses, go to the top of a building, drop them simultaneously and observe what happens to the balls.
Answer:
The balls reach the ground almost at the same time.

Question 12.
Take two similar pages from your notebook. Crumple one paper and allow this and the other paper to fall on the ground simultaneously. What do you observe?
Answer:
The crumpled paper reaches the ground before the other one.

Question 13.
Take a feather and a paper. Allow them to fall to the ground simultaneously. Which will reach the ground earlier? Why?
Answer:
There is no unique answer. It depends on the feather and paper. Upthrust due to air and force due to friction with air play very important roles here. The acceleration of a body depends on the resultant of the earth’s gravitational force on the body and the upthrust and the force of friction due to air.

Question 14.
From Newton’s law of gravitation, derive the formula for the acceleration due to gravity.
Answer:
Suppose that a body of mass m is released from a distance r from the centre (O) of the earth (Fig. 1.9). Let M be the mass of the earth. According to Newton’s law of gravitation, the magnitude of the earth’s gravitational force acting on the body Is
F = G\(\frac{M m}{r^{2}}\)
where G is the universal constant of gravitation.

The acceleration produced by this force, force F

This is the formula for the acceleration due to gravity or the gravitational acceleration due to the earth. This acceleration is directed towards the earth’s centre.

If h denotes the altitude, r = R + h, where R is the radius of the earth.
∴ g = \(\frac{G M}{(R+h)^{2}}\)
For a body on the earth’s surface, h = 0 ∴ g = \(\frac{G M}{R^{2}}\)
[Note: When we consider the gravitational interaction between the earth and a body on the surface of the earth or at some height above the surface of the earth, for many practical purposes we can assume that the earth behaves as if its mass were concentrated at the earth’s centre. The proof is not expected here.]

Question 15.
Explain the factors affecting the value of g.
Answer:
The value of the acceleration due to gravity, g, changes from place to place on the earth. It also varies with the altitude and depth below the earth’s surface. The factors affecting the’ value of g are the shape of the earth, altitude and depth below the earth’s surface.

(1) The earth is not perfectly spherical. It is somewhat flat at the poles and bulging at the equator. At the surface of the earth, the value of g is maximum (9.832 m/s²) at the poles as the polar radius is minimum, while it is minimum (9.78 m/s²) at the equator as the equatorial radius is maximum.

(2) As the height (h) above the earth’s surface increases, the value of g decreases. It varies as \(\frac{1}{(R+h)^{2}}\), where R is radius of the earth.

(3) In the interior of the earth, on average, the value of g is less than that at the earth’s surface. As the depth below the earth’s surface increases, the value of g decreases and finally it becomes zero at the centre of the earth.

Question 16.
If g = GM/r², then where will the value^ of g be high, at Goa Beach or on the top of the Mount Everest? (Practice Activity Sheet – 3)
Answer:
The value of g will be high at Goa Beach.

Question 17.
Why does an object released from the hand, fall on the earth?
Answer:
When an object is held in the hand, the gravitational force acting on the object due to the earth is balanced by the person holding the object. When the object is released from the hand, it falls on the earth due to the earth’s gravitational force.

Question 18.
Does the value of g depend on the mass of the falling body? Why?
Answer:
The value of g does not depend on the mass of the falling body.
The reason is the gravitational force on a body due to the earth is directly proportional to the mass of the body and for a given force, the acceleration of a body is inversely proportional to the mass of the body.

Question 19.
Define mass. State its SI and CGS units.
Answer:
The mass of a body is the amount of matter present in it. Its SI unit is the kilogram (kg) and CGS unit is the gram (g).
[Note: Mass has only magnitude, not direction. Thus, it is a scalar quantity.]

Question 20.
Define weight. State its SI and CGS units.
Answer:
The weight of a body is defined as the force with which the earth attracts it. Its SI unit is the newton and CGS unit is the dyne.

[Note : In the usual notation, the magnitude of the weight of a body on the earth s surface is W = \(\frac{G m M}{R^{2}}\) = \(m\frac{G M}{R^{2}}\) = mg. Thus, W ∝ g. Hence, weight varies just like the acceleration due to gravity. It is maximum at the poles and minimum at the equator. It decreases with altitude (ft) and depth (d) below the earth’s surface. It becomes zero at the earth’s centre. At a height above the earth’s surface, W = \(\frac{G m M}{(R+h)^{2}}\) at a depth d below the earth’s surface, W = \(\frac{G m M(R-d)}{R^{3}}\). Weight has magnitude and direction (towards the earth’s centre). It is a vector quantity.]

Question 21.
As per the request of one of his friends from the equator, Rahul buys 100 grams of silver at the north pole. He hands it over to his friend at the equator. Will the friend agree with the weight of the silver bought? If not, why?
Answer:
The weight of a body is given by W = mg, where m is the mass of the body and g is the acceleration due to gravity, g varies from place to place. The value of g at the equator is less than that at the north pole (as well as the south pole). Hence, the weight of the silver bought at the north pole would be less when the silver is weighed at the equator. Therefore, Rahul’s friend will disagree about the weight of the silver.
[Note: The mass being independent of the value of g, Rahul’s friends will agree about the mass of the silver.]

Question 22.
What is the difference between mass and weight of an object? Will the mass and weight of an object on the earth be the same as their values on Mars? Why?
Answer:
The mass of an object is the amount of matter present in it. It is same everywhere in the Universe and is never zero. It is a scalar quantity and its SI unit is kg. The weight of an object is the force with which the earth (or any other planet/ moon/star) attracts it. It is directed towards the centre of the earth. The weight of an object is different at different places on the earth. It is zero at the earth’s centre. It is a vector quantity and its SI unit is the newton (N). The magnitude of weight = mg.

The mass of an object will be the same on the earth and Mars, but the weight will not be the same because the value of g on Mars is different from that on the earth.

Question 23.
Explain the term free fall and state the corresponding kinematical equations of motion in the usual notation.
Answer:
When a body falls in air, there are three forces acting on the body : (1) the gravitational force due to the earth, acting downward (2) the force of buoyancy (upthrust) due to air, acting upward I (3) the force due to friction with air (called air resistance), acting upward (being always in the direction opposite to that of the velocity of the body).

Under certain conditions, the force of buoyancy due to air and friction with air can be ignored compared to the gravitational force of the earth. In that case (near the earth’s surface) the body falls with almost uniform acceleration (g). Whenever a body moves under the influence of the force of gravity alone, it is said to be falling freely. Strictly speaking, this is true only if the body falls in vacuum.

The kinematical equations of motion, in the usual i notation, are
v = u + gt, s = ut + \(\frac{1}{2}\) gt² and v² = u² + 2gs.
If the initial velocity (u) of the body is zero,
v = gt, s = \(\frac{1}{2}\)gt² and v² = 2 gs.

Question 24.
During a free fall, will a heavier object accelerate more than a lighter one?
Answer:
No. The two objects will have the same acceleration.

Question 25.
If you had to calculate the mass of the earth, how would you do it?
Answer:
If the acceleration due to gravity (g), the constant of gravitation (G) and the radius of the earth (R) are known, the mass of the earth (M) can be calculated using the formula g = \(\frac{G M}{R^{2}}\)

Question 26.
What is gravitational potential energy?
(OR)
Define gravitational potential energy.
Write the formula for it.
Answer:
The energy stored in a body due to the gravitational force between the body and the earth is called the gravitational potential energy.

Gravitational potential energy of a body of mass m = \(-\frac{G M m}{R+h}\), where G = gravitational constant, M = mass of the earth, R = radius of the earth, h = height of the body from the surface of the earth.

[Note : As the body is bound to the earth due to the earth’s gravitational froce, the gravitational potential energy of the body is negative. If the body is given kinetic energy equal to \(\frac{G M m}{R+h}\) the body will overcome the earth’s gravitational force. It will then move to infinity and come to rest there.]

Question 27.
What is escape Velocity?
(OR)
Define escape velocity.
Answer:
When a body is thrown vertically upward from the surface of the earth, the minimum initial velocity of the body for which the body is able to overcome the downward pull by the earth and can escape the earth forever is called the escape velocity.

Question 28.
Explain the term escape velocity.
(OR)
Write a short note on escape velocity.
Answer:
In general, when a body is thrown vertically upward from the earth’s surface, its velocity goes on decreasing and after some time the body falls back to the ground. If its initial velocity is increased, the maximum height attained by it is more, but it does fall back to the ground. If the initial velocity is increased continuously, for a particular initial velocity, the body can overcome the earth’s gravitational force and move to infinity and come to rest there. This velocity is called the escape velocity.

Question 29.
Using the law of conservation of energy, obtain the expression for the escape velocity.
Answer:
Here, we shall not consider the effects of air. Suppose a body of mass m is thrown vertically upward from the surface of the earth. Let the initial velocity of the body be the escape velocity (v_sec).

When the body is on the earth’s surface, its total energy Ex = kinetic energy + potential energy = \(\frac{1}{2} m v^{2} \text { esc }\) + \(\left(-\frac{G m M}{R}\right)\) where G = universal gravitational constant, M = mass of the earth and R = radius of the earth.
Thus, E₁ = \(\frac{1}{2} m v_{\mathrm{esc}}^{2}-\frac{G m M}{R}\)
When the body moves to infinity and comes to rest there, its total energy,

According to the law of conservation of energy,
E₁ = E₂.

This is the required expression.

Question 30.
Express escape velocity in terms of g and R.
Answer:
Escape velocity, vesc = \(\sqrt{\frac{2 G M}{R}}\)
Now, g = \(\frac{G M}{R^{2}}\)
∴ GM = gR²

Question 31.
Express escape velocity in terms of G, R and ρ (the earth’s density)
Answer:

Give scientific reasons:

Question 1.
If a feather and a stone are released from the top of a building simultaneously, the stone reaches the ground earlier than the feather.
Answer:
(a) The motion of a body falling in air accelerated due to the earth’s gravitational force on the body. The force due to buoyancy of air acts on the body in the upward direction. As the body falls, the friction with air opposes its motion.

(b) This opposition due to air depends on the size, shape, density and velocity of the body. It Is greater for a feather than for a stone. Hence, the stone has greater downward acceleration than the feather. Therefore, the stone reaches the ground earlier than the feather though ‘they are released simultaneously from the same height.

Question 2.
The weight of a body is different on different planets.
Answer:
(1) The weight of a body of mass m on the surface of a planet of mass M and radius R is
W = \(\frac{G m M}{R^{2}}\) usuai notation).

(2) For a given body, its mass is constant. G is the universal constant of gravitation. Different planets have different masses and radii such that the ratio (M/R²) is not the same. Hence, the weight of a body is different on different planets.

Question 3.
With a specific initial velocity, we can jump higher on the moon than on the earth.
Answer:
The acceleration due to gravity on the moon is about \(\frac{1}{6}\) of that on the earth. Hence, with a specific initial velocity, we can jump higher on the moon than on the earth. This can be seen from the equation h = u²/2g.

Distinguish between the following:

Solution:
Data : T = 3.156 × 107 s,
r = 1.5 × 10¹¹ m, v =?

= 2.987 × 10⁴ m/s = 29.87 km/s
This is the speed of revolution of the earth.

Question 2.
Assuming that the earth performs uniform circular motion around the Sun, flnd the centripetal acceleration of the earth. [Speed of the earth =3 × 10⁴ m/s, distance between the earth and the Sun = 1.5 × 10¹¹ m]
Solution:
Data: v = 3 × 10⁴ m/s, r=1.5 × 10¹¹ m
Centripetal force = \(\frac{m v^{2}}{r}\) = ma
∴ Centripetal acceleration of the earth,

= 6 × 10^-3 m/s²
It is directed towards the centre of the Sun.

Question 3.
What will be the gravitational force on 60 kg man on the Moon, Mars and Jupiter? Are they the same? Why?

G = 6.67 × 10^-11 N.m2/kg
F₁ =?, F₂ =?, v₁ =?, t₁ =?, v₂ =?, t₁ =?

This is far greater than F₁.

Solution:
Data: \(\frac{M_{2}(\text { planet })}{M_{1}(\text { earth })}\) = 3
D₁ (earth) = 12800 km

g₁ (earth) = 9.5 m/s², g₂ (planet) = ?

v² = u² + 2 gs .
=2 gs …..(as u = 0 m/s)
= 2 × 9.8 m/s² × 19.6 m
= (19.6 m/s)²
∴ v = 19.6 m/s (downward velocity)
The velocity with which the body hits the i ground = 19.6 m/s (downward).

Question 13.
A stone on a bridge on a river falls into the river. If it takes 3 seconds to reach the surface of water, find (i) the velocity of the stone at the instant it touches the surface of water (ii) the height of the bridge from the surface of water.
Solution:
Data: u = 0 m/s, t = 3 s,
g = 9.8 m/s², v = ?, h = ?
(i) v = u + gt = 0 m/s + 9.8 m/s² × 3 s
= 29.4 m/s
The velocity of the stone at the instant it touches the surface of water = 29.4 m/s

(ii) s = ut + \(\frac{1}{2}\)gt²
= 0 m/s × 3 s + \(\frac{1}{2}\) (9.8 m/s²) (3 s)²
= 4.9 × 9 m = 44.1 m
∴ The height of the bridge from the surface of water = 44.1 m.

Question 14.
A stone is dropped from rest from the top of a building 44.1 m high. It takes 3 s to reach the ground. Use this information to 1 calculate g.

Data: s = 490 m, a = g = 9.8 m/s²,
u = 0 m/s, s = ut + \(\frac{1}{2}\)at²
∴ 490 = 0 × t + \(\frac{1}{2}\) × 9.8 × t² = 4.9t²
∴ t² = \(\frac{490}{4.9}\)
∴ t = 10 s This is the required time.

The forelimbs are short and used for support during locomotion. The hind limbs are long and strong, used for jumping when on land and for swimming when in water.

The eyes are large and protruding. Since the neck is absent, such eyes help in looking around. The tympanum is present.

f. Lizard.
Answer:
Classification:
Kingdom: Animalia
Phylum: Chordata
Class: Reptilia
Characters:

• Multicellular organisms without cell wall
• Organ-system grade organization
• Bilaterally symmetrical
• Triploblastic and Eucoelomate.

The lizard is a cold-blooded reptile. The limbs are weak and do not support the body weight, hence lizard is seen creeping. But the feet are provided with pads and suckers due to which lizards are well- adapted to climb on the vertical walls. The exoskeleton has fine scales. The body is divisible into head, neck and trunk. The capacity to regenerate is developed in lizards, hence it can produce the lost tail or limbs. The mode of reproduction is egg laying. It feeds on insects with the help of long and sticky tongue.

g. Elephant.
f. Lizard.
Answer:
Classification:
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Characters:

• Multicellular organisms without cell wall
• Organ-system grade organization
• Bilaterally symmetrical
• Triploblastic and Eucoelomate.

Elephant is the terrestrial, herbivorous mammal adapted to survive in hot and humid tropical forests.
It is a mammal and hence shows viviparity and milk secretion. The body is divisible into head, neck, trunk, and tail. The proboscis is a characteristic feature of the elephant which is actually modified nose.

h. Jellyfish.
Answer:
Classification:
Kingdom: Animalia
Sub-kingdom: Non-chordata
Phylum: Cnidaria or Coelenterata
Characters:

• Multicellular organisms without cell wall
• Tissue grade organization
• Radially symmetrical
• Diploplastic and Acoelomate

Jellyfish or Aurelia is a coelenterate. Its body is medusa. It appears as a transparent balloon seen floating in the marine waters. Since it has appearance like a jelly, it is known commonly as jellyfish. There are tentacles provided with cnidoblasts or stinging cells. Tentacles are used for catching the prey. Cnidoblasts are used to secrete a toxin which paralyses the prey.

Question 3.
Write in brief about progressive changes in animal classification.
Answer:
There were different methods of classification of animals.

1. The first classification method was given by the Greek philosopher Aristotle. He took into account the criteria like body size, habits and habitats of the animals. This method was called artificial method of classification.
2. The same artificial method was used by other scientists such as Theophrastus, Pliny, John Ray, Linnaeus, etc.
3. Further due to advances in science the references were changed and there were some new methods of classification proposed.
4. The system of classification called ‘Natural system of classification’ was then proposed. This system of classification was based on criteria such as body organization, types of cells, chromosomes, bio-chemical properties, etc.
5. Later, Dobzhansky and Meyer gave the system of classification based on evolution.
6. In 1977, Carl Woese has also proposed the three domain system of animal classification.

Question 4.
What is the exact difference between grades of organization and symmetry? Explain with examples.
Answer:
I. Grades of organization:
(1) The grades of organization mean the way an organism has different body formation.
(2) Unicellular organisms like amoeba have a single cell in the body and hence the organization in its body is called protoplasmic grade of organization.
(3) Some organisms have only cells in their body which is called cellular grade of organization, e.g. Poriferans.
(4) Some have tissues e.g. Coelenterates. They are said to have tissue grade organization. Some have organs, they are said to have organization-organ grade, e.g. Platyhelminthes. All other higher animals have organ-system grade organization.

II. Symmetry:
(1) Symmetry on the other hand shows the base of the body formation.
(2) The symmetry can be understood by taking an imaginary cut through the animal body.
(3) Based on the symmetry there can be three types.
(4) In asymmetric animals, there is no symmetry in any plane, e.g. Amoeba.
(5) The bilateral symmetry is the one in which an imaginary axis can pass through only one median plane to divide the body into two equal halves. Most of the animals have bilateral symmetry and hence their organs are arranged in symmetric way on both the sides.
(6) The imaginary cut passing through the central axis but any plane of body aan -give more than one equal half. The organs of such animals are arranged in a radius of an imaginary circle, e.g. Cnidarians and some echinoderms.
Both grades of organization and symmetry are the bases for classifying animals into different phyla.

Question 5.
Answer in brief.

Answer:
Kingdom: Animalia
Phylum: Chordata
Subphylum: Vertebrata
Class: Pisces
Subclass: Elasmobranchii (Cartilaginous)
Example: Scientific name: Scoliodon sorrakowah.
Common name: Shark

b. Write four distinguishing characters of phylum – Echinodermata.
Answer:
Distinguishing characters of Echinodermata:

1. Marine organisms with skeleton made up of calcareous spines. Calcareous material on the body hence the name is Echiodermata. Some are sedentary while some are free swimming.
2. Body is triploblastic, eucoelomate and radially symmetrical when adult. The larvae are bilateral symmetrical.
3. Locomotion with the help of tube-feet which are also used for capturing the prey.
4. Echinoderms have regeneration capability. Hence they can restore their lost parts.
5. Most of them are unisexual.
6. Examples; Starfish, sea-urchin, brittle star, sea cucumber, etc.

c. Distinguish between butterfly and bat with the help of four distinguish properties.
Answer:
Butterfly:

1. Butterfly is classified as Non-chordate.
2. It is included in class Insecta of phylum Arthropoda.
3. Butterfly has three pairs of legs and two pairs of chitinous wings.
4. Butterfly is a diurnal (active during day) insect.
5. Butterfly lays eggs which hatch into larva. Larva develops into pupa and pupa metamorphoses into an adult.

Bat:

1. Bat is classified as a Chordate.
2. It is included in class Mammalia of subphylum Vertebrata.
3. Bat has one pair of legs and a pair of patagium which are used for flying. Patagium has bones.
4. Bat is a nocturnal (active at night) mammal.
5. Bat is a viviparous animal that gives birth to live young ones. Young ones are fed by milk secreted by mammary glands.

d. To which phylum does Cockroach belong? Justify your answer with scientific reasons.
Answer:
(1) Cockroach belongs to the phylum Arthropoda and class Insecta.
(2) Scientific reasons for placement of Cockroach in the phylum Arthropoda:

• The body is covered by chitinous exoskeleton.
• Jointed appendages present, three pairs of walking legs and two pairs of membranous wings.
• Body is eucoelomate, triploblastic, bilaterally segmented and segmented.
• Respiration by spiracles and tracheal tubes.

Question 6.
Give scientific reasons.
a. Though tortoise lives on land as well as in water, it cannot be included in class-Amphibia.
Answer:

• When tortoise lives on the land, it respires with the help of lungs.
• When in water, it puts out its nares (nasal openings) out of the water and breathes air.
• It cannot take up oxygen dissolved in water. In both the habitats it respires with the help of lungs. In case of true amphibians, this is not the case.
• They can breathe in water with the help of skin and on land with the help of lungs.
• Tortoise also has exo-skeleton which is lacking in Amphibia. Therefore, tortoise cannot be included in class Amphibia.

b. Our body irritates if it comes in contact with jellyfish.
Answer:

• Jellyfish is a coelenterate that has cnidoblasts bearing tentacles.
• These cnidoblasts inject toxins to paralyse the prey at the time of feeding.
• When jellyfish comes in contact with our body, this toxin is released causing reaction to our skin.
• Therefore, our body gets irritation when we come in contact with jellyfish.

c. All vertebrates are chordates but all chordates are not vertebrates.
Answer:

• All chordates possess notochord in some period of their development.
• All vertebrates also have notochord during embryonic life, which is later replaced by vertebral column.
• Therefore all vertebrates are chordates.
• But some chrodate’s like Urochordata and cephalochordata do not possess vertebral column and hence they are not vertebrates.

d. Balanoglossus is connecting link between non-chordates and chordates.
Answer:

• Balanoglossus shows some characters of non-chordates.
• It also has notochord as in case of chordates.
• Since it shares the characters of non-chordates and chordates, from the view point of evolution, it is called connecting link between them.

e. Body temperature of reptiles is not constant. (Board’s Model Activity Sheet)
Answer:

1. Reptiles are cold-blooded animals.
2. The thermoregulatory system is not there in their bodies.
3. Their body temperatures, fluctuate as per the environmental temperatures.
4. Therefore, the body temperature is not maintained at constant level in reptiles.

Question 7.
Answer the following questions by choosing correct option.
a. Which special cells are present in the body of sponges (Porifera)?
1. Collar cells
2. Cnidoblasts
3. Germ cells
4. Ectodermal cells
Answer:
1. Collar cells
Explanation: Porifera animals are attached to the substratum. They do not show locomotion. For gathering and catching the food, they need to produce a current in the water. For this purpose, they have characteristic collar cells in their body. Germ cells and ectodermal cells are seen in all other phyla. Cnidoblasts are characteristic feature of coelenterates.

b. Which of the following animals’ body shows bilateral symmetry?
1. Starfish
2. Jellyfish
3. Earthworm
4. Sponge
Answer:
3. Earthworm
Explanation: When an imaginary plane passing through only one axis can divide the body into two equal halves, then it is called bilateral symmetry. Such symmetry is shown only by earthworm. Sponge body is asymmetrical while starfish and jellyfish are radially symmetrical.

c. Which of the following animals can regenerate it’s broken body part?
1. Cockroach
2. Frog
3. Sparrow
4. Starfish
Answer:
4. Starfish
Explanation: Cockroach, sparrow and frog cannot perform regeneration. Only echinoderms show power of regeneration. So only starfish can regenerate its broken part.

d. Bat is included in which class?
1. Amphibia
2. Reptilia
3. Aves
4. Mammalia
Answer:
4. Mammalia
Explanation: Bat gives birth to young ones and they also possess mammary glands. Amphibia, Reptilia and Aves do not show such features. Therefore, bat is included in Mammalia.

Use your brain power: (Text Book Page No. 74)

(A) Animals like gharial and crocodile live in water as well as on land. Are they amphibians or reptiles?
Answer:
Ghariyal and crocodile are reptiles. They can swim in water and crawl on land. But they can respire only with the help of lungs. Their breathing is through nostrils. Even when in water, they have to inhale and exhale by coming up to the surface of water for air. Amphibians can breathe through the skin when in water and by lungs when on land. They also have hard exoskeleton which amphibians do not have. Hence, ghariyal and crocodile are not amphibians, but they are reptiles.

(B) Animals like whale, walrus live in water (ocean). Are they included in Pisces or Mammalia?
Answer:
Whale and walrus are aquatic and marine mammals. They do not belong to class Pisces. They do not have gills to breathe in dissolved oxygen in water. Neither they have scales on the body nor can they lay eggs. Whales and walrus have mammary glands like all other mammals. They give birth to live young one. They breathe only with the help of lungs by putting their nostrils out of the water at surface. Hence they are included in Mammalia.

Write short notes on:

Question 1.
(1) Benefits of classification.
Answer:

• Studying the different animals becomes easy when they are placed under different groups.
• When few representative animals of the particular group are studied then the idea about other animals belonging to that group also becomes clear.
• The animal evolution becomes easier to follow after studying classification.
• The identification of animals can be done accurately.
• Relationship of the different animals with each other and with other groups can be understood clearly.
• Habitat of each animal and its role in nature is understood by classification.
• Various adaptations are understood by learning classification.

Question 2.
Germinal layers.
Answer:

• During the initial embryonic period of any multicellular animal there is formation of germinal layers or germ layer.
• These germ layers give rise to new tissues in the developing animal.
• The primitive animals were diploblastic i.e. they have only two germ layers called ectoderm and endoderm.
• The higher animals are triploblastic, having three germ layers; ectoderm, mesoderm and endoderm.
• Cnidarians are diploblastic while all other animals are triploblastic.

Question 3.
Coelom.
Answer:

• Coelom means body cavity. It is situated between the body wall and the internal organs of the body.
• The coelom is formed during early embryonic life in case of multicellular animals. It is formed from either mesoderm or gut.
• Coelom when present in the body, those animals are called eucoelomate. Phylum Annelida onwards are eucoelomate animals. They are animals with true body cavity.
• Those animals in which coelom are absent are called acoelomate animals. Porifera, Cnidaria and Platyhelminthes are acoelomate animals.
• When coelom is not formed from mesoderm or gut, but formed from other tissues, it is called pseudocoelom. Only Aschelminthes animals have such coelom and hence they are called pseudocoelomate.

Question 4.
Notochord.
Answer:

• Notochord is an important feature of Chordates.
• Notochord is supporting rod like structure.
• This structure is present on the dorsal side of the animals.
• It keeps the nervous tissue separated from the rest of the tissues.
• In Hemichordates, the notochord is present in the proboscis.
• In Urochordates, the notochord is present in the tail region of the free swimming larvae.
• In Cephalochordates, the notochord lies throughout the length of the body.
• In vertebrates, notochord is replaced by the vertebral column.

Answer:
Time to time, different scientists have tried to classify the animals. Greek philosopher Aristotle was the first to perform the animal classification. Aristotle classified the animals, according to the criteria like body size, habits and habitats. Classification proposed by Aristotle is known as ‘Artificial method’. Besides Aristotle, artificial method of classification was followed by Theophrastus, Pliny, John Ray and Linnaeus. Later on, ‘Natural system of classification’ was followed. Natural system of classification was based on various other criteria. By the time, system of classification based on evolution was also brought into practice. It was used by Dobzansky and Meyer. Recently, Carl Woese has also proposed the animal classification.

Answer:
Class Amphibia consist of animals which are strictly aquatic only during their larval stages. At that time they breathe through their gills. Tadpoles are such stages which later metamorphose to form adult frog. Adult frog respires with the help of skin when in water and with lungs when on land. Thus, it is a true amphibian. For performing cutaneous respiration, i.e. respiration through skin, they lack exoskeleton in any form. The skin is also kept moist by staying near the water bodies. Amphibians do not have a neck but eyes are bulging and prominent, this solves the problems of vision.

Paragraph based questions:

1. Read the paragraph and answer the questions given below:
Locomotion is considered as an important j characteristics of the animals. However, animals belonging to Porifera are said to be sedentary. Every 1 other phylum has typical locomotory organs. E.g. Nereis crawls with the help of parapodia, whereas earthworm buries in soil by setae. Spiders have four pairs of walking legs, crab has five while all insects have three pairs of walking legs. The walking legs are also called appendages. Starfish moves with the help of tube feet. Snails and bivalves use muscular foot for locomotion. Birds flying with their spread out wings and fish swimming with their fins, both have spindle-shaped body tapering at both the ends. While flying or swimming such body offers least resistance during locomotion. Mammals have two pairs of limbs while animals like snakes are limbless. Other animals belonging to the class of snakes also have very weak limbs which make them creep on the ground.

In addition to these organs, there are network of blood capillaries, nerve network, etc. which is spread from head to toes.

Question 2.
Why is earthworm called as friend of farmers? (Get Information: Text Book Page No. 69)
Answer:
Earthworms move through the soil in the farms and fields. They feed on the detritus in the soil. They also help in decomposition of the organic matter. When the soil is loosened due to their activities, the roots of the crops grow well. They enrich the soil by their excreta which act as fertilizers. All these facts make earthworm, a farmer’s friend.

Question 3.

Answer:
Leeches are blood sucking ectoparasite. In Ayurveda leech is used to remove impure blood and blood clots. Such blood is sucked up by leeches and then the patient gets some relief. In the leech body there is. a substance called hirudine which prevent blood clotting as it sucks up the blood. This hirudine is also used for medicinal purpose.

Question 4.
What is chitin? (Find out: Text Book Page No. 70)
Answer:
Chitin is a type of polysaccharide. Its chemical formula is (C8H13O5N)n. It is a long-chain polymer of N-acetylglucosamine, which is actually a derivative of glucose. It is a primary component of cell walls in fungi, the exoskeletons of arthropods, such as crustaceans and insects. In many medicines chitin is used. The industrial processes and the biotechnological experiments also use chitin.

Question 5.
Let’s Think: (Text Book Page No. 70)
(i) What types of benefit and harm occur to human from animals of phylum-Arthropoda?
Answer:
Some insects are very useful for us. We get many products from them. e.g. Honey bee, Lac insect, Silk worm, are the insects that provide us with honey and wax, lac and silk respectively. The culture experiments are done on these insects for large scale production of these substances. Butterflies help in the pollination of crops and are thus helpful for the farmers and gardeners. Lady bug beetle is an insect which acts as a natural pest control as it attacks the other harmful insect pests.

In biological pest control methods it is widely used. Some insects, on the contrary are very harmful. Mosquito, bed bugs, lice are blood sucking parasites which can spread the diseases. Mosquito is a vector for dengue, filariasis and malaria. Some are biting insects that can cause wounds, some cause allergies of various kinds. The grains and crops are destroyed to great extent by the insects. In this way the insects belonging to the phylum Arthropods are harmful to health, wealth and peace of mind too.

(ii) Which are the animals from phylum Arthropoda those have shortest and longest life span?
Answer:
The shortest life span: May fly – About 24 hours. The longest life span : Lobster (Homarus americanus) – About 100 years.

(iii) Why has it been said that only insects directly compete with humans for food?
Answer:
The standing crop in the fields can be totally ruined by insects. The locust can damage the crops when they attack in thousands at a time. The grains are also infested by variety of insects like ants, weevils, beetles, etc. Therefore, we can say that only insects compete with humans for food.

अभिव्यक्ति

‘बुजुर्ग आदर-सम्मान के पात्र होते हैं, दया के नहीं इस सुवचन पर अपने विचार लिखिए।
उत्तर :
हमें यह बात याद रखनी चाहिए कि आज जो व्यक्ति बुजुर्ग है वह हमेशा बूढ़ा और असहाय नहीं था। वह भी पहले युवा था। उसने अपने परिवार का पालन-पोषण और उसकी देखरेख की थी। उसने तरह-तरह की समस्याओं का सामना किया था और उन्हें अपने तरीके से हल किया था। उसे जीवन जीने का अनुभव है। लेकिन वृद्ध हो जाने पर किसी-किसी परिवार में बुजुर्गों को किनारे कर दिया जाता है। उनकी सलाह या सुझाव को कोई महत्त्व नहीं दिया जाता। इस तरह के व्यवहार से बुजुर्गों को अपने सम्मान पर ठेस लगती महसूस होती है।

किसी-किसी परिवार में तो बुजुर्गों के खाने-पीने की भी किसी को चिंता नहीं रहती। घर के लोग अपने में मगन रहते हैं और बुजुर्गों का कोई ख्याल नहीं रखता। बुजुर्गों को खाने-पीने के लिए उनका मुँह ताकना पड़ता है। हमें यह बात नहीं भूलनी चाहिए कि हम इन बुजुर्गों की संतान हैं। उनको पर्याप्त सम्मान देना और उनकी हर प्रकार से देखरेख करना हमारा फर्ज है। बुजुर्गों की प्रसन्नता और उनके आशीर्वाद से ही परिवार फूलता-फलता और खुशहाल रहता है। इसलिए बुजुर्गों को हमें सदा आदर-सम्मान देना चाहिए और उनकी देखरेख करनी चाहिए।

मेरा प्रिय वैज्ञानिक’ विषय पर निबंध लेखन कीजिए।
उत्तर :
यों तो दुनिया में एक-से-एक बड़े वैज्ञानिक हैं, पर मेरे प्रिय वैज्ञानिक तो सर जगदीशचंद्र बोस ही हैं। सर जगदीशचंद्र बोस की बात ही निराली है। उन्होंने यह सिद्ध करके बता दिया कि पेड़-पौधे भी हमारी तरह साँस लेते हैं और उन्हें पानी और भोजन की आवश्यकता होती है। उनमें भी जान होती है। यदि पेड़-पौधों को सताया या कष्ट दिया जाए, तो वे बीमार हो जाते हैं और उनकी प्रकृति के विरुद्ध उन्हें भोजन दिया जाए अथवा जहरीला रसायन दिया जाए, तो वे मर जाते हैं। वैसे पेड़-पौधों के संपर्क में रहने वाले प्रत्येक व्यक्ति को मालूम होता है कि पेड़-पौधों को नुकसान पहुँचाने या विषैले पदार्थों के संपर्क में आने से वे क्षतिग्रस्त या मृत हो सकते हैं, पर इस बात को सिद्ध किया था सर जगदीशचंद्र बोस ने।

अपने शोध को सिद्ध करने के लिए उन्होंने खुद चुंबकीय क्रेश्कोग्राफ नामक यंत्र तैयार किया। उन्होंने इस यंत्र की सहायता से सब के सामने अपने प्रयोग से यह सिद्ध कर दिया कि पेड़-पौधों में जीवन होता है और प्राणियों की तरह उनमें भी विभिन्न क्रियाएँ होती हैं। इस प्रकार के सूक्ष्म रहस्य का उद्घाटन करने वाले वे पहले वैज्ञानिक थे। वे सच्चे अर्थों में एक महान वैज्ञानिक थे। ऐसे महान वैज्ञानिक पर हमें गर्व है।

बुढ़ापा बहुधा बचपन का पुनरागमन होता है’ इस विषय पर अपने विचार 25 से 30 शब्दों में व्यक्त कीजिए।
उत्तर :
कहते हैं, बुढ़ापा बचपन का ही एक रूप है। वृद्धावस्था : में मनुष्य की हरकतें बच्चों जैसी हो जाती हैं। इस अवस्था में मनुष्य के अंग-प्रत्यंग कमजोर हो जाते हैं और उन्हें बच्चों की तरह दूसरों का सहारा लेना पड़ता है। दिमाग कमजोर हो जाता है। दाँत गिर जाते हैं और मनुष्य का मुँह बच्चों की तरह पोपला हो जाता है। इतना ही नहीं, बच्चों की तरह ही वृद्धों को भी मान-अपमान की परवाह नहीं होती। जिस तरह लोग बच्चों की बातों पर ध्यान नहीं देते, उसी तरह वृद्धों की बातों पर भी कोई ध्यान नहीं देता। उनकी इच्छा-अनिच्छा का भी कोई महत्त्व नहीं होता। इस तरह वृद्धावस्था और बचपन की अधिकांश बातों में समानता होती है। इसलिए कहा जा सकता है कि बुढ़ापा बहुधा बचपन का पुनरागमन होता है।

उत्तर :
लड़कों और बूढ़ों के बीच पीढ़ियों का अंतर होता है। लड़कों और बूढ़ों में हर बात को लेकर अंतर होना स्वाभाविक है। अधिकांश बूढ़ों की आदत होती है कि वे हर बात को अपने ढंग से सोचते हैं। वे उसमें अपने जमाने की विचारधारा थोपने की कोशिश करते हैं। इसका कारण यह है कि किसी चीज के बारे में उनकी एक धारणा बनी होती हैं। हर बात को वे अपने पैमाने पर कसने की कोशिश करते हैं। जब कि नई पीढ़ी के लड़कों की सोच अलग ढंग की होती हैं। उन्हें पुराने दकियानूसी विचार पसंद नहीं आते। इसलिए बात-बात पर दोनों के विचारों में टकराव होता है। इस तरह लड़कों और बूढ़ों में स्वाभाविक विद्वेष होता है।

Question (a)
What makes the writer call Mary Kom ‘a legend’?
Answer:
A legend is a famous person, icon or superstar in a particular field. Mary Kom is a famous woman as an Indian boxer. The field is male dominated, but with her efforts and determination she earned name and fame, so in real sense she is a legend not only to the writer but also to all Indians and a real ‘torch-bearer’ for Indian women.

Question (b)
What prime quality did Mary Kom display during her first attempt in Olympic Games? What was her bad luck?
Answer:
Mary practised for Olympics with the male boxers. Her coach was not allowed to accompany her but she went on with confidence, because she had done her homework and was well prepared with her coach. She could play with good tactical knowledge. In semi-finals she was fighting against Adams, a clever counter puncher but Mary was scoring well, but the judges were not pressing the buttons and favouring her rival. So it was her bad luck that she lost in the semi-finals.

Note down the points in your notebooks, expand the points in two separate paragraphs of about 15 to 20 lines each. Suggest suitable titles for each:
Answer:
Two beautiful Creations of God-Men and Women

For the topic

Men cannot look after their family well compared : to women. It is still believed that men are supposed to be the bread winners and be able to support their wives and children. But now a days many women do this work very easily. Women have proved that they can do anything if given a chance. Now they have started working in Army with men.

In politics, they have proved that they can work better than men. Games like cricket, football, wrestling were the monopoly of men but now by entering in these fields they are proving they can do anything better than men. In astronomy, medicines, teaching they are in the forefront. It is important to remember that differences between men and women do not mean that one gender is less important than the other.

Against the topic

Being raised in a socially conscious environment, we believe men and women are generally equal and should be treated as such. But there are certain fields in which women can’t work as they do not possess the physical strength to work in adverse conditions like protecting our borders. They are rarely found as coal miners. Women cannot climb electricity poles and work on power transformers. They cannot fight in wars or battles. They are not found in off-shore oil drilling platforms.

‘Music is the medicine of the mind’. Narrate an experience that leads to the above conclusion. Write it in your own words, in

Answer:
Music is the medicine of the mind Music is good therapy. It is particularly effective because it registers on multiple sites of the brain. This means that even if the brain is very badly affected by a stroke or illness, there are s^till parts of the brain that recognise music.

I remember how upset all of us were when Grandfather suffered a stroke. The left side of his body and almost all of his face were affected. The once great and active Grandpa now lay still on the bed and had to be fed through a tube going down his nostrils. Little Rani could not stop weeping.

Grandfather had once presented me with a mobile phone. He knew my love for music and had told me I could download my favourite songs and create a playlist and listen to them whenever I wanted to.

I would sit by Grandfather’s bed whenever I was at home and had finished my studies and play the songs and listen to them.

One evening, to my surprise, I saw a shadow of a smile beginning to appear on Grandpa’s face. At first I couldn’t believe it. Then it became more definite and prominent. Grandpa was actually smiling!

That was one of the happiest moments during his illness.
