1. A light year is a unit of

a. time.

b. distance.

c. velocity.

d. intensity of light.

2. How does, saft straw work?

a. When air is sucked, a low pressure is created inside the straw. But pressure outside the straw remains high. This differenct in pressure forces the soda upwards.

b. When air is sucked, the force of adhesion between the soda and. straw is reduced. Due to this reduction in the magnitude of the adhesive force, the soda rises in the straw.

c. When air is sucked, eddy currents are produced inside the straw. These eddy currents force the soda to rise upwards.

d. All of these.

3. A stone, tied to a string, is being whirled round in a horizontal circle. The string suddenly breaks. What will be the motion of ther stone ?

a. The stone will continue to move in a circle fbr sometime.

b. The stone will fly off, in a straight line path, along the tangent.

c. The stone will immediately fall to the ground.

d. The stone will first move, along the radius of the circle, to the centre of the circle and finally drops to the ground.

4. What is the physital principle involved in skating ?

6. When a stone is thrown on a window pane, the glass is broken into pieces. However, when a high speed bullet passes. through the. window pane, it makes a clean hole. Why ?

a. Because the bullet is made of a special metal.

b. Because the particles of glass near the hole, cannot share the very quick motion of the bullet and remain undisturbed.

c. Because of both of these.

d. Because of none of these.

7. The force of attraction between any two bodies in this universe is known as

a. force of gravity.

b. force of gravitation.

c. centripetal force.

d. centrifugal force.

8. Which of the following is the Newton's law of motion?

a. Every body continues in its state of rest or of uniform motion in a straight line unless it is compelled by external forces to change that state.

b. The rate of change of momentum of a body is directly proportional to the impressed force and takes place in the direction of the force.

c. To every action, there is an equal and opposite reaction.

d. All of these.

9. Why sand is provided for high jumpers to fall on in place of hard ground

a. Because sand is cooler than the hard ground.

b. Because sand is hotter than the hard ground.

c. Because the jumper can penetrate some distance before commg to rest.

d. Because of none of these.

10. Which of the following statements is correct ?

a. It is easier to pull than to push a lawn roller.

b. It is easier to push than Ito pull a lawn roller.
