3. When a ball is set rolling on the ground, it stops after, sometimeWhich of the following opposes the motion of the ball ?

a. Resistance due to air.

b. Force of friction between the ball and the ground.

c. Both of these.

d. None of these.

4. Why a passenger standing in a bus falls backward when'the bus is suddenly set in motion ?

a. Because action and reaction are equal and opposite.

b. Because, in this case, the action becomes greater than the reaction.

c. Because, in this case, the reaction is greater than the action.

d. Because the lower part of the body begins to move along with the bus while the upper part (of the body) tends to remain at rest due to inertia of rest.

5. 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.
