Answer 1

Answer:

(b) Motion of pendulum in an old wall clock

Answer 2

Answer: C) "Movement of a top"

Explanation:

• Rotatory motion is a type of motion in which an object rotates about its own axis.
• A bus which is coming down from Thirumala hills does not have an fixed axis of rotation as it is moving along the road.
• The motion of the pendulum is to and fro motion not a rotatory motion but it has a fixed axis.
