Answer 1

Explanation:

the second hand if a clock rotates along an axis it's centre is fixed. many people get confused with this. the motion of entire second hand if a clock is rotational motion while the motion of each point of the second hand is circular motion, except the point at which the second hand is attached to the clock. that point us stationary. therefore the velocity is changing as direction is changing at every point while the speed remains constant.
