(a) What is a simple pendulum? Define the time-period of a simple pendulum.
(b) State whether the following statement is true or false:
The time-period of a given pendulum is not constant.
(c) In an experiment to measure the time-period of a simple pendulum, the time for 20 complete oscillations was found to be 36 s. What is the time-period of this pendulum?

Expert Answer:
(a) A simple pendulum consists of a small metal ball (called bob) suspended by a long thread from a rigid support, such that the bob is free to swing back and forth.
The time period of a simple pendulum is the time taken by the pendulum bob to make one complete oscillation.
(b) False
(c) Time for 20 complete oscillations = 36 s
Time fo 1 complete oscillation = 36/20 = 1.8 s
So, time period of the pendulum = 1.8 s
