Question

1.A simple pendulum takes 27 S to complete 20 oscillations.
What is the time period of the pendulum?

Answer 1

Answer: 1.35 s

Explanation:

Time period is the time taken by the pendulum to complete one oscillation.

Time period = time taken / total oscillations

                    = 27 / 20

                    = 1.35

Therefore, time period of pendulum = 1.35 s
