Q.3 A simple pendulum takes 32 s to complete 20 oscillations. What is the time period of the pendulum?

Number of oscillations = 20

Total time taken to complete 20 oscillations = 32 s

Time period = \(\frac{total time taken}{number of oscillation} = \frac {32}{20} \) = 1.6 seconds

Therefore, the time period of the pendulum is 1.6 seconds.
