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

Answer 1

Numbers of oscillations = 20
Time taken = 32 sec

Time period of a pendulum is the time taken by it to complete one oscillation.
So, time period of the given pendulum = $\frac{Timetaken}{NumberofOscillations}=\frac{32}{20}=1.6s$
