Question

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

Answer 1

time required =32 sec
no of oscillations =20
time period ,T =(time required)/(no of oscillations)
=32/20=1.6 s      

Answer 2

Time period is the time duration for completing one oscillation.

$T = \frac{32}{20} = 1.6 seconds$
