Question

A pendulum swings back and froth 20 times in 34 sec. What is its time period?​

Answer 1

Answer:

The pendulum performs Simple Harmonic Motion while moving back and forth. Hence its motion can be described as oscillatory. Time period of any oscillatory body is defined as the time taken to complete 1 full oscillation. Therefore , 1 oscillation is completed in 34/20 = 1.7 seconds.
