Question

A pendulum of length 3m completes 20 oscillation in a certain time internal.

How many oscillation will a pendulum of length 12m complete in the same

duration?​

Answer 1

Answer:

1. The time taken to complete one oscillation is known as the time period of the pendulum.

Time Period = (Total time is taken)/ (Number of Oscillations)

Given: - 20 oscillations taking 32s to complete.

Therefore 1 oscillation will take = (32)/ (20) sec = 1.6 second

Therefore 1.6s is the time period of the pendulum.
