Calculate time period of a simple pendulum if it takes 72 seconds to complete 24 oscillations

It takes 3 seconds for the pendulum to complete 1 oscillation.

Given to us:

Total number of oscillations = 24 oscillations,

The time period needed for 24 oscillations = 72 seconds,

The time period needed for 1 oscillation,

Hence, It takes 3 seconds for the pendulum to complete 1 oscillation.

The time period of a simple pendulum if it takes 72 seconds to complete 24 oscillation will be 3 seconds.          

Step-by-step explanation:

Total number of oscillations = 24

Time taken to complete 24 oscillations = 2 seconds

So, the frequency 'f' of the simple pendulum will be:

Let 'T' be the time period.

Therefore, the time period of a simple pendulum if it takes 72 seconds to complete 24 oscillation will be 3 seconds.
