Question

a simple pendulum vibrates 30 times in a minute wat is its timeperiod and frequency?

Answer 1

We know, frequency is the number of vibrations in one second.

Time period is the time taken in one vibration.

A simple pendulum vibrates 30 times in a minute that means it vibrates 30times in 60seconds.

So, Time period = 60/30 = 2s

Frequency, f = 1/T = 1/2 = 0.5 Hz.
