A spring makes 60 revolution in 15sec,fine the period and the frequency of the vibration.

I want the correct answer

60rev/15sec = 4 rev/s = 4Hz that is the frequency

period = 1/frequency = 1/4 s/rev

The frequency of the vibration equal to 4

To find the period and frequency of vibration of a spring, we need to know the number of revolutions made by the spring and the time taken to complete those revolutions.

Given:
Number of revolutions = 60
Time taken = 15 seconds

To find the period, we need to divide the total time taken by the number of revolutions:
Period = Time taken / Number of revolutions

Period = 15 seconds / 60 revolutions
Period = 0.25 seconds

The period of vibration is 0.25 seconds.

To find the frequency, we need to take the reciprocal of the period:
Frequency = 1 / Period

Frequency = 1 / 0.25 seconds
Frequency = 4 Hertz

The frequency of the vibration is 4 Hz.

Therefore, the period of vibration is 0.25 seconds and the frequency is 4 Hz.
