Question

A string vibrates 2400 times in 2 minutes find its frequency and time period.​

Answer 1

Answer:

The frequency is 20 hertz and time period is 0.05

Explanation:

To find the frequency,

  We have to divide the no. of vibrations with the time taken:

=> no. of vibrations/ time taken  

=> 2400/2*60 = 20 hertz;

and time period:

=> 1/frequency  

=> 1/20
