Question

A pendulum makes 30 oscilation in 36 seconds calculate t and f

Answer 1

Answer:

Given,

          Pendulum makes 30 oscillations in 36 seconds.

Find,

     

          Time period = ?

          Frequency   = ?

Answer,

             Time period = $\frac{Time}{Number of oscillations}$ = $\frac{36}{30}$ =  $\frac{12}{10}$ = 1.2 seconds

              Frequency  = $\frac{Number of oscillations}{Time}$ = $\frac{30}{36}$ = $\frac{10}{12}$ = 0.834 oscillation                                                                                  in one second
