Question

A pendulum produces 20 oscillations in 5 seconds. Calculate its time period. How

many times it vibrates in one minute?​

Answer 1

Answer:

First calculate the frequency i.e the no of oscillations for 1 sec from the data we know that the frequence is 4 hertz (i.e for 1 sec = 20/5). Now we know time period T= 1/f where f is the frequency therefore Time period (T) = 1/4 = 0.25 sec. Hence, the pendulum requires 0.25 seconds to complete one oscillation.

Answer 2

$hello$

First calculate the frequency i.e the no of oscillations for 1 sec from the data we know that the frequence is 4 hertz (i.e for 1 sec = 20/5).

Now we know time period T= 1/f where f is the frequency

Therefore, Time period (T) = 1/4 = 0.25 sec.

Hence, the pendulum requires 0.25 seconds to complete one oscillation.
