Question

a simple pendulum takes 60 second to complete 20 oscillation what is the time period of the pendulum​

Answer 1

Explanation:

Hola !

Total time taken by pendulum = oscillation/time taken

=20/60

=⅓

Answer 2

Given :

Time taken to complete 20 oscillation = 60 seconds

To Find :

Time period of the simple pendulum

Solution :

Time period of a simple pendulum can be defined as the time taken to complete one oscillation.

We are required to find the time period of a simple pendulum which completes 20 oscillation in 60 seconds. So,

20 oscillations completed in 60 seconds

1 oscillation completed in $\frac{60}{20}$ seconds

                                         = 3 seconds

Therefore, the time period of the simple pendulum is found to be 3 seconds.
