Question

A simple pendulum completes 20 oscillations in 40s.What will be the time period of the pendulum?

Answer 1

Answer:

Answer-

Time taken = 40 secs

No. of oscillations = 20

Time Period = Time Taken/ No. of oscillations

                     = 40/20

                     = 2 secs

Answer 2

The time period of the pendulum is 2 seconds.

Explanation:

In the given question, it is already mentioned that the number of oscillations is 20.

And the time taken for those oscillations to complete is 40 secs.

As we all know that,

The formula for the time period is,

              Time period = Time taken/ Number of oscillations

Therefore,

the time period of the simple pendulum = $\frac{40}{20}$

                                                         =2 secs.

The same method goes for any other rate and magnitude.
