Answer 2

The time period of a simple pendulum is 3 seconds.

Explanation:

It is given that,

Number of oscillations of a simple pendulum is 24.

Time taken to complete 24 oscillations is 72 seconds

Let f is the frequency of the simple pendulum. It is given by :

f=\dfrac{24}{72}f=

72

24

f = 0.334 Hz

If T is the time period. It is given by :

T=\dfrac{1}{f}T=

f

1

T=\dfrac{1}{0.334}T=

0.334

1

T = 2.99 s

or T = 3 s

So, the time period of a simple pendulum is 3 seconds. Hence, this is the required solution.
