Calculate time period of a simple pendulum if it takes 72 seconds to complete 24 oscillations

Anvisha [2.4K]

Answer:

The time period of a simple pendulum if it takes 72 seconds to complete 24 oscillation will be 3 seconds.

Step-by-step explanation:

Total number of oscillations = 24

Time taken to complete 24 oscillations = 2 seconds

So, the frequency 'f' of the simple pendulum will be:

$f=\frac{24}{72}$

$f=\frac{1}{3}$

Let 'T' be the time period.

$T=\frac{1}{f}$

$T=\frac{1}{\frac{1}{3}}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{1}{\frac{b}{c}}=\frac{c}{b}$

$T=\frac{3}{1}$

$T=3$

Therefore, the time period of a simple pendulum if it takes 72 seconds to complete 24 oscillation will be 3 seconds.
