Question

A simple pendulum take 10 seconds to complete 40 oscillations. the time period of this pendulum is​

Answer 1

The Answer of the Question:

Answer 2

Answer:

The time period of the pendulum is o.5s

Explanation:

In the given problem, a simple pendulum takes 80 seconds to complete 40 oscillation. To find the frequency, use the unitary method. There is 2 oscillations in one second.

The formula for the time period is as follows;

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

f

1

Here, T is the time period and f is the frequency.

Put f= 2 Hz.

T=\frac{1}{2}T=

T=0.5 sT=0.5s

Therefore, the time period of pendulum is 0.5 s.
