Question

A simple pendulum takes 44 seconds to complete 20 oscillations. What is its time period?​

Answer 1

Explanation:

time taken = 44

total oscillations = 20

Tim period = time taken / total oscillations

44/20= 2.2

Answer 2

Given:

time taken = 44 sec

no of oscillation = 20

To Find:

Time period

Solution:

We know,

The time period is the time taken to complete one oscillation

By Unitary Method

For 20 Oscillation time taken = 44 sec

For 1 Oscillation time taken = 44/20 = 2.2 sec

So, the Time period is 2.2 sec
