Question

if a pendulum takes 1 minute to complete 15 oscillations, then what is the time period of the pendulum?

Answer 1

Answer:

Time period of the pendulum is 4 seconds.

Explanation:

Given,

A pendulum takes 1 minute to complete 15 oscillations.

To find: what is the time period of the pendulum.

Solution:

Time period is defined as the time taken by pendulum to complete it's one oscillation.

Time taken = t = 1 minute = 60 second

Using Unitary Method,

Time taken for 15 oscillation = 60 second

Then, Time taken for 1 oscillation = 60 / 15 = 4 second

Therefore, Time period of the pendulum is 4 seconds.
