Question

A pendulum oscillates 20 times in 4 seconds. Find its time period.​

Answer 1

Given - Oscillations: 20 times

Time: 4 seconds

To find - Time period

Solution - Time period can be calculated by the formula = Time taken/ number of oscillations.

Keep the values in the formula to find the value of time period.

Time period of pendulum = 4/20

Time period of pendulum = 1/5

Time period of pendulum = 0.2 seconds.

Hence, time period of the pendulum as per the given information is 0.2 seconds.

Answer 2

Answer:

Time period of pendulum = 4/20

Time period of pendulum = 1/5

Time period of pendulum = 0.2 seconds.

Hence, time period of the pendulum as per the given information is 0.2 seconds.
