Question

Calculate time-period of a simple pendulum which takes 72 seconds to complete 24
oscillations.

Answer 1

Answer:

3 seconds

Explanation:

Time period means the time taken by the pendulum to complete one oscillation.

In this case,

Time period = 72 (total time) ÷ 24 (total number of oscillation.)

72 ÷ 24 = 3

Thus, the time period of the simple pendulum is 3 seconds.

Answer 2

Answer:

3 seconds

Explanation:

The time period of a simple pendulum is the (time taken / Number of oscillations it makes in that particular time interval)

Time taken = 72 seconds

Number of oscillations completed in 72 seconds = 24

Therefore,

Time Interval = Time taken/ Number of oscillations

Time interval = 72/ 24

Tine interval = 3 seconds
