Question

The time period of a simple pendulum, that takes 42 seconds
to complete 20 oscillations, equals 2.1 seconds. true or false ​

Answer 1

Answer:

True.

Explanation:

Because 42 is divided by 20

Answer 2

The given statement is true.

• The frequency is the number of Oscillations per second. Time period is the reciprocal of the frequency.
• Calculating frequency = total oscillations/total time taken

Frequency = 20/42

Frequency = 0.47

• Calculating time period = 1/frequency

Time period = 1/0.47

Time period = 2.1 seconds

• Time period can also be directly calculated as the total time is taken/number of Oscillations.
