Question

A pendulum oscillates 54 times in 6 seconds. Find its time period and frequency.

Answer 1

Answer:

so time period of the pendulum is 0.12 secs. frequency = 1/time period= 1/0.12 Hz = 8.33 Hz

Answer 2

Answer-

Time Period=9 sec

Frequency= 9Hz

Explanation-

Time period is defined as the time required to complete one oscillation.

Frequency is defined as the number of oscillations per unit time.

Time = 6 sec.

Time Period = (Time taken) / (Number of Oscillations)

Time Period = (6/54) = 9 sec.

Frequency = (Number of Oscillations)/ (Time taken)Frequency = (54/6) = 9Hz.

Hope I am correct. If I am wrong then please inform.
