Question

Pendulum a makes 15 acillation in 5 sec and pendulum b makes 12 osclllation in 3 sec which has higher frequency

Answer 1

Answer:

Frequency = Total oscillations / Total Time

Pendulum A

15 oscillations in 5 seconds (Given)

Number of oscillations in 1 second will be -

= 15/5

= 3 Hz

Thus, frequency = 2.8 Hz

Pendulum B

8 oscillations in 4 seconds (Given)

Number of oscillations in 1 second will be -

= 8/4

= 2 Hz

Frequency = 2 Hz

Therefore, Pendulum A has a higher frequency
