Question

A Pendulum oscillates 40 times in 4 seconds. Find its time period and frequency.​

Answer 1

Answer:

10Hz

Explanation:

Number of oscillation = 40

Total time taken. = 4 Seconds

Time period = time/No. of oscillation

4sec/40 = 1/10 = 0.1sec

Frequency = Number of oscillation per sec.

Number of oscillation/Time

40/4 sec = 10per sec. or 10Hz
