Question

2. A pendulum oscillates 36 times in 3
seconds. Find its time period and frequency.​

Answer 1

Answer:

Given

36 oscillations => 3 sec

Time period is defined as time taken for 1 oscillation

1 oscillation =>3 / 36 sec

                     => 1/12 sec

so time period is 1/12 sec

Frequency is defined as number of oscillation made in one second

3 sec => 36 oscillations

  1 sec => 36/3oscillations

           => 12 oscillations

so frequency is 12 Hz
