Question

Sohan has a pendulum which ossilates 625 times in 25 seconds what will bethe frequencyand time period of this pendulum

Answer 1

20 Hz is right answer

Answer 2

Here's your answer

Frequency = No. of oscillations in one second

It is given that

Oscillation in 25 seconds = 625

Then, Oscillations in 1 second= 625/25

= 25 /s

= 25 hz ( 1/s = hz)

Time period = Time taken to complete an oscillation

= 1/frequency

= 1/25 = 0.4 sec
