Question

simple pendulum makes 15 oscillation in 45 seconds. What is the period and frequency of it’s oscillation?​

Answer 1

Answer:

1/3 or 3.333/s

Explanation:

Frequency of oscillation formula = oscillations/time

So,

15/45 (simplification by 5) =

3/9 (simplification by 3 =

1/3 or we can convert to decimal as 3.333/s

Answer 2

Answer:

If the simple pendulum makes 15 oscillations in 45 seconds, then the period is 3 sec and the frequency of it’s oscillation is 0.33 Hz. ​

Explanation:

A simple pendulum consists of a small metal ball suspended by a long thread from rigid support, such that the bob is free to swing back and forth.

For 15 oscillation it takes 45 sec

For one oscillation Time period = 45/15 = 3sec

Frequency = 1/ Time period

= 1/3 = 0.33 Hz
