Question

A simple pendulum makes 20 oscillations in 5seconds. Calculate its frequency and time period.

Answer 1

Answer:

here is ur answer dude

Explanation:

10 sec ---> 20 oscillations

So, 1 sec ---> 2 oscillations

Hence frequency is 2 Hz

Time period is reciprocal of frequency.

So, T is 0.5 sec

hope it helps you

Answer 2

Answer:

20/5 =10 frequency

10 oscillations per sec =20  oscillations = time period
