Question

If 20 oscillations are covered in 10 seconds , what is its time period​

Answer 1

2 seconds

When a simple pendulum makes 10 oscillations in 20 seconds, the time taken for each oscillation = 20/10 = 2 seconds. Hence, as the time period is calculated to be 2 seconds, the frequency of oscillation = 1/T = 1/ 2 = 0.5 Hertz.

Answer 2

hey mate here is ur answer

0.5s is time period

and frequency is 2Hz
