Question

A simple pendulum makes 20 oscillation 40 s what is the time period and frequency of it is oscillation

Answer 1

Frequency =No. Of Oscillation/time

ATQ,

20/40=1/2 Hertz

Time period= 1/F

ATQ,

1/1/2=2 sec

Pls mark me

Answer 2

frequency = no. of osillation/time taken

= 20/40

=1/2

=0.5Hz

time period=1/frequency

=1/0.5

=2 sec
