Question

if a pendulum complete 16 oscillations in 20 srconds.find its time period and frequency.



step-by-step​

Answer 1

Explanation:

16 oscillations in 20 sec

time period is the time of one oscillation

therefore,

time period= 20/16

=1.25sec

frequency=1/time period

=1/1.25

=0.8sec^-1

Hope this helps you.
