Question

. A simple pendulum takes 60 seconds to complete 3 oscillations. Calculate its time period. Explain

Answer 1

Answer:

it takes 60 seconds to complete 20 oscillation

so it would take 60/20

i.e 3sec to complete one oscillation so time period =3sec

Answer 2

Answer:

time period= time taken/no of oscillations

=60/3

=20s/per oscillation

hope this will be helpful dear

is so pls folo me :-)!
