Question

a simple pendulum takes 15 seconds to complete 5 oscillations what is time period of Pendulum how many oscillations will it complete in a minute​

Answer 1

Answer:

In 15 seconds, oscillations = 5

therefore , in 1 second, oscillations = 5/15 =

1/3

Therefore, in 60 seconds , no. of oscillations = 1/3×60 = 20

Answer 2

Answer:

time period = no. of oscillations/time taken to complete those oscillation

=5/15

=1/3...
