Question

a simple pendulam makes 10 oscillation in 20 second.what is time period and frequency of its own?

Answer 1

no. of oscillations = 10
time taken = 20 secs
time period = time / oscillations
                   = 20/10
                   = 2 secs
frequency = oscillations /time
                 = 10/20
                 = 0.5 Hz

Hope it helps
Thank you

Answer 2

hi friend

frequency= vibration / time duration
= 10/20
=.5Hz
time period = time duration/ vibration
=20/10
=2
