Question

if a pendulum takes 1 min to complete 100 oscillation. find out its time period and frequency

Answer 1

we know that time period= number of oscillation per second

1 minute=60 s

∴ 100 oscillation = 60 s                                          (equation 1)

let time period be =x

so 1 oscillation= x                                                     (equation 2)                        

by doing cross multiplication of equation 1 and equation 2 we get

100x=60 oscillation

x=60/100 s

x=3/5 s

x=0.6 s

thank you so much
