Question

caculate the time period of simple pendulum if it takes 45 seconds to complete 62 oscillation . give answer in factor

Answer 1

time period of the pendulum is the time taken for one oscillation.     time period= time taken for no. of oscillations/ no. of oscillations. here no. of oscillations= 40,  and time taken= 4seconds.  .time period for this condition is= 4/40 therefore the time period is=1/10th of 1 second. frequency of a pendulum is the no. of oscillations in one second. frequency= 1/ time period here time period=1/10 of a second frequency for this condition=1/1/10 therefore frequency=0.1
