Answer» -NUMBER of oscillations by the pendulum = 50 timesTotal time taken by the pendulum = 5 secTo Find :-The time period.The frequency.Analysis :-Here we are given with number of oscillations and the time taken by the pendulum.Firstly, divide the total time taken by the number of oscillations in order to find the time period.Then using the FORMULA of frequency, substitute the values we GOT such that, frequency is equal to ONE divided by time period.Solution :-Using the formula,Given that,Time = 5 secNo. of oscillations = 50 timesSubstituting their values,⇒ t = 5 / 50⇒ t = 0.1 secUsing the formula,Given that,Time period = 0.1 secSubstituting their values,⇒ f = 1/t⇒ f = 1/0.1⇒ f = 10 HzTherefore, the frequency is 10 Hz. |
