1.	A simple pendulum make 20oscillations in 40 secondsWhat is the time period and frequency of itsoscillation
Answer» ANSWER: TIME Period = 2 seconds FREQUENCY = 0.5 Hz Explanation: Time Period : Time taken to complete one oscillation by the pendulum is called time period. Time take to complete 20 oscillations by the pendulum = 40 seconds Time take to complete 1 oscillation by the pendulum = $\frac{40}{20}$ seconds Time take to complete 1 oscillation by the pendulum = 2 seconds Therefore the Time Period of the pendulum is 2 seconds. __________________________________________________________ Frequency : It is the NUMBER of oscillations made by the body in one second. Frequency = ( $\frac{1}{Time \:Period}$ ) = ( $\frac{1}{2}$ ) = 0.5 Hz Therefore, The frequency of the pendulum is 0.5 Hz.
