A pendulum makes 20 oscillations in 4 seconds. find its time period and frequency.

Given that 20 oscillations are made by the pendulum for 4 sec. So, It makes 5 oscillations are made by the pendulum for 1sec. We know that the number of oscillations made per second (5 oscillations per second ) is called its frequency ∴ Frequency = 5 Hz Time period = 1/ Frequency Time period = 1/ 5 Time period = 0.2 sec

HOPE IT HELPS you...
PLZ mark me as a BRAINLIST

khushirani57: abd whats your name...
