Question

A pendulum oscillates 40times in 4second. find its time period and frequency.​

Answer 1

Answer:

Time period = 40/4 = 10 seconds and frequency = 1/ time period = 1/10 Hz = 0.1Hz

Answer 2

Answer:

Frequency is defined as the number of oscillations per unit time. Time = 4 sec. Time Period = (4/40) = 0.1 sec. Frequency = (Number of Oscillations)/ (Time taken)Frequency = (40/4) =10Hz.
