Answer:
10Hz
Explanation:
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

Explanation:
Time Period is Time taken by pendulum to complete 1 oscillation.
So, 4 / 40 = 0.1 seconds.
Frequency is number of oscillation completed by pendulum in 1 second.
So , 40 / 4 = 10Hz
Therefore, Time Period = 0.1s ; Frequency = 10Hz
Hope it helps
If so then pls mark as brainliest answer
Thankyou ✌️
