Question

5. A pendulum oscillates 40 times in 4 seconds. Find its time period and frequency The sound from a mosquito is produced when it vibrates its wings at an​

Answer 1

Answer:

time period = 40/4 --> 10

frequency = 1/10 ---.> 0.1

time period is equal to the time pendulum take to make one oscillation. Frequency is equal to how many oscillations can the pendulum make in 1 second hence it is equal to 1/ time period
