a) 12 Hz
b) 24 Hz
c) 48 Hz
d) 96 Hz

Respuesta :

Despina

Answer:

  • [a] 12 Hz

Explanation:

To calculate frequency, we can divide the number of times the event occurs by the length of time.

  • Frequency = number of times the event occurs/time

We are given, A pendulum passes the nose of an observer 24 times in 2 seconds

So,

  • Number of times the event occurs = 24 times
  • Time = 2 seconds

Substitute the required values in the above formula,

  • Frequency = 24/2
  • Frequency = 12 Hz

Hence, the required Frequency is option [a] 12 Hz
