Answer:
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
