The frequency is defined as the number of vibrations (or number of cycles) per second. For example, if a certain device oscillates with frequency of 1 Hz, it means it makes 1 complete vibration/cycle each second. The tuning fork in this problem has a frequency of f=75 Hz, therefore it makes exactly 75 cycles per second.

Answer:

N = 75 cycles per second

Explanation:

As we know that frequency is defined as the number of cycles per second

so here we can say that frequency is same as the number of cycles per second

so here given that

[tex]frequency = 75 Hz[/tex]

so here we have

Number of cycles per second = 75 Hz
