1 Hertz is Equal to (a) 1 Vibration Per Minute, (b) 10 Vibrations Per minute, (c) 60 Vibrations Per Minute

Answer: The correct option is: Option (c) 60 vibrations per minute

To explain the problem, we will need to have a compact notion about the definition of frequency and the definition of the unit of frequency [Hertz (Hz)].

Frequency: The number of complete vibrations of a particle over a certain given amount of time is called as the frequency of that object.

Hertz (Hz): The unit Hertz (or Hz in abbreviation)is defined as, the number of complete vibrations of an object in one second (1 second).

Hence, by the problem if the frequency is equal to 1 Hertz then the object must be vibrating once in every second.

That means, 1 vibration in 1 second

That means, 60 vibrations in 60 seconds or 1 minute.

Thus, the correct option is Option (c).
