Question

1 hertz is equal to ___________ .

• A. 1 vibration per minute
• B. 10 vibration per minute
• C. 60 vibrations per minute.
• D. 600 vibrations per minute.

Answer 1

The correct option is C

60 vibrations per minute.

1. Frequency is defined as the number of oscillations per second.
2. $Frequency=\frac{Numberofoscillations}{Timetakeninseconds}$
3. The unit of frequency is $hertz$.
4. $1hertz$ is defined as one oscillation per second.
5. $$\begin{gathered} Ifnumberofoscillation=60 \\ Thetotaltimetaken=1minute=60seconds \\ Frequency=\frac{60}{60} \\ =1hertz. \end{gathered}$$

Hence, option C is correct.
