1 hertz is equal to :

Options

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

Explanation

To determine what 1 hertz is equal to, we need to understand the definition of hertz in terms of vibrations.

**Step 1: Understand the definition of hertz.**
- Hertz (Hz) is a unit of frequency that measures the number of cycles or vibrations per second.

**Step 2: Convert hertz to vibrations per minute.**
- Since 1 hertz is equal to 1 vibration per second, we can convert this to vibrations per minute.
- There are 60 seconds in a minute, so:
\[ 1 \text{ Hz} = 1 \text{ vibration/second} \times 60 \text{ seconds/minute} = 60 \text{ vibrations/minute} \]

**Step 3: Conclusion.**
- Therefore, 1 hertz is equal to 60 vibrations per minute.

**Final Answer:**
1 hertz is equal to 60 vibrations per minute.
