Explanation:
To understand why 1 hertz is equal to 60 vibrations per minute, we need to have a clear understanding of what hertz and vibrations per minute mean.
Hertz:
- Hertz (Hz) is the unit of frequency, which measures the number of occurrences of a repeating event per second.
- It is named after Heinrich Rudolf Hertz, a German physicist who first conclusively proved the existence of electromagnetic waves.
- In simpler terms, hertz measures how many times an event occurs in one second.
Vibrations per minute:
- Vibrations per minute is a unit of frequency that measures the number of vibrations or oscillations occurring in one minute.
- It is commonly used to describe the frequency of certain mechanical devices or systems.
Conversion:
Now, let's convert 1 hertz to vibrations per minute.
- Since 1 hertz represents 1 occurrence per second, we need to find the equivalent number of occurrences in one minute.
- There are 60 seconds in one minute, so we can multiply 1 hertz by 60 to find the number of occurrences in one minute.
- Therefore, 1 hertz is equal to 1 * 60 = 60 vibrations per minute.
Conclusion:
- Option D, which states that 1 hertz is equal to 60 vibrations per minute, is the correct answer.
- This conversion is based on the fact that there are 60 seconds in one minute.
