102.0 MHz (typical frequency for FM radio broadcasting)
Express your answer using four significant figures.
The frequency 102.0 MHz (megahertz) can be expressed using four significant figures as 102.0 MHz.
To express the frequency of 102.0 MHz using four significant figures, we can follow these steps:
1. Start with the original frequency, which is 102.0 MHz.
2. To express the answer with four significant figures, we count the number of digits from the leftmost non-zero digit to the rightmost non-zero digit.
- In this case, the leftmost non-zero digit is 1 and the rightmost non-zero digit is 2.
- Therefore, there are two significant figures in the original frequency.
3. To express the answer with four significant figures, we need to include two additional significant figures.
- The additional significant figures can be zeros in this case.
4. The final frequency with four significant figures is 102.0 MHz.
