Solution
Correct Answer:
107m
To find the order of magnitude of a number x⋅10n:
- If x≤10≈3.16, the order of magnitude is 10n.
- If x>10≈3.16, the order of magnitude is 10n+1. Here, x=6.37, which is greater than 3.16. Therefore, the order of magnitude is 106+1=107 m.
This medium difficulty physics question is from the chapter physics and measurement, covering the topic of order of magnitude. It appeared in the 2025 exam.
