Question

1. how many significant figures are present in the measurement 0.0048206 meters?

○ 4
○ 5
○ 7
○ 8

Explanation:

Step1: Recall significant figure rules

Leading zeros (zeros before the first non - zero digit) are not significant. Non - zero digits and zeros between non - zero digits are significant.
For the number \(0.0048206\), the leading zeros (the three zeros before 4) are not significant.

Step2: Identify significant digits

The non - zero digits and the zero between non - zero digits: 4, 8, 2, 0, 6. Let's count them: 4 is the first non - zero digit, then 8, 2, 0 (between 2 and 6), and 6. So we have 5 significant figures.

Answer:

5 (corresponding to the option "5")
