Question

how many significant figures: 0.012 km

Explanation:

Step1: Recall significant figures rules

Leading zeros (zeros before the first non - zero digit) are not significant. In the number \(0.012\), the leading zeros (the two zeros before 1) are not significant.

Step2: Identify non - zero digits

The non - zero digits in \(0.012\) are 1 and 2. So we count these non - zero digits. The number of non - zero digits (which are significant) is 2.

Answer:

2 (corresponding to the option with value 2, e.g., if the options are labeled as A. 4, B. 1, C. 3, D. 2, then the answer is D. 2)
