Question
How many significant figures are correctly present in the measurement $0.000014650 \text{ m}$?
Answer: B
💡 Solution & Explanation
According to significant figure rules, leading zeros are merely placeholders and are never significant. The non-zero digits ($1, 4, 6, 5$) are significant. The trailing zero is significant because it appears after a decimal point. Therefore, the number has exactly 5 significant figures.
