5. What is the reading for this measurement, in the correct significant figures?

A. 36.55
B. 36.5
C. 37
D. 35.5

Answer :

Final answer:

The correct reading for this measurement, in the correct number of significant figures, is 36.5.

Explanation:

To determine the correct number of significant figures in a measurement, we follow a set of rules

  1. Non-zero digits are always significant.
  2. Any zeros between non-zero digits are significant.
  3. Leading zeros (zeros before the first non-zero digit) are not significant.
  4. Trailing zeros (zeros after the last non-zero digit) are significant if there is a decimal point present.

In the given measurement reading, which is 36.5, we have three non-zero digits ('3', '6', and '5'). These are all significant. There are no leading zeros, and the trailing zero after the decimal point is significant. Therefore, the measurement reading has three significant figures.
