Question

The wool of a vicuna is finer than any other wool. The hair of this animal can be as thin as 0. 000006 meters. If the average thickness of human hair is approximately 8. 4 × 10-5 meters, what is the difference of the thickness of a human hair and a vicuna hair? A. 2. 4 × 10-5 meters B. 2. 4 × 10-6 meters C. 7. 8 × 10-6 meters D. 7. 8 × 10-5 meters.

Answer 1

Answer: To find the difference in thickness between a human hair and a vicuna hair, we need to subtract the thickness of a human hair from the thickness of a vicuna hair.

The thickness of a vicuna hair is given as 0.000006 meters, and the thickness of a human hair is approximately 8.4 × 10^(-5) meters.

Difference in thickness = Thickness of vicuna hair - Thickness of human hair

= 0.000006 meters - 8.4 × 10^(-5) meters

To subtract these values, we need to align the decimal points by converting 8.4 × 10^(-5) to the same decimal places as 0.000006, which is 6 × 10^(-6).

Difference in thickness = 0.000006 meters - 0.000006 meters

= 0

Therefore, the difference in thickness between a human hair and a vicuna hair is 0 meters. None of the given options (A, B, C, or D) are correct as they all have non-zero values for the difference.
