Answer:

Part A. 5.85 · 10^40 erg
Part B. 1.8 ⋅ 10^−2 mm

Step-by-step explanation:

<u>Multiply the numbers and find the product:</u>

3.9 ⋅ 10^33 × 1.55 ⋅ 10^7 =
3.9 × 1.5 · 10^(33 + 7) =
5.85 · 10^40

1.8 ⋅ 10^2 mm = 1.8·100 mm = 18 cm is too much for the human hair

<u>Therefore more reasonable number is:</u>

1.8 ⋅ 10^−2 mm
