human hair is about 0.0025 cm.
What is the distance from the sun to Mercury written in scientific notation?

Answer 1

Explanation:

You need a number between 1 and 10.

You need a power that shows 6 zeros plus one more.

Number = 5.8

power = 6 + 1 = 7

Answer: 5.8 * 10^7 km for the distance of Mercury to the sun.

The hair is 2.5 * 10^-3
