One meter is equal to 10 9 nanometers. How long in meters is 670 nanometers? 6.70 * 10 - 7 m

6.70 * 10 - 11 m

6.70 * 10 9 m

6.70 * 10 - 9 m

The answer to your question is: the first option

Explanation:

Meter is a unit of length in the SI, international system of units. Its symbol is m.

Nanometer is equivalent to 10⁻⁹ meters, as its name says it is used to measure extremely small particles.

-To solve this problem we use a rule of three.

1 meter ⇒ 10⁹ nanometers

x meters ⇒ 670 nanometers

Simplify

x = (670 x 1) / (10⁹)

x = 6.7 x 10 ⁻⁷ meters
