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

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .

it is a solid
