Ahydrogen atom has a diameter of about 10 nano meters.
a) express this diameter in meters.
b) express this diameter in millimeters .
c) express this diameter in micrometers.
answer my question
.

a) 10^-8 m  b) 10^-5 mm c) micrometer

Explanation:

nano means 10^-9

hence 10 nanometers =  10×10^-9 m = 10^-8 meters

millimeters means 10^-3 meters

10^-8m = 10^-5×10^-3m=10^-5 millimeter

micro meter means 10^-6 meters

10^-8m = 10^-2 ×10^-6 m = 10^-2 micrometer = 0.01 micrometer

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.
