Answer 1

Answer:

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
