Find the rate at which it grows in nanometers per second. Because the distance between atoms in a molecule is on the order of 0.1 nm, your answer suggests how rapidly atoms are assembled in this protein synthesis. nm/s 7. Question from 1 4: Uncertainty Measurement and Significant Figures (7-16) The habitable part of Earth's surface has been estimated to cover 60 trillion square meters.

Explanation / Answer

1/62" = 0.0161 inches

1 inch = 0.0254 m

so 0.0161 inches = 0.0004096 m = 409677.41 nm

1 day = 86400 seconds

(1/62)in/s= 409677.41 nm / 86400 seconds

= 4.74 nm/s
