You are given these approximate measurements:
(a) The radius of Earth is 6 × 106 m,
(b) The length of a human body is 6 ft,
(c) A cell's diameter is 10−6 m,
(d) The width of the hemoglobin molecule is 3 × 10−9 m,
(e) The distance between two atoms (carbon and nitrogen) is 3 × 10−10 m. Write these measurements in the simplest possible metric prefix forms (in either nm, Mm, μ m, or whatever works best).
