Answer
(a) $10^{0}~m$
(b) $10^{-2}~m$
(c) $10^{1}~m$
(d) $10^{2}~m$
(e) $10^{7}~m$
Work Step by Step
A person is about $1.7~m\approx10^{0}~m$. The length of a fly is about $10~mm\approx10^{-2}~m$. A car is about $5~m\gt\sqrt {10}~m$, so the length of a car is $\approx10^{1}~m$. A 747 airplane is about $80~m\approx10^{2}~m$. The length from coast to coast in the United States is about $5000~km\approx10^{7}~m$
