## College Physics (4th Edition)

We can rank the lengths from smallest to greatest: $c = e \lt a = b \lt d$
We can convert each length to units of meters: (a) $1~\mu m = 1\times 10^{-6}~m$ (b) $1000~nm = 1000\times 10^{-9}~m = 1 \times 10^{-6}~m$ (c) $100~ 000~pm = 100~ 000\times 10^{-12}~m = 1 \times 10^{-7}~m$ (d) $0.01~cm = 0.01\times 10^{-2}~m = 1 \times 10^{-4}~m$ (e) $0.000~000~000~1~km = 0.000~000~000~1\times 10^{3}~m = 1 \times 10^{-7}~m$ We can rank the lengths from smallest to greatest: $c = e \lt a = b \lt d$
