Answer 1

(4)

Converting 4.5 fm to m,

$\begin{gathered} 4.5\text{ fm}\times(\frac{10^{-15}\text{ m}}{1\text{ fm}})=4.5\times10^{-15}\text{ m} \\ \end{gathered}$

Converting m to nm;

$(4.5\times10^{-15}\text{ m})\times(\frac{10^9\text{ nm}}{1\text{ m}})=4.5\times10^{-6}\text{ nm}$

Therefore, 4.5 fm equals to 4.5×10^(-6) nm.

(5)

Converting 450 miles/hr to feet/s;

$\begin{gathered} 450\text{ miles/hr}=450\text{ miles/hr}\times(\frac{5280\text{ feet}}{1\text{ mile}})\times(\frac{1\text{ hr}}{60\text{ min}})\times(\frac{1\text{ min}}{60\text{ sec}}) \\ =660\text{ feet/sec} \end{gathered}$

Therefore, 450 miles/hr equals to 660 feet/sec.
