Chapter 4.2, Problem 67PE

(a)

To determine

The atmospheric pressure at sea level, if If a is the height (in km) above sea level, then the pressure $P\left(a\right)$ (in mmHg) is approximated by $P\left(a\right)=760e^{-0.13a}$.

(b)

To determine

The atmospheric pressure at the altitude of $8.848\text{km}$. If a is the height (in km) above sea level, then the pressure $P\left(a\right)$ (in mmHg) is approximated by $P(a)=760e^{-0.13a}$ and $a=8.848\text{Km}$.
