Question

The atmospheric pressure on an object decreases as altitude increases. If a is the height (in km) above sea level,

Answer 1

Answer:

253 mmHg

Step-by-step explanation:

Since the atmospheric pressure, $P(a) = 760e^{-0.13a}$

when a = height (in km) = 8.47 km, then the atmospheric pressure P(a) is

$P(a) = 760e^{-0.13a}\\P(8.47) = 760e^{-0.13X8.47}\\P(8.47) = 760e^{-1.1011} \\P(8.47 )= 760 X 0.33251 \\P(8.47)= 252.7 mmHg$

P(8.47) ≅ 253 mmHg
