The rate of change of atmospheric pressure P with respect to altitude h is proportional to P, provided that the temperature is c

jonny [76]

Answer:

$P = 101.5 e^{-0.00015h}$

Step-by-step explanation:

dP/dh = kP

dP/P = k dh

ln P = kh + C

Now, using the points given,

ln 101.5 = C, so C = 4.62

ln 87.3 = k*1000 + 4.62

k = -0.00015

So, we have

ln P = -0.00015 h + ln 101.5

P = 101.5 e^(-0.00015h)

Answer:

f:h = 1 : 10

Step-by-step explanation:

$\frac{f}{g}=\frac{1}{4}\\\\Cross multiply,\\\\4f = g\\\\g = 4f ------------(I)\\\\\frac{g}{h}=\frac{2}{5}\\\\\frac{4f}{h}=\frac{2}{5} from(I)\\\\\frac{f}{h}=\frac{2}{5*4}\\\\\frac{f}{h}=\frac{1}{5*2}\\\\\frac{f}{h}=\frac{1}{10}$
