airplane in flight has a pressure difference between the lower and upper wing surface; this provides an upward force that balanc

Dvinal [7]

Answer:

4523.17365 Pa

Explanation:

m = Mass of plane = 77000 kg

F = Force = Weight = $mg$

g = Acceleration due to gravity = 9.81 m/s²

A = Total area of wings = 167 m²

The pressure difference would be

$\Delta P=\dfrac{F}{A}\\\Rightarrow \Delta P=\dfrac{77000\times 9.81}{167}\\\Rightarrow \Delta P=4523.17365\ Pa$

The pressure difference required to keep the plane aloft is 4523.17365 Pa

Mice21 [21]

Answer:

h/(m*c)

Explanation:

Hi!

Lets denote the units of X as [X]

Since the dimentions of h are:

$[h] = \frac{ML^{2}}{T}$

If we divide [h] by the units of mass, we get:

$\frac{[h]}{[m]} = \frac{L^{2}}{T}}$

Also we know that:

$[c] = \frac{L}{T}$

So:

$[\frac{h}{mc}] = \frac{L^{2}}{T}}*\frac{T}{L}=L$

Therefore

h/(mc) has dimentiosn of length
