An airplane takes off at sea level and climbs to a height of 480 m. estimate the net outward force on a passenger's eardrum assuming the density of air is approximately constant at 1.3 kg/m3 and that the inner ear pressure hasn't been equalized.

net outward force on a passenger's eardrum is 0.6115 N

Explanation:

Change in pressure is calculated as follows

h= height of liquid column =480 m

ρ= density of liquid= 1.3 kg/m^3

putting values we get

ΔP= 6115 Pa

Area of the eardrum is approximately

=  1 cm^2

Therefore, net force F = AΔP

=

= 0.6115 N

we need answer choices

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
