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.

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
