a person rides up a liftto a mountain top,but the person`s ears fail to "pop"-that is,thepressure of the inner ear does not equalize with the outsideatmosphere.the radius of each eardrum is 0.40cm.the pressureof the atmoshpere drops from 1.010 x 10^5 Pa at the bottom of thelift to 0.998 x 10^5 Pa at the top.
A. what is the pressure difference between the inner and outerear at the top of the mountain?
B. what is the magnitude of the net force on each eardrum?
