Aperson drives to the top of a mountain. on the way up, the person’s ears fail to “pop,” or equalize the pressure of the inner ear with the outside atmosphere. the pressure of the atmosphere drops from 1.010 x 10^5 pa at the bottom of the mountain to 0.998 x 10^5 pa at the top. each eardrum has a radius of 0.40 cm. what is the pressure difference between the inner and outer ear at the top of the mountain? a. 1.2 x 10^3 pa b. 1.1 x 10^5 pa c. 1.0 x 10^2 pa d. 1.2 x 10^2 pa

Aballoon is rising vertically upwards at a velocity of 10m/s. when it is at a height of 45m from the ground, a parachute bails out from it. after 3s he opens his parachute and decelerates ata a constant rate 5m/s.when. (a) what was the height of the parachutist above the ground when he opened his parachute? (b)how far is the parachutist from the balloon at t=3s? (c)with what velocity does the parachutist hit the ground? (d)after how long does the parachutist hit the ground after his exist from the balloon?
