Question

Give reason . 1) moving air provides a lift. 2) If you were on a mountain , would you expect the weight of air above you ( air pressure ) be greater than or less than its now. 3) Air weighs less than water , would you expect the preassure exerted by water be greater than or less than the pressure exerted by the same amount of air

Answer 1

a) moving air has some pressure in it. when the air hits a person, the third law of motions acts on and the change of energy cause a lift
b) If you are on a mountain the pressure of air gets lower. 
c) The pressure exerted by water will be higher than air due to more weight than air. 

Answer 2

Explanation:

a) moving air has some pressure in it. when the air hits a person, the third law of motions acts on and the change of energy cause a lift

b) If you are on a mountain the pressure of air gets lower.
