Best ResponseYou've already chosen the best response.4pressure is the force per unit area....P=F/A so divide force by area to get answer to first question

Best ResponseYou've already chosen the best response.1its not force applied on an object.. its how much force is coming on a unit area.. !!

Best ResponseYou've already chosen the best response.4in the second one,when an airplane takes off, nothing happens to air pressure..what happens is that..pressure on the lower side of wings becomes greater than the upper one and it rises due to pressure difference......in the question,its not specified on which side of wing....so overall air pressure remains the same
