The drag force on a plane is proportional to the density of the air. By what factor does the drag force change if a plane goes from an altitude 5.5 km to 11 km? The atmospheric pressure goes from to atm in going from 5.5 km to 11 km. Assume that the plane is at level flight and flies at the same speed.
D) 1
E) 2
