An airplane flies 120 km at a constant altitude in a direction 30.0° north of east. a wind is blowing that results in a net horizontal force on the plane due to the air of 2.40 kn in a direction 10.0° south of west. how much work is done on the plane by the air?

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
