On an airplane's takeoff, the combined action of the air around the engines and wings of an airplane exerts a 8420-n force on the plane, directed upward at an angle of 69.0° above the horizontal. the plane rises with constant velocity in the vertical direction while continuing to accelerate in the horizontal direction. (a) what is the weight of the plane? n (b) what is its horizontal acceleration?

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.
