A tank with a square base of area 1.0 m^-2 is divided by a vertical partition in the middle. The bottom of the partition has a smallhinged door of area 20 cm^2 . The tank is filled with water in one compartment, and an acid (of relative density 1.7) in the other, both to a height of 4.0 m. compute the force necessary to keep the door close.

the distance between two vertical poles is 100m and the height of one of them is double the other. The angle of elevation of their tops at the middle point of the line joining their feet are complimentary. Find the height.
