A and B are two separate reservoirs of water. Capacity of reservoir A is double the capacity of reservoir Bdot Both the reservoirs are filled completely with water, their inlets are closed and then the water is released simultaneously from both the reservoirs. The rate of flow of water out of each reservoir at any instant of time is proportional to the quantity of water in the reservoir at the time. One hour after the water is released, the quantity of water is reservoir A is 1 1/2 times the quantity of water in reservoir Bdot After how many hours do both the reservoirs have the same quantity of water?

Two vessels have different base area. They are filled with water to the same height. If the amount of water in one be 4 times that in the other, then the ratio of pressure on their bottom will be

From the two points on the same straight line with the foot of a tower the angles of elevation of the top of the tower are complementary. If the distance of the two points from the foot of the tower are 9 metre and 16 metre and the two points lie on the same side of the tower, then find the hegiht of the tower.
