The deligne dam on the cayley river is built so that the wall facing the water is shaped like the region above the curve y = 0.3 x 2 y=0.3x2 and below the line y = 120 y=120. (here, distances are measured in meters.) the water level is 30 30 meters below the top of the dam. find the force (in newtons) exerted on the dam by water pressure. (water has a density of 1000 kg m 3 1000kgm3, and the acceleration of gravity is 9.8 m sec 2 9.8msec2 .)

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
