Afisherman has caught a very large, 5.0kg fish from a dock that is 2.0m above the water. he is using lightweightfishing line that willbreak under a tension of 54n or more. he is eager to the fish to the dock in the shortest time possible. if the fish is at rest at the water's surface, what is the least amount of time in which the fisherman can raise the fish to the dock without losing it?

If a simple machine reduces the strength of a force, what must be increased?

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg
