what is the magnitude of the gravitational force on mass m? express your answer in terms of the variables m, m, l, d, and the universal constant g.

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)

How is zig zagging a form of acceleration?

If an electric circuit is not grounded it is best to reach out and touch it to provide the ground a.true or b.false
