A150 kg object and a 450 kg object are separated by 0.430 m. (a) find the net gravitational force exerted by these objects on a 39.0 kg object placed midway between them.

How is the gravitational force related to the distance between two objects?

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.

The energy produced as a result of this flow of electrons from atom to atom is called
