What energy transformations take place when you turn on a fan?

Current enters a circuit at a: 1.positive terminal 2.negative terminal 3.low potential side 4.resistor

According to newtons universal law of gravitation, which would change the parh of the ball so it traces out widest curved path possible?

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.
