Ac generator provides emf to a resistive load in a remote factory over a two-cable transmission line. at the factory a step-down transformer reduces the voltage from its transmission-line value to a much lower value that is safe and convenient for use in the factory. the transmission line resistance is 0.3 w per cable, and the power of the generator is 250,000 w (rms).1 if (rms), what are

(a) the voltage drop dv across the transmission line,
(b) the rate at which energy is dissipated in the line as thermal energy?
(c) if instead were 8000 v (rms), what would be the voltage drop and power dissipated in the transmission line?
(d) repeat part c for (rms)

Two identical small charged spheres are a certain distance apart, and each one initially experiences an electrostatic force of magnitude f due to the other. with time, charge gradually leaks off of both spheres. when each of the spheres has lost half its initial charge, the magnitude of the electrostatic force will be

How have the competing explanations' experiments on atoms affected the development of the atomic model?

How do the measurements of charge at the different locations on the sphere compare to each other? the charge measurements are different at all locations on the sphere. the charge measurements are virtually not the same at all locations on the sphere except for the charge at the very top and at the very bottom that are equal. the charge measurements are virtually the same at all locations on the sphere except for the charge at the very top. at the top, the conductive sphere has a small disk that is made of different material. the charge measurements are the same at all locations on the sphere. what happens to the charge on the conductive sphere when it is connected to a source of charge such as the electrostatic voltage source? nothing will happen because no charge goes around the surface of the sphere. the charge on the conductive sphere spreads out over the surface of the sphere; being greater in some specific locations on the sphere. the charge on the conductive sphere spreads out uniformly over the surface of the sphere. the charge on the conductive sphere spreads out non-uniformly over the surface of the sphere.
