An 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 (rms) transmission value Vt to a much lower value that is safe and convenient for use in the factory. The transmission line resistance is 0.30 /cable, and the power of the generator is 250 kW. If Vt 80 kV, what are (a) the voltage decrease V along the transmission line and (b) the rate Pd at which energy is dissipated in the line as thermal energy
It appears to rise and set because of the Earth's rotation on its axis. It makes one complete turn every 24 hours. It turns toward the east. As the Earth rotates toward the east, it looks like the sun is moving west.
