Two rows of fluorescent lamps are installed in an office on the same branch circuit, with each row drawing 12.5 amperes. the source voltage is 277 volts, and the line or total circuit resistance is 0.5 ω. the wire used has a constant (k) of 12.6. what is the voltage at the load? (round the final answer to one decimal place.)

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.
