Consider a power plant located 25 km outside a town delivering 50 mw of power to the town. the transmission lines are made of aluminum cables with a 7cm2 cross-sectional area. find the loss of power in the transmission lines if it is transmitted at (a) 200 kv (rms) and (b) 120 v (rms).

During the apollo moon missions, astronauts were concerned about the effects of newton's third law of motion when: o a. they ejected waste water, because they were concerned that it would push them off course. o b. they reentered earth's atmosphere, because they were carrying heavy moon rocks. o c. they took off from earth, because a large force was required to generate large acceleration. o d. they detected incoming space debris, because the inertia of the debris could damage their ship.
