Answer:
It is given that power = 5000 W for 120 V and resistance is per 1000 ft of wire. The wire is 750 ft away from 120 V source. We need find the voltage delivered to this load.
Resistance of 750 ft wire, =
Using Ohm's Law:
Voltage delivered to the load,

I believe the correct answer would be "A" energy source.
Answer:
No
Explanation:
Unless there are other external forces, this will never be true. Because according to energy conservation, potential energy will be converted to kinetic energy as the ball falls down (so it loses height and gain speed). And vice versa, kinetic to potential when it bounces back. So the potential energy after must be the same (or smaller if losing heat to external environment), so it can only get the the same height or less, but not more.
