Kinetic energy because it's moving
Answer: If you use a very small resistance AND the circuit design is such that the voltage drop is across the resistance of the heating-wire-circuit, [nothing else in the circuit is limiting current flow] you will get more heating. That's what we have in a heat anticipator internal-nichrome-wire-heater device.
Explanation:
Answer:
due to production of heat through friction
It wouldn't indicate the same source if the paint was from a different place. If the paint was the same brand and color it would be but if not then no
Work = (500N)(15m)=7500J Power= (7500J)/(20s) =375 W
