Ummm...my best answer is that heat helps the molecules move around faster and that temperature is the measure of that heat or cold.
<span>The answer is D. Electric resistance increases with an increase in the length of a wire and as a result current flow decreases. There is a direct relationship between the length of the wire and the resistance. The longer the wire, the more resistance there will be. Additionally, from Ohm's Law, current is inversely proportional to resistance. This means as the current increases, resistance decreases or vice versa.</span>
Cell phones use RF waves from nearby cell towers. RF waves fall in between FM radio waves and microwaves
