You are given three pieces of wire that have different shapes (dimensions). you connect each piece of wire separately to a battery. the first piece has a length l and cross-sectional area a. the second is twice as long as the first, but has the same thickness. the third is the same length as the first, but has twice the cross-sectional area. rank the wires in order of which carries the most current (has the lowest resistance) when connected to batteries with the same voltage difference. rank the wires from most current (least resistance) to least current (most resistance).

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
