Answer:
energy? or power? I'm not really sure but using the quizzes app really help with science problems
<span>Antimony I am pretty sure is one. </span>
Ok so I already studied this and I realized it was water or also Oxygen
The resistance of the piece of wire is

where

is the resistivity of the copper

is the length of the piece of wire

is the cross sectional area of the wire
By substituting these values, we find the value of R:

Then, by using Ohm's law, we find the potential difference between the two points of the wire:
