At the same temperature, two wires made of pure copper have different resistances. the same voltage is applied at the ends of each wire. the wires may differ in check all that apply. view available hint(s) check all that apply.(a) length.(b) cross-sectional area.(c) resistivity.(d) amount of electric current passing through them.

(A) length.(B) cross-sectional area.

Explanation:

The two options that they could have different are the length and the cross sectional area, and that can make the have the different resitances the longer the wire the more resitance it will have, since they are made from the same material and the same voltage is applied ot them, neither C or D could be because the resistivity depends solely on the material with which things are made of and both are pure copper wires.
