Answer:
Resistivity of wire remains constant. As the length of wire gets doubled, the cross-sectional area will become half of its previous value because volume of wire remains constant. Hence, we can see that the new resistance is four times the previous resistance.

Answer:
When the length of a wire is decreased the resistivity and resistance will also be decreased as They are directly proportional with the length of the conductor.
Explanation:
This happens because now as the length of the wire has decreased the electrons will have to travel a shorter path and rate of collapsing with atoms will also decrease as the path is short.
