Answer:

Explanation:

Resistance is directly proportional to the length of the wire, and inversely proportional to the cross sectional area of the wire. ... Doubling the length will double the resistance, but the wire also must get thinner as it is stretched, because it will contain the same amount of metal in twice the length.
