Expert Answer:

Drift velocity is inversely proportional to the length for constant value of V potential difference. Thus, if the length of the conductor is doubled drift velocity will be halved.

            The resistance of conductor is directly proportional to the length of the conductor. Thus, if length is doubled resistance will also be doubled.

Resistance is directly proportional to R. Hence, if R increases Resistivity also increases.
