Part J

The current in a certain wire at $20\mathrm{.}0$C$$C is $2\mathrm{.}40$ AA when the potential difference between the ends of the wire is $1\mathrm{.}50$ VV$.$ If the wire is heated to $80\mathrm{.}0$C$$C and the potential difference remains the same, the current decreases to $2\mathrm{.}00$ AA$.$ What is the resistance of the wire at $20\mathrm{.}0$C$$C$?$
