a. When resistance is cut into two equal parts, then it becomes two resistors in the series. While substituting this in heat equation- the heat energy will double.
b. Heating the metal conductor causes atoms to vibrate more, which in turn makes it more difficult for the electrons to flow, increasing the resistance. Heating the wire increases resistivity.
I hope you found my answer helpful !!!
