I am confused about Resistivity. #25 to be exact. "For some applications, it is important that the value of a resistance not change with temperature. For example, suppose you made a 4.70-k (ohms) resistor from a carbon resistor to a Nichrome wire-round resistor connected together so the total resistance is the sum of their seperate resistances. What value should each of these resistors have (at 0degreesC) so that the combination is temperature independent?" Like for real? this is so confusing it like gibberish!

A 500-W heating coil designed to operate from 110V is made of Nichrome wire 0.500 mm in diameter.

Assuming the resistivity of the Nichrome remains constant at its 20.00C value, find the length of wire used.
