The resistance R of a wire of length l and uniform area of cross-section A is given by R = rhol/A, where rho is the resistivity of the wire. You melt the wire and recast it to have a new length l' = 10l (keeping the volume V = Al of the wire constant). What is the new resistance of the wire, if the original resistance of the wire was 100.0 Ohm.

Six
copper wires have the lengths and cross-sectional areas listed
below. The resistance R of each segment can be calculated using, R
= pL/ A
Where p is the resistivity, L is the length of the wire, and A
is the wire's cross-sectional area. Rank the resistances of the
wires from lowest to highest.
