A uniform copper wire of mass `2.23xx10^(-3)` kg carries a current of 1 A when 1.7 V is applied across it. Calculate its length and area of cross-section. If the wire is uniformly stretched to double its length, calculate the new resistance. Density of copper is `8.92xx10^(3) kg m^(-3)` and resistivity is `1.7xx10^(-8) Omega` m.
