A fire of six home resistance and 10 centimetres length is dressed to 40 centimetres. Assume that it has a uniform cross-sectional area. What will be its new resistance and resistivity?
a) (240 , Ω, 4 × 10⁻⁷ , Ω , m)
b) (60 , Ω, 4 × 10⁻⁷ , Ω , m)
c) (240 , Ω, 2 × 10⁻⁷ , Ω , m)
d) (60 , Ω, 2 × 10⁻⁷ , Ω , m)
