Answer :
Answer:
R = 0.14 Ω
Explanation:
The resistance of a metal is given by the relation
R = [tex]\rho \frac{L}{A}[/tex]
where ρ the resistivity is 5.6 10-8 Ω m, they also give the length and the cross section (area)
Let's reduce the magnitudes to the SI system
L = 200cm (1m / 100cm) = 2.00m
A = 8.0 10⁻⁷ m²
let's calculate
R = 5.6 10⁻⁸ [tex]\frac{2.00}{8.0 \ 10^{-7} }[/tex]
R = 1.4 10⁻¹ Ω
R = 0.14 Ω
