Answer 2

The resistance of the wire is 0.01 ohms.

Step-by-step explanation:

It is known that $R = \rho\frac{l}{A}$

The values are: R = ?, resistivity = 2$\times 10^{-8}$ ohm/m, length, l = 1 m, and cross section, A = 2m$m^2$= 2$\times 10^{-6}m^2$

Substituting the values, we obtain

R = $\frac {2\times 10^{-8} \times 1 m}{2\times 10^{-6} m^2}$

R = 1$0^{-2}$ ohm

Thus, the resistance of the wire is 0.01 ohms.
