Calculate the resistivity of the material of a wire 1.0 m lomg, 0.4 mm diameter and having a resistance of 2.0 ohm.

Explanation

To calculate the resistivity of the material of a wire, we can use the formula for resistance:

\[ R = \frac{\rho L}{A} \]

Where:
- \( R \) is the resistance (in ohms)
- \( \rho \) is the resistivity (in ohm-meters)
- \( L \) is the length of the wire (in meters)
