Final answer:
The resistance of a copper wire can be calculated using the resistivity, length, and cross-sectional area, but the diameter of the wire is essential for this calculation and is missing from the provided information.
Step-by-step explanation:
The resistance of a copper wire depends on its resistivity, length, and cross-sectional area. The resistivity (ρ) of copper at 20°C is approximately 1.68 x 10-8 Ω·m. To find the resistance (R), we use the formula R = ρL/A where L is the length of the wire and A is the cross-sectional area.
For a cylindrical wire, the cross-sectional area A can be found using the formula A = π(d/2)2, where d is the diameter of the wire. However, since the given information does not provide the diameter of the wire in question, we cannot calculate its resistance without this crucial piece of information.
In order to proceed with the calculation, we need the correct diameter of the copper wire. If we had the diameter, we could calculate the resistance using the formulas provided above for any given length of said wire.
