To solve the question regarding the difference in resistivities of two wires made of the same material but with different lengths and areas of cross-section, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Resistivity**: - Resistivity (ρ) is a property of a material that quantifies how strongly it resists the flow of electric current. It is defined as the resistance of a uniform material of unit length and unit cross-sectional area. 2. **Resistance Formula**: ...
