To solve the problem of determining the new resistivity of a wire that is stretched to double its length, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Definition of Resistivity**: Resistivity (ρ) is a material property that indicates how strongly a material opposes the flow of electric current. It is independent of the dimensions (length and cross-sectional area) of the wire. 2. **Identify the Initial Conditions**: ...
