A wire of resistivity is stretched to double its length. What will be its new resistivity?

Explanation

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**:
...
