If the length of a wire is doubled, does its Young's modulus change ? Explain.

Explanation

To determine whether the Young's modulus of a wire changes when its length is doubled, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Young's Modulus**:
Young's modulus (Y) is defined as the ratio of stress to strain in a material. It is given by the formula:
\[
Y = \frac{\text{Stress}}{\text{Strain}}
