A student measures the length of a spring. They then attach different weights to the spring and measure its length for each weight.
The table shows their results:
| Weight / N\text{N}N | Length / mm\text{mm}mm |
|---|---|
| 0 | 180 |
| 1.0 | 185 |
| 2.0 | 191 |
| 3.0 | 196 |
| 4.0 | 202 |
| 5.0 | 207 |
What is the extension of the spring with a weight of 3.0 N attached to it?
