A student investigates how the length of a spring changes when she hangs weights on it.
The Table shows her results.
Table
| Weight in N\text{N}N | Length of spring in cm\text{cm}cm | Extension in cm\text{cm}cm |
|---|---|---|
| 0 | 4.0 | 0.0 |
| 1.0 | 6.0 | 2.0 |
| 2.0 | 8.0 | |
| 3.0 | 10.4 | 6.4 |
| 4.0 | 12.0 | 8.0 |
| 5.0 | 10.0 |
Complete the Table.
Identify the anomalous result in the Table.
Give a reason for your answer.
Calculate the spring constant of the spring in N/m\text{N/m}N/m.
The student adds more weights. When the weight is 9.0 N, the extension of the spring is 24 cm.
Explain what this result shows about the spring.
