A student investigated the stretching of a spring by hanging various weights from it and measuring the corresponding extensions. The results are shown in the table below:

mm01631626379\begin{array}{|l|c|c|c|c|c|c|} \hline \text{Weight / N} & 0 & 2 & 4 & 6 & 8 & 10 \\ \hline \text{Extension / mm} & 0 & 16 & 31 & 62 & 63 & 79 \\ \hline \end{array}

One of the recorded results appears to contain an experimental error. Identify this anomalous result.

Excluding the anomalous result, state and explain whether this spring obeys Hooke's Law.

Describe how the shape of a graph of extension against weight would change if the student continued to add many more weights well beyond $N10\text{ N}$ .

The student estimates that if they hang a $N40\text{ N}$ load on the spring, the extension will be approximately $mm320\text{ mm}$ . Explain why this estimate may be unrealistic.
