Answer
Hooke's law states that the extension (increase in length) of an elastic object is directly proportional to the force applied.
Step 2
Plot a graph of extension (increase in length) against weight.

Answer
To plot the graph, use the data provided. Place weight (N) on the x-axis and extension (cm) on the y-axis. Ensure appropriate scales are used. The points should include the origin and the last three data points, and a line should be drawn connecting the points to illustrate the relationship.
Step 3
Use the graph to find the weight that would produce an extension of 5 cm in the spring.

Answer
From the graph, the weight that corresponds to an extension of 5 cm can be determined. It appears to lie close to 1.0 N, based on the graph's trend.
Step 4
Estimate, from your graph, the weight after the addition of which the law seems no longer to apply.

Answer
By examining the graph, it can be estimated that Hooke's law no longer applies after approximately 1.6 N, as the line begins to level off, indicating that the spring is not obeying the law after this point.
