The graph illustrates how extension changes with force for a sample of rubber. The upper line shows how extension varies as force is applied. The lower line shows how extension varies as the force is removed. What does the area between the two lines represent?
- Athe work done as the force is applied
- Bthe work done as the force is applied minus the work done as the force is removed
- Cthe work done as the force is removed
- Dthe work done as the force is removed plus the work done as the force is applied
