In this experiment, a student records measurements and finds the extension of a spring for a range of loads. The arrangement is shown in Fig. 2.1. The results are given in the table in Fig. 2.2.
(a)[1]
The table includes only some of the extensions. Complete it so that every extension is shown.
(b)[2]
Calculate the load that gives an extension of 49 mm.
(c(i))[1]
Put ticks (✓) in the boxes to show how the value of each energy form at A compares with that at B.
(c(ii))[2]
The student does work while pulling the load down. The law of conservation of energy says that energy cannot be created and cannot be destroyed. Explain how this principle applies in this case.
