Answer all question

1 A student carries out an experiment to investigate the relationship between theextension, e, of a spring and the mass of its load, m. The apparatus is set up asshown in Diagram 1.1. The original length of the spring, lo is shown inDiagram 1.2.

The load of 50 g is hung from the end of the spring. The length of spring, l ismeasured by using a metre rule. The procedure of the experiment is repeated byusing mass, m = 100g, 150g, 200g and 250g.

Diagram 1.3, 1.4, 1.5 and 1.6 show the actual corresponding readings of thelength of spring, l.

(a) For the experiment described above, identify:

(i) The manipulated variable

(ii) The responding variable

……………………………………………………………………………[ 1 mark ]

(iii) The constant variable
