1 A student stretched a length of nylon fishing line using the apparatus shown below.
wooden blocks
G-clamp
pulley
nylon fishing line
mass holder
and masses
metre rule
(a) The nylon fishing line was stretched by adding masses to the mass holder. The
positions of the bottom of the mass holder were measured as masses were added.
For each mass, the extension of the nylon fishing line was calculated.
The student recorded the results, as shown in the table.
Mass / kg Extension / cm
0.05 0.4
0.1 0.8
0.25 2.1
0.5 3.9
0.75 6.0
1.0 7.2
