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
Criticise the recording of these results.

, 2 A student made measurements to determine if some gold coins were made from pure
gold. The coins that were available to the student are shown below.
(Source: © Bjoern Wylezich/Shutterstock)
(a) The student used digital calipers to measure the thickness t and the diameter d of
one of the coins.
(i) Calculate the volume V of the coin, and the percentage uncertainty in V.
t = 1.54 mm
d = 22.16 mm
