(a) State two errors in the student's measurement of the length of wire.
[2]
The student records the length of the wire as 12.8 cm.
[E]
The student is asked to measure the thickness of the wire using a pencil and the
same rule. Suggest how this can be done as accurately as possible.
[4]
(b) The student finds out that the density of the wire is 2.7 g/cm³. Express 2.7 g/cm³ in
kg/m³.
