Question 33

A student investigates the extension of a silicone strap when masses are suspended from it.

Identify the three additional items of apparatus from the list below that the student must use to carry out this investigation (assume they already have the silicone strap and the masses):

Ammeter
Clamp stand and boss head
Metre rule
Micrometer screw gauge
Weight hanger
Stopwatch

[3]

The table below shows the student's results:

Mass in $g\text{g}$	Force in $N\text{N}$	Extension in $mm\text{mm}$
$0$	$0$	$0.0$
$150$	$1.5$	$2.0$
$300$	$3.0$	$5.0$
$450$	Missing	$9.5$
$600$	$6.0$	$15.5$
$750$	$7.5$	$23.0$

State the value of the missing force in the table.

[1]

Describe how the extension of the silicone strap changes as the force increases.

[1]

Explain whether the silicone strap obeys Hooke's Law.
