Inquiry 1: Exploring and designing

State why the experiment is repeated with different values of $W$.

The measurements of $T$ were collected five times. Explain how repeated measurements of $T$ reduced the random error in the final experimental value of $mr$.

Outline why repeated measurements of $T$ would not reduce any systematic error in $T$.

There is an advantage and a disadvantage in using two masses that are almost equal.

State and explain the disadvantage with reference to your answer to (a)(ii).

The mixture was held in a large metal container during the mixing.

Explain one change to the procedure that will reduce the difference in (b)(i).
