# Multiple choice questions

Multiple choice questions are perhaps the easiest to complete - you simply put a cross in a box - however, the questions often have two answers that could, at first glance, be correct. Don't make the mistake of reading the first answer and thinking this is correct without checking all the others.

If it says 'Tick one box', you must tick one box. If you leave it blank or tick two or more boxes, you will get zero marks. These multiple choice questions will not start with command words like 'describe' or 'explain'. They will be written in the form of a question like 'What…?' or 'Why…?'.

There will be more multiple choice questions on the Foundation paper.

## Sample question 1 - Foundation and Higher

Question

This diagram shows the energy transferred by an electric heater in one second:

How much energy is wasted each second? [1 mark]

Tick one box.

A 12 J 38 J 50 J 88 J
A B 12 J ✔ 38 J 50 J 88 J

Calculation: 50 - 38 = 12 J

## Sample question 2 - Foundation and Higher

Question

Some students investigate a model of the craters produced by meteorite impacts. They drop balls into a tray filled with sand. They use six balls with different masses. They drop each ball from the same height.

Which one of these graphs shows the relationship between the gravitational potential energy (gpe) of the balls and their mass when they are all at the same height? [1 mark]

Graph A [1]

gravitational potential energy = mass × gravitational field strength × height

Gravitational potential energy is directly proportional to mass (when g and h are constant). This results in a straight-line graph through the origin.
