Speed as well as accuracy is important in this section. Work quickly, or you might not finish the paper. There are no penalties for incorrect responses, only marks for correct answers, so you should attempt all questions. Each question is worth one mark.
You must complete the answers within the time limit. Calculators are NOT permitted.
Good Luck!
Motion and forces
Image reference: http://hyperphysics.phy-astr.gsu.edu/hbase/Mechanics/motgraph.html
Explanation
The correct answer is C.
Of the statements the only one which can be supported by the graph is C.
Motion and forces
Image reference: http://hyperphysics.phy-astr.gsu.edu/hbase/Mechanics/motgraph.html
Explanation
The correct answer is B.
Using the graph candidates should be able to determine that answer B is correct.

Explanation
The correct answer is B.
Candidates should look at the graph for acceleration.
Motion and forces
Image reference: http://hyperphysics.phy-astr.gsu.edu/hbase/Mechanics/motgraph.html
Explanation
The correct answer is C.
Candidates should be able to use the graphs to reason that C is correct. Velocity is increasing, there is acceleration and a plateau is being approached.

Is the velocity not decreasing towards zero? After which it comes to a standstill. And the negative sign just implies that it is travelling in the opposite direction?
Explanation
The correct answer is D.

Joel, half-life is the time required for a quantity to reduce to half of its initial value. So, in this question the half-life for iodine-131 would be determined from 100% to 50% which is 8 days.

You can't answer this one with the graph?

The graph shows hours, not days. Therefore it's four days and the correct answer would be 10am.

How can this question be answered when the elapsed time is in days?

Agree with Chris! There are just too many errors in these questions, who came up with them??

The Answer is B if you substitute "days" for "hours" in the x axis. Poorly written question.
Waves
Explanation
The correct answer is C.
Violet light has the smallest wavelength and therefore the highest index of refraction. The higher the index of refraction the more the light bends and therefore the smaller the angle of refraction.

A lot of these questions are too easy

I'm confused, the question is "Which colour of the visible spectrum would have the smallest angle of refraction?" which is red? The explanation answers which has the highest index of refraction.

@Alex, the angle of refraction is relative to the normal line from the reflection interface. Red refracts the least when entering a medium so its angle to the normal line would be the largest. Because violet has the highest refractive index, it refracts more when entering the medium and therefore is "closer" to the normal line - it has a smaller angle of refraction.
Waves
Explanation
The correct answer is B.
Candidates should be able to immediately recognise the red flag language of always in answer B so even if they are unsure of this physics topic they should be able to identify the correct answer.

The answer and the explanation does not tally. The explanation warns of a "red flag" and that option is the answer?
Waves
Explanation
The correct answer is A.
This may be a tough question for candidates and they should think about what is more likely to cause light to bend.

If light is totally internally reflected then it does not travel from one medium to another. Answer A is incorrect.

This is not true. A change in velocity does not necessarily mean there is a change of acceleration. If velocity is increasing at a linear rate then acceleration is constant so then there is no change in acceleration but velocity is still increasing.
Sun, 27 Feb 2022 13:26:26
Agree with what Sam said.
Mon, 25 Apr 2022 19:27:23
C cannot be correct as at time 15 seconds there is a change in velocity with a constant acceleration. B should be correct as there is a positive relationship with a positive acceleration resulting in an increase in velocity.
