    i think i got 0.0675%?

    Serious question

    I couldn't remember whether blue light had higher frequency or not. I was trying to remember a graph type picture of the electromagnetic spectrum and just went with blue having a higher frequency, got a bit lucky on that one.

    Part B?

    I used this as well and got the right answer. The answer was posted earlier in the thread, it was somewhere in the 7000s.

    General Thoughts: Physics

    does anyone remember a question that asked about the maximum torque on something? I can vaguely remember it but not really. If someone had an answer it might ring a bell.

    Part B?

    The answer was 7692m/s. Someone put up what the radius and mass was earlier in this thread. Find the values in this thread and go back through the method and see if you got the right answer. If you got the right answer then i don't see why you wouldn't get full marks.

    I thought it was a CAT scan??? There is a dot point that says, students: - gather secondary information to observe a CAT scan image and compare the information provided by CAT scans to that provided by an X-ray for the same body part. The dot point seems to match the question pretty well. I...

    Part B?

    yep it got the right answer. Silly of me going the long way round though hah. I'm just relieved i didn't lose a couple easy marks.

    Part B?

    I think i found what the period was by r^3/T^2 = GM/4pi^2 and then solved v with V = 2rpi/t Is this wrong because i assumed its orbit as a circle? I think i overcomplicated this one, easy marks lost if i did.

    cool. I talked about half lifes, decaying by positron emission, how they can be tagged to metabolic vessels like glucose to circulate in body.

    Part B?

    What was the method of working out the orbital velocity question. I can't remember my answer but if i see the method i will know if i got it right or not because i remember how i did it. I can hardly remember anything from part B.

    What points did you guys make for the 6 marker?

    This is what i did.

    Medical Physics Option

    Who did medical physics and how did you find it? I think i may have managed full marks or at least close to it (touch wood), i wrote loads and am pretty sure i didn't leave anything out. The questions were really straight forward for med phys and the whole paper in general i thought.

    band 6 cut-off.

    I reckon 78ish. I don't think it will reach 80 but it was an easier paper this year so who knows.

    Dammit i lost a mark on this one. I remember thinking exactly what you said that it contracts in the direction it moves. And i thought of the train in Einstein's thought experiment and how it contracts, and then i picked C. Oh well, looking at the other answers here i still did well.

    how much did you write?

    a patota Same here. I just wrote a smaller so i could fit plenty of info in.

    how much did you write?

    didn't fill the lines? 2 marks deducted straight away.

    how much did you write?

    Just filled the page on the 6 marker for AC generator, a bit below the lines too, but i write pretty small. I don't do quanta to quarks but i wrote around a page and a half for the 6 marker in med physics.

    Mine look fairly similar with a couple different. Unlucky on question 19, i put C at first and quickly realised my mistake thank fuck haha. Pretty sure your number 7 is right, unless i can't use a calculator either.
