hmm, so if I dropped economics it wouldn't disadvantage me in commerce? is business studies helpful in this course? (I don't do business studies)

Hi, economics is probably my worst subject besides english and I'm hoping to drop it by next term. My question is, does the bachelor of commerce have anything to do with economics and would it help? Can you also briefly go over what the bachelor of commerce involves? Edit: I'm hoping to go to...

wow :s, u sure 40% for half yearlies? their normally only 10-20.

yup, this sounds right

good luck with this :), haha nice way of recording progress Random quote: "losers discuss why they can't "

The third one is most correct, "getting a mark that the board of studies suggests is suitable for a band 6, by scaling subjects against each other.", it's determined by scaling and is done by BOS and I don't believe the whole procedure of how scaling works is released to the public. The...

hm, should be cos3x not tan :)

How would you go about this question? Given: The mass of the satellite is 10 000kg mass of the earth is 6x10 ^24 distance from the centre of earth to satellite is 581310.94 +6373000 Question: How much work would be required to move the satellite from its altitude to a point where...

Is the formula v=rw required in the hsc? I just saw a question using this formula and did not recall learning it.

damn, I stuffed up an earlier part of the question.. forget about the first one then =S, assumed it was right cause I tried k=2 and it worked, but when I tried k=3 it didn't soo yeahh silly me.

can anyone help with Q ?

I've already closed the Latex editor :( test^3 edit: cool it works I'll try that for next time, thnx Trebla.

Hi guys, I'm stuck on two questions for proofs. Please help :) How would you prove that the left hand side is equal to the right hand side of the equation? These are where I'm at in proving some mathematical induction results. 2)...

Don't do it, do it next year :) I suggest you read over the prelim material this year (from textbooks and such), then next year get a tutor for HSC physics to consolidate your learning.

thanks :), the min t.p for the multiple choice wouldn't be on y=0 right? how do you know this?

Hi can someone explain this MC to me please? Having a bit of trouble, how do you manipulate it? so do you think of the graph as a cubic and integrate it so thus it's a quartic now? then what :s? Also, if f(x) = x - 4/x how would you do e^f(x) and ln(f(x)), when I tried them I got completely...

Re: 2013 HSC physics marathon All Low Earth Orbit (LEO) satellites will eventually fall to the Earth's surface due to atmospheric drag. Because LEOs are typically 160-2000km above the surface of the Earth, the satellite tends to collide with air molecules, this creates friction and thus...

Not sure what you mean =S Would it be because the circuit of the coil is not complete thus eddy currents cannot be formed (or minuscule amounts) to oppose the force of the magnetic field?

Please explain why answer is D, thanks =). Does this come under the topic motors and generators?

So it's just the angle between the plane of the current and the magnetic field? If it is I think I understand.
