Does anyone know what mark (HSC, internal and external) was needed for a state rank in economics? All help is appreciated.

re: HSC Physics Marathon Archive I think it would be something along these lines - Scientists did not know the medium of travel for light (other waves had a medium so logically light, being a wave, was also thought to have one) observation and problem raised - The aether was the...

From 9c0(1+x)^9, the coefficient of x^2 = 9c0*9c2 (9c2 is the coefficient of x^2 in the expansion of (1+x)^9). Similarly, the coefficient of x^2 in 9c1(1+x)^8kx^2 = 9c0 which you multiply by 9c1, giving 9co * 9c1.

Re: HSC 2015 3U Marathon Could you explain your part (iii)?

re: HSC Physics Marathon Archive Analyse and assess Pauli's and Heisenburg's contribution to atomic theory. (7 marks)

Thanks for clarifying. I was confused because OP had it as sin(pi/2+x)=-cosx

How did you go from sin(pi/2+x) to -cosx?

Would a 71 align to 85, considering the test was easier than previous years?

Do they give you the (raw) marks section by section, or do you have to request it?

But that's taking into account the entire state. Now there's some not so bright students.

What did you write about? That seems well over 4000 words, so more than 2000 words per essay.

When I say repay in some way or another, I meant that the receiving country must pay back either through increased trade with the providing country or by allowing greater financial flows into that country, not by repaying the aid itself. I can see your point though. I guess it is entirely up...

To my understanding "conditional" means it is tied aid, which means that the recipient must pay back the provider in some way or another. If this was the case, then it would be recorded on the capital account since then it would be reversible. Building a school does not entail a 'paying back the...

Funds to build a school is in no way conditional. Being unconditional, it should be a non-reversible transaction on the net secondary income account (ie. a debit).

The key words here is "all other things being equal", which implies that the exchange rate doesn't change. Hence C is the most correct answer here.
