It's a syllabus requirement to be able to solve all the problems they can throw at ya with the above 3 equations, btw...

Actually, I won't bet on questions not appearing this year because they appeared last year. Look at some of our english questions and etc, they may be scum and ask again.

When you draw graphs, you have an x horizontal axis and a y vertical axis. That is the cartesian plane. A cartesian equation is just an equation linking x to y e.g. y = x^2 y = 2x + 3 x^2 + y^2 = 4

hahaha...anyways i just asked that because i reckon it's a cliche term - it's overused and not well understood. So in almost all the schools they say they aim for "excellence", which is basically saying nothing much. But, lets bring economics into this. Without external competition, can...

Dumbarse, forget the other question bout inelastic electron collision. It's WAAY outside syllabus Anyway W = qV = 1.6 *10^-19 * 5.00 * 10^3 = 8 * 10^-16 This work energy is pure kinetic energy. 1/2 mv^2 = 8 * 10^-16 mass of electron = 9.019 * 10^-31 v^2 = 1.77 * 10^15 v = 4.21 *...

Where's the option that goes: "I hate them all"?

You've just proven my point. You don't know anything about me...

Oh, so you're different in the real world aye? Hard to believe... A name like "Stop Booting Me" really tells us how desperate you are to write something in this forum. Seems you're one desperate attention seeker... ...hmm...getting bored of baggin out sourie now...this is so repetitive...

I think V = Ed and W = qV (this is just the definition of electric potential, and we learnt this in our preliminary course) - one joule of work is done to move one coulomb of charge against one volt of potential difference. and E = -13.6 eV/ n^2 only applies to the hydrogen atom, and is...

Yup, everything's good to know... you would've needed to use the energy levels equation (Balmer's eqn), but since you've given me the wavelength, we skipped that step

i) E = hf = hc/lambda You should now have E in joules ii) W = qV V = W/q W is energy from (i), q is charge of electron

can someone define "excellence"?

Relive the nightmare? Hell no! :evilwhip:

No No NO! Don't burn it. Auction it to the highest bidder. There's a booming market in "Used HSC notes" Better still, keep it and start giving tuition @ ripoff prices. Your UAI will play an important role in how much you can charge, of course higher qualifications fetch higher...

med @ UNSW first then actuarial studies + something dbldegree @ Mac second...

And that "someone" is often VERY VERY far away...?

Actually, no one ever uses exam papers as firewood. Besides, people still used firewood a 100 years ago, if I recall correctly. You're really crap at history, Sourie, get YOUR facts right. dont type here ever again until you know a bit more about the world!

Don't you know what an empirical formula is?

I reckon you should aim for 100.05 UAI just like some of the ruse ppl do...

The first time I saw "Ideas to Implementation" as a physics topic i thought: WTF?? There was no possible way to figure out what exactly it was, until you read the content. Like, you could have "Ideas to Implementation" as a topic in ANY of the science subjects, if not in humanities or...
