Yes, in concentrated solutions (say >1M), chlorine ions get oxisided to form Chlorine Gas Cl2 (g)

IPT - just review the course and focus on ur extended responses, practise them and just keep practising (even if you only do one a day, cause its really boring lol) English - Write an essay a day

lol What I an askign is what the difference is between an essay that gets 18/20 and an essay that gets 20/20. I mean how do they discriminate between the two if they are both band six, is it just flair in writing, more content, or somethign else?

Is there some sort of thing I am doing wrong in my english essays, because the most I can ever get is 18/20 for anything written in exam conditions. I can get full marks when we have to hand in the essay, but never full marks in exam conditions. Considering that the second paper is basically...

If you put in the work there's no reason why you cant get a UAI of 90+ . Please read the hundreds of other similar threads on this issue ;) But it all depends (now) on how well you do in your HSC.

I did the paper and got 86 %, I'm pretty happy, too many silly mistakes though, like 2 -1/2 suddenly became 1/2 lol. I had no idea with that last binomial question though I'm not sure if we are allowed to post the paper but msg me on msn if u know what I mean ;)

I got 95%, it was the neap trial. Somehow it was easy this year :D

I would be jumping up adn down in joy If I had done the paper. And no, i don't think its illegal..

Vertical = Uy is U Sin15 Horizontal is Ux Cos15 Max height occurs when Usin15 = 0 (i.e. when vertical velocity = 0 ) 0 = USin15 + (-9.8)t 9.8t = USin15 You also know that range is 7 m X = Uxt 7 = Uxt .: t = 7/Ux This is the total time of flight. Max height occurs at half of the...

oh right, yep, sorry i didnt fully understand ur first point. Anyway me mate chan solved it above :D

I still dont understand why they would want you out of the class still..??

With uts it depends on the courses. They really want to get people into engineering, I know that, but I dunno about journalism.

Hey mate u want to do nano technology too :D I want do do that as well, at UTS, I'll probably be seeing you there next year

lol yeah, i just skipped to the n=k+1 step. Technically it shold start off with n=3, then assume true for n=k and then my step (prove true for n=k+1). Just add the first two steps and then its true by mathematical induction...

I dunno if this is right but could you do this? n=k+1 Need to prove (k+1)3 - 2(k+1)2 -(k+1) >0 LHS = (k+1)((k+1)2-2(k+1) -1) = (k+1)((k2 + 2k +1) - 2k -2 -1) = (k+1)((k2 -2)) but k>2 so (k+1)>0..and k2 -2 >0 when k>2 also (draw a parabola and this becomes clear) .: LHS = (k+1)((k2...

2) for this just derive the formula for maximum height, find then find velocity using that formula and u can then find t, time to go up. mutliplt that by two and use @ = 45 degrees and sub into the formula for maxumum range, i.e. R = V^2 sin2@/g (derive this as well)

1) for vertical motion: a = -g v = -gt + Vsin@ 0 = -10(4) +45sin@ 40= 45sin@ therefore @ = sin^-1 (8/9)

Just stick to 2 unit is my advice, dont do terribe in all ur tests because if they still dont let you into general then you will get horrible marks

You guys have obviously taken the quote out of context. Here is what timmy said If the homework is not relevant, theres no point in doing it is there?

It makes you write neater no really, it does
