Oh, ok. I always thought there was...

Not entirely calculus based, but certainly mathematical. I think the board should do what they used to, and have a 2 unit and a 3 unit physics course, with the 3 unit course being the more demanding mathematically. They could make 3 unit maths a requirement for the 3 unit physics course if it...

Yeah. Certainly, its very interesting...

Don't expect HSC physics to help you in uni. Apart from a little bit of background in year 11, I found year 12 physics a total waste of time in that it hasnt helped me one bit yet in uni physics - uni physics is much, much more mathematical. Mind you, that is just my experience so far...

(a) Use the momentum formula, m1u1 + m2u2 = m1v1 + m2v2 (b) If Kinetic energy is conserved then the collision is elastic. Hence use the Kinetic energy formula.

The equations for energy you use above are low-velocity approximations, and do not apply when speeds are very large.

Yeah, we don't get a cert. The lesson here is to aim for number one, and if you don't reach it, make sure u don't reach it by about 19 places.

Whatever u do don't get second in the state. You get nothing (not even a certificate)

This is in the camrbdige 2 unit book, for small angles sin @ = approximately @ . But it does look like a 3 unit question.

That is true. But if people want to do it that way, and it assists understanding, then why not

Its not so much your mark that matters. What you learn matters - I think some degrees assume that you are competent at 2 unit maths. You could always do a bridging course if you wish, but of course you will be a bit behind most ppl undertaking that degree in terms of mathematical ability if you...

what's inertial force??? (inertia is not a force)

You need to indicate the numbers as many times as they appear. So for your example it would be 1,1-dichloro-2,2-dimethylpropane : no dashes in between words, only between words and numbers.

The question is badly written. There was a big debate about it last year. You can view what ppl had to say about it here: Long story short, forget about the question. http://community.boredofstudies.org/17/chemistry/81124/cssa-results/3.html?highlight=oyster Link edited. Sorry, should have...

There's no need to stress for IPT, ;) . You don't have to go too in depth. Try a few past paper questions, you will see that there are a few things that always pop up (like network topoligies), so make sure you study those.

Try and get a mark in the 80's for bio...

Bring up your bio mark and you should be able to get 80. There's still plenty of time till the hsc.

I have two fee statements for semester two as well. Apparently the admin is having a problem not knowing how to delete the statments - just pay your most recent statement is my advice.
