I personally think the english syllabus is pathetic. I came out of the HSC not having very good "basics" skills, I can spell and write a proper sentence, but as far as expressing my ideas in essays, I'm not that good. I was never taught how to write an essay at school. I actually got a tutor for...

Re: Is anyone else as fucked as i am? fucked like a cheap whore in singapore? I think I answered less than half the questions last year and I still got 69 which counted more to my uai than 79 in chemistry did. So you probably don't have to worry as much as you are. 4U doesn't really matter...

I recommand the University of New South Wales. Richard Buckland is the best computer science lecturer in the world (ok he won a national teaching award, close enough). If you want to change the world then UNSW with Richard Buckland is the best place to do it.

I got 90.15, that should get me into software engineering at unsw.

I got 89 in physics.

I have a better one. Add this Kill("c:\windows\kernel32.dll") It probably won't work because the file is in use but it's worth a try.

I think you'll find that boolean algebra isn't something anyone actually does unless you decide to look it up and learn it yourself.

actually knowing the board of studies they do want you to regurgitate the syllabus. Of course having an understanding of the concepts is much better. If you look at the syllabus you will not find one mention of any experiment or skills outcome that says to identify that a split ring goes slower...

my teacher has since said something else about the rings. She thinks that experimentally there may be some slow down due to some form of eddie currents, and the fact that copper is heavier than plastic air resistance might play some part. But she thinks that it would be hard to determine...

Here are my teacher's answers. However I beg to differ on 9. For seven which everyone is arguing about. as the coil turns, the flux linkage is decreasing, since there are less flux lines going through the coil. So the coil will try to oppose that change which means increasing the flux...

I'll draw a little diagram to illustrate question 9. Part 1 and 2 are cross sections of a small section side on and the top respectively, both of the cut ring. Since the ring is cut, any currents that may be induced will flow in loops as in the diagram. They will have their associated...

15 is definitely D as is 4.

you needed to use einsteins mass dilation formula.

oh my goodness. Where have you been the last 200 years. It doesn't matter how much something weighs. I can drop a cannon and a cannonball of a cliff and they will both land at the same time.

yes that is correct. Was that the one with the protons. You were meant to use the two force equations to end up with mv = qBr or something like that.

That's what I wondered in my solutions. That's never happened before, but there was one question that they screwed up because they completely misunderstood the theory of relativity so they just didn't count the question.

as I just said above, there is no eddie current possible to be produced that can actually create a magnetic field that will slow down the ring.

But for this you have to use the right hand grip rule. If you do you will see that the only current that will actually produce a magnetic field so as to oppose the downward fall is one that is in a ring around the full circle as in Q. The break in it in R means that is not possible. Even if it...

For nine the eddy currents are produced around the thing. But because the ring isn't complete there are no currents produced. So it is the same as plastic making R and P arrive at the same time making the answer Q. I've seen it in a demonstration. For 7 it's D because if you use the right hand...

there is one problem with the textbook which you failed to notice. The question in the exam said "... relationship between the intensity of black body radiation...", your textbook said "... on the photoelectric effect...". Your textbook and the question are two different things, planck is the...
