I'm fairly sure quite a few people will have this clash. I want to see if we can get enough people from here to contact them about it :)
To me it seems a bit stupid for them to have 2 lectures on AMME2500 at different times on the same day.
Anyway, if you have this clash, post here and let...
wooooo
AMME 1060 Engineering Applications 92.0 High Distinction
ENGG 1803 Professional Engineering 1 87.0 High Distinction
MATH 1003 Integral Calculus and Modelling 68.0 Credit
MATH 1005 Statistics 73.0 Credit
PHYS 1902 Physics 1B (Advanced) 86.0 High Distinction
maths sucks.
There are big debates about whether commerce is better at usyd than at unsw. I don't think there was any conclusion reached.
As for engo, they are both probably the same. It just comes down to what subjects you are interested in (UNSW may offer some that sydney doesn't) but the core subjects...
Dude, there is plenty of evidence for the standard model.
There are a lot of fringe groups in science who think general relativity is wrong too, but that doesn't mean you should forget about it.
I think they might be referring to the right hand set rule (is that what it's called)?
For point charges moving through magnetic fields and so on, you can predict the direction in which the force will act. I think thats the only thing to do with vectors that you touch on in the HSC.
I did the HSC last year, and if i can remember correctly, no you don't need to know how transistors or diodes work in any great detail. Just know what P and N type doping is...
They aren't asking you to write a literary masterpiece. All you have to do is communicate effectively.
If you can't do that then you better learn fast or you will be next to useless to employers or in further education.
The number of marks is the best indication of how much to write.
As for what to write, make sure you read the question. Usually you can pick up at least 3 points from the question to write about. Include any relevent laws (Cons of energy/Faradays law/whatever) and equations, and background...
Dude!
For the height of the tower, E = mgh will suffice.
At the bottom of the tower the E = 1/2 * m * v^2.
All of this KE is converted into GPE, so
GPE (at the top) = KE (at the bottom):
mgh = .5mv^2
h = (.5 * v^2) / g (the masses cancel)
I'll let you sub in the numbers...
Everything in classical mechanics comes back to the good old 2nd law of newton:
F = m*a
More generally, it can be said that the sum of the forces acting on a body will result in an accelleration.
Now on a car moving along the ground you have several forces acting - weight, friction...
Technically your answer to part A is only accurate to the least number of significant figures they give you in the data. So say if they gave you g = 9.81 and this was the number with the least sig figs, it would be all you could give your answer to (ie 3 sig fig). You would then use this answer...
The real aero industry is overseas. If you end up doing aero expect to move overseas at some point in your career, as most of the jobs in australia are maintenance style jobs.
