Just a quick question. why did they have to turn the apparatus 90 degrees? If they've already split the light into 2 waves, one going across and one going against aether, wouldn't that give them the interference they needed? What good does turning it do? Wouldnt it mean that still 1 light in...

lol exactly. hsc science should be reviewed and changed completely likewise for 4u conics. who da fk need it!? you get computers to calculate these painful crap in uni (so i heard)

ASTON MARTIN DBS!!!!!! (though the new ferrari 458 italia could replace this)

physics and chemistry is definitely not hard. as long as you understand the topics + you can memorise the details, you'll do fine. a word in advance, start memorising the scientist's contributions and experiments as soon as you learn them. just speaking from experience here....during the...

i suppose it kinda depends on how good you are with the chosen subjects. if you are really good, then i suppose you can balance the time needed nicely. it doesnt matter really, since you are dropping 1 for hsc anyway. just make sure you know what to drop so you don't put too much effort in to...

i do all 3 so i think i can give you a rough view into all of them personally, i like bio the best because i'm interested in medicine and the yr 12 course has more to do with it than the prelim. its also the easiest imo (common sense mostly) i find that chem has more memorisation required than...

i'm still waiting on gt5...good thing it doesnt come out during hsc. too much of a distraction otherwise. definitely getting cod 6 though

any idea where i can get a pair? heard that they are very expensive though

rofl! w t h is that!!!! btw, any1 think cutner's death is just completely random? although the final scene was pretty good (house finally finding the photo)

any 1 watch it? its the only show I'm watching atm (w8ing for heroes etc to come bk) did it get axed by ten? i saw it before, it was season 1 i think if u do watch it, any1 think Michael's glasses r just awesome!

my school doesnt hav agriculture because, well, no 1 wants to do it... as for eco and japanese, eco is quite hard, takes up a lot of your time and you have to keep up to date with all the stats for your essay, thats y i dropped it for hsc. and japanese? i heard its a bludge...well not rly a...

true, especially when you did then long way, then you see the solution to the short way, you just go, ofcause! its so simple! y didnt i see that...

i like to do past papers. as many as possible and get your teacher's feedback. this way, i can find out which sections i need revising and how to answer questions better - win win :D reading other people's notes also help imo

i find that the best way to deal with circle geometry is to work backwards. what i mean by this is that when you see the question, you have to think to your self what rule will prove this. knowing what properties must prove makes it a lot easier imo. you can try turning the page around, just to...

hi guys. i'm using the rabbit proof fence (film) as a subtext to belonging. i'm wondering how i can analyse the aspect of family belonging in it. i'm finding it difficult to locate film techniques or quotes etc...

sorry k02033, i'm just really confused with physics at the moment. i think it would be best if i come back to this again with a fresher mind. thanks for your help.

how did hertz show that EMR is polar? i reckon the jacaranda book is just useless in this topic, they never really explain clearly how this or that works...

that's when you told me voltage is not potential difference... so voltage is electrical potential difference, and the pressure or push behind the electrons?

in the graph given by jacaranda (i don't know how to post images on here so ill just describe it...), the graph showed intensity vs wavelength. as the wavelength decrease towards zero, ie frequency increases, the intensity shoots up, hits a peak, then falls back down. i'm given to understand...

ok, i think i get it. but to be precise, what is the difference between potential difference and electrical potential difference. because at the beginning, u said that voltage is not a potential difference, but an electrical potential difference.
