i wound up writing 2 summaries for my courses - the one i did along the way, which wound up containing stuff that i didnt need to study (either because it was really basic, or i knew it really well), and the summary i wrote up last week, which has the stuff i consistently get wrong or need to...

What have they actually cut out for next year?

Somebody write out all the possibilities... Tell us which way is right. But dont miscount :)

oxygen's overrated anyway. im too cool for it. think of how big the paper planes could get if u made them out of 3 trees each... thats a noble cause - id give my share of oxygen up to realise that dream :)

i think everyone should celebrate - its the last time you have to see most of the people from school. thats a good thing :) and im sure that *COUGHskanksatskoolcough* are really nice people - u just met them under adverse circumstances. ;) actually the people from my year scared me we had...

there is something fiendish about maths everytime i think ive got something down pat, someone demonstrates that i dont. its not fair :( i should be able to be consistently competent. i havent even seen that type of question dealt with like that. if i ignore it will it go away?

trees --> HSC paper HSC --> flunked trees --> wasted its a horrible cycle

pfft my school's name is already dirt i couldnt possibly make it worse. and thats my problem... the formal is serious. i dont know, something inside me really chafes at the idea. but i dont think anyone is going to miss my absence from the formal and i never had money for cabs in yr 10...

at least something important is expended on our education :giddy:

woops meant hydrogen

Well no i dont think they could just ban me from the formal - i didnt hurt anybody. but some of the year are taking the formal deadly serious now, and i prolly would have upset someone if i did anything like that :D and its really hard to dance when you put the head on - u can hardly see...

Eh.. yes thats right. But to get your exam back, you would need to break into the marking center, sort through however many thousands there are, and sneak back out... after they record your marks, but before they recycle the paper (just imagine how many half decent stories get destroyed every...

Hehe i was asked very politely not to come to yr 12 formal if i was not going to take it seriously...(didnt want to anyway) yr 10 formal, i was dared to go in a giant pink bunny suit. so i did. i thought it was pretty funny. principle never talked to me again :)

that doesnt help me. i would like to know how they do it. i dont (and never really have) but i get the feeling that im supposed to...

this way they appear infallible :mad1:

so whats the mass of deuterium (compared to helium's 1.00778 u)? its 2.01645 u isnt it? because thats what i got, but the answer provided is lieing to me :mad1:

i dont follow. im pretty confident i did it the right way. way to knock my confidence out from under me :p

thats how i figured it. 8p3/2!

I thought someone already answered this Power remains the same (initial vI=final vI), its just if voltage in second coil goes up, current goes down - therefore no new energy. is that what you meant?

Ok i am really shaky on this... I know the defect becomes the binding energy, but how do you actually determine the mass defect in a nuclear equation? eg 2H + 2H --> 4He 1___1____ 2 I have an answer but i cant see how to get it :(
