Omg TT btw, i absolutely love the hell out of u man!!! ur cheat sheet was soo amazing lol, i used urs+itute's+jack's notes to make this super special awesome one at 5am this morning hahaha talk about slack

how much does the exam score matter? dont they change your sac marks and exam scores so that everything is ranked according to your class within your school within the rest of victoria? thats what our teachers say anyway.
a kid doing chem last year did really well within his class. top exams & sacs but still only got a raw of 34 because nobody else in his class got above a d?

Its the other way around, if you ace exams, sacs dont really mean much

im pretty sure he got high as or low a+ on both the exams. that doesnt really warrent a 34 does it?

lol I think the iron bar occupies pretty much the whole space inside the wires, so it'd be hard to draw the lines not going through it

No I think you are misinterpreting what I'm saying. I had my field lines starting at the north end and looping around going to the south pole. I didn't draw them going through the iron core.

i drew four lines just outside the wire..i was tempted to draw inside it but refused...is that still correct?

i reckon this exam was too easy, i finished 1hour and 20minutes early.

for a second i was like WTF?! but then i realised that you only did detailed study. hahaha

[THem]

what would you need to get high 30 raw?

I'd like to know this as well

for the iron core Q i drew the lines inside the iron would i get full marks???

I don't know, I remember /0 saying every magnetic field must be a closed loop so I drew them through the iron.

Mathematically, you can express that statement as (field lines form closed loops).

However, not all field lines must form a closed loop, as the above statement is more of a simplifying definition (at least, as far as I know) rather then the grand truth.  Read: magnetic monopoles.

Well yeah that's true, but nobody's ever seen a magnetic monopole before!

crap i think i wrote 8.8 x 10^3 eV but i had 8870 or something in my working out
would that be one mark off...
