i doubt copper is a super conductor... i wrote something like... due to the reduced vibration in the lattice under such low temperature, the resistance will be low... hence it's easier for current to flow n the eddy current will b greater and this will slow the magnet even more...
i thought there were heaps of trick questions in the multiple choice... =_=
i found it the harder than the past papers... there was nothing like equating centripetal force and magnetic force that kinda stuff which i love..... e.g. the bubble chamber question from 05 was fun... >.< sigh... i...

15. B (sigh... 25% chance... n i guessed it wrong...)
use the line of best fit to work out the gradient... n then u can find the distance through that...
since equation of a straight line is y=mx+b
u just rearrange the force between two conductors formula... and u'll get something like this:
F = kI(upper)I(lower)L/d
and since I(lower) is the...
i had no idea what it was called... but the idea about only few houses had kitchens just popped into my mind and i went on about how the lower classes would have often eat outside due to the lack of kitchens in homes. =P
i just never expected a question on food... >.< i've only learnt so...
i typed my notes n then print them off...
society: 22 pages
historical period: 12 pages
personality: 10 pages
core: 30... core study was hell... =_= teacher gave us all these notes since it's the first year for the new hsc with the core studies included and she has no idea how much we have...
yea... i feel the same as fearless86...
you need to link them together... and also i think it will help to use topic sentences, so that it is evident that you've referred to the question and actually answering it.
>.< my class is waaaaaaaaaay behind...
we r half way through elective: medical physics and only 2 chapters through space... lucky i have a tutor....... =_=
just did my trial on monday =]
>< i think i stuffed it up... but i reckon this is an average 3U paper... though i left the whole question 7 and part b) ii> and iii> of question 6 out... hmmm... i am not aiming for an E4 coz i know it's not likely for me... but what raw mark do u need for an E3 band??
