I'm not sure the ring experiment is required. What's more important is to go into a bit of detail about the magnet and air-cored solenoid coil Faraday used (as far as we're concerned). I.e an analysis of the effect of speed, magnet direction, strength (similar to the prac), as well as some sort...

I'm not sure Lenz's law is at all useful in this case. That simply describes the force on the conductor which naturally opposes the original direction of motion. What we're interested in is the charge separation of the conductor. I'm not sure about this, but I always thought that the negative...

That's Keypad right?

wow...poiuytrewqwerty has some pretty big problems.

essay:11 creative:6.5 about 12 or 13 words/line

yeh, the essay for revenge (and probs other genres as well) was slightly weird - concentrating on consumption of revenger and those around them, as well as addressing concerns and conventions of the genre...structuring the essay was slightly weird. I did the whole law is unattainable...

Yep, it was about the consumption of the revenger - how he becomes corrupted morally i took it as, though you could talk about the death of the revenger as well

I'm fairly sure I lost 1 mark in the whole thing. Apart from that 1 mark, I'm not sure if I lost any others - I checked it and fixed up the silly errors, and my answers seem to correlate to the accepted answers for all the questions, but then again anything can happen in these things, as...

having 40 mins left is indeed physically possible...it's all about racing through q's 1-5, and leaving enough time to correct the inevitable mistakes :) So, basically a go through in 1hr 20, then 40 mins of close checking for errors you know occurred... Some moral support would be...

Hehe, the guy on the tape teaches at our school, and yes he does have a tendency to speak fast at times in listenings.

more like 0.5 is nowhere near 0.71 :)

expecting ~105 for 4u :( , 83 for 3u :)

As last questions go in extension 1, I'm pretty sure that today's was as easy as it gets, especially easier than last year's one where they simply threw you into the deep end...

Rorix, how did you go? 84?

Time was 4:28 am Me, I'm hoping for 83/84...didn't include the second solution to the tantheta question in 6...I hope i get a mark for that. Apart from that, I'm fairly confident of not having committed any sillies...

hehe 4hours sleep? poor rorix...i had an hour and a half's sleep before my 4u trial. Again, couldn't sleep....

there is only one mole of Cu2+ ions for every mole of copper sulfate. 0.03/0.0295M (i don't think they'll be too picky with sig figs tho I hope they r :) ) is right.

you should have realised the lack of real chem in the syllabus before now surely...

yep, real gimme. Wrote on abt 10-15 more lines, plus a graph :)
