Itute solutions are upp!!
I'll get the ball rolling...
Damn for Question 2 electric power did we have to draw the magnetic field lines that wernt coming from the magnet?? coz i didnt :(
-
You forgot a link to the solutions ;)

Looking at that, I don't think I did as bad as I thought I did. Still made some really stupid mistakes, though :roll:
And, I think I screwed up Question 2 as well :x
-
Man, I'm stupid, I completely overlooked qn 1 saying draw 5 lines... and I drew prob like 6-8? Daaaamnn was hoping to scrape an A+ too, don't think so now though.
Anyone reckon I'll still get some form of marks for that?
I screwed qn 2 as well :(

electric power qn13..i heard that it might flicker...i wrote what itute did though...
"The globe will be off. The 12V battery supplies a constant
voltage to the input of the transformer. This results in a constant
magnetic field in the transformer core, which in turns results in a
constant magnetic flux in the secondary coil of the transformer."
overall i think i did waay better than chem...prolly lost 5marks according to itute...compared to the 8+ marks lost on chem
-
i did really well, dropped a max of about 5 marks
-
lol i thought the same about the spesh exam last yr, and i ended up actually dropping 10 marks. ==

I thought you didn't need the flicker part, just didn't sound like the concept they were trying to test here. 8)
-
yeah you didnt need to say anything about pulsing DC creating a changing flux... only that batteries are DC, so no change in flux, so no induced current, so no power to globe.
-
phew no mark lost then!
hooray for physics

the hydrogen/sun question was a joke.
the study design does not state a requirement to know the composition of the atmosphere of the earth.
i got the answer, but not doing chemistry (assuming that's the subject where you would learn this stuff) i thought it was a tad unfair.
-
I just said 'the sun has mainly hydrogen in it' (probably in better words) and that was all I really mentioned about the sun. Shows my deep understanding of it xD

I wrote "It got absorbed" as a very last-minute thing (right as they said "Pens down", whilst I was flicking through my exam to see if I had any incomplete answers). And seems like that's actually partially right... I wonder if they'll give me one mark for that? :D
-
Well absorbed is probably a keyword. So you might just get a mark. ^^

I disagree....how do you think they figured out that the sun had hydrogen in it?
we see the hydrogen emission spectra as having 2 spots that fit right in with the gaps in the suns absorption spectra...t his TELLS you that the sun/atmosphere has hydrogen in it.

Indeed, and they made it so obvious as well.
"Here is a zoomed up version that has lines in the same spot as the spectra we're about to ask you about..."
Might as well have wrote it in massive letters across the page.

yeah more i think about it the more it makes sense. i guess i was just lucky to guess it on the exam.
