personally i remembered more about volta than the others so i mentioned him. i was willing to write anything that i could remember on the subject.:D

yeah, i did the same as the smurf, but i also talked about how you can calculate the period and radius of a binary system. i only added that at the end 'cause i didn't think i had enough info for 4 marks....

i concur:D

UM, IF THAT WERE TRUE, THEN WOULDN'T THE 400 LINE BE ABOVE THE OTHER?. (whoops, caps on) yield is different to rate of reaction.....i was told that hi temp decreased yield....

yep, 14/15, me happy clam:D but err, why isn't 14 B? thats what i put. All the big mark questions were the exact ones that i studied for, ie SO2 and NOx one, shipwrecks one, water treatment etc. what was i so worried 'bout? happy clam:D hmmmm, me thinks the scaling on chem and phy will go...

anerobic bacteria don't need oxygen. they survive off sulphate. they reduce the sulphate ions and they react with water molecules to form sulphuric acid H2SO4. and oxygen gas. because they accumulate around ships. the water around the ships becomes slightly acid and aids corrosion. (i think.)

please don't leave sourie... we're all having so much fun ripping the shit outa yer. it's seriously easy!. so fucken easy. i finished rippin' yer off in half my normal time. it's so fucken easy!. (now where have i heard that before?). plz don't leave monkey boy. :D

if it makes you feel better about missing that 2 marks on nuclear reactions, i just realised i prbably lost 2 marks on the 7 marker.. i forgot to define resolution and sensativity! there goes two marks right away, damn. ps, i thought photometry was just used for measuring luminosity. i didn't...

nup, nup nup. think of it like this. it is harder to reach a speed of c, because as u speed up, time slows down. if it were the other way round there wouldn't be all those theories on tome travel. i.e if u can travel faster than c, the entrapy of time would reverse itself, and u could time...

ahhh. revelation... i seem to find them alot in chem. cheers!

hmm. i got 69 raw in trial. my mate got 7. and it was suppose to be a pretty easy test..... i've learnt a bit since then, but not that much... do any of you guys believe in life after death?

help me, i think i'm screwed...... everytime i do a heat of something calculation i fuck it up. why does it change from neutralization to heat of combustion. in the second half of the equation you have to divide by molar mass of some shit and in the other you mulitiply by some number you pluck...

hmmmm. sticks it to BlackJack!:D bloody good point. eddy currents couldn't be introduced unless the magnets are to strong and they penetrated the superconductor. in which case it would cease to superconduct anyway.....

hmmm i think you're probably right about s. its more in the region of brown dwarfs than white.....what did you put for that 7 marker, "and at least one other development." did you just talk about interferometry, or did you talk about something else as well. i didn't think of it in the exam, but...

i'm with big boy bob.. we were told its all scaled in the options...

never thought of that...... anyway it was probably the worst worded question in the test. and they didn't give us enough room to answer it. (i let them know this next to the question.) there was as much weighting and space for the q on the pendulum prac where we had to explain whose method was...

i think i felt that way about the test because i did more study for it than i ever done for anything in my life, then it turned out to be a pretty easy test. pissed me off a bit. i've got chem tommorrow and don't know much cause i spent all my time on physics. but after the physics test i don't...

no, it takes huge amounts of power to supercool the conductor to make it superconducting. the maglev train in japan runs on liquid nitrogen and is actual less energy efficient than a normal one. plus you have to power the magnets in the sides of the track to alternativly attract and repel the...

not me:D i'm not changin' i stand by 15/15 for MC. as for the rest.....criteria marking, shit. by the way, that pendulum one. i know you were suppose to find g from the gradient but couldn't. do you think i'll loose marks just using the formula?......:confused:

another way to think of the rollercoaster one is the centripedal acceleration/force, and how it relates to velocity and g at any given instant. centrapedal force is almost the same at p,q and r. (actually it's slightly less at p and r because the curve is parabolic). thus the descriminating...
