yeah, i reckon your gauranteed a question (out of 4) on one of the triumvirates, in some form. even if not, there will be a question that relates to it, like about the rise to power of one of the members

im a low 70's.. but i hav studied at least 5 times more for the hsc then trials etc

Answered everything, and should get some marks for it. But i know i won't get full marks in the big mark questions.

a couple of people left early in our exam, i think the earliest was about 1hr 10 mins. But i think that is so stupid. Even if you didn't study i reckon the least you could do for your hsc is sit it out and make up answers if you have to.

but with that? isn't that only from einsteins theory? I thought it hadn't been definately proved yet

i thought it was a pretty good exam, though maybe 3 questions were stretching what the syllabus asked.. I can't remember getting a lot of a's, mione were pretty spaced out (i think, didn't really look)

you guys have fun. still have ancient tmrw and ext. history on friday. It just won't stop.

i thought it was the cooktop, D.

It was the worst question. They didnt ask enough of you for how ever many marks it was Sppoke to my teacher afterwards and he thought is was stupid.

yeah, the only problem was the particle accelerator question. I reckon for a lot of the test they weren't given out marks right. Like there was a 6 mark question with only about 1/3 of a page to write, then later a 4 mark with a whole page..

i don't know of anything i got wrong yet, but i almost got the satellite periods one wrong because i had forgotten to square the period. Couldn't work out why the moons mass was greater than earths :D

the test was alright. Some really bad questions in it though. Like that michael jordan one definately shouldnt have been there, it was just crap. But i'm thinking about 75%

what about photocells?

yes the answer is D

i still have physics, ancient and ext history on wed, thrus, fri Getting so fed up with studying all the time, but feeling pretty good for physics. I know eveything when i go over it its just remembering it

are you all sure we need to know all these different ac motors? I swear the most the syllabus asks for is to contrast dc and ac.

davisson and germer proved the wave-particle duality of electrons by shooting them at a nickel crystal and notiving the constructive and destructive interference, which resulting in maxima and minima. The Braggs shot x-rays at a crystal specimen and knowing the wavelengths and such analysed...

so the balmer series just shows the energy (wavelengths of light) emitted when an electron jumps from a high energy level to a lower energy level? And that came form bohrs postulates which explain the stability of the atom, and energy released

it depends on the amount of marks the quesion is worth. Start with quarks and leptons then move from there depending on how many marks (and hence lines) is needed

can someone please explain the balmers series stuff to me
