I share those sentiments

That was surprisingly easy. If you knew your theory, you would've aced it. No real challenging questions if you compare them to exams in previous years.

SUUUUUUUUDDDDIIIIISSHHHHH!!!!!!

hey i was wondering...my friend said that you need to full mark both physics exams to get a 50. is this true? o.O

This is not true, last year 16 people got 50s and only 6 people got 100% on the unit 3 and that was an easier exam

For the brightness graph, if you drew a curvy instead of straight wave, but everything else was right (it was inverted and above 0) will you still get 1 mark out of the two?

Maybe even 2/2, it was technically curvy (if you perform the calcs from P=VI you see that you get a curvy graph with cusps). But VCAA will pay both (if your curvy one was cusped).

It would only be very, very mildly curvy though I think.

Yeah, even in 2009 I doubt you needed full marks on both exams to get 50. I got 50 with rank 1, but didn't get a premiers, so I'm presuming that you could drop a mark on the second exam to get a 50, despite the uber high marks scored that year.

The structures and material question about the cylinder, what stress was it under? Definitely not plastic or elastic which leaves shear or tension? I was inclined to put shear but convinced myself it was tension at the time because it replicated a pulley system which is under tension from the rope. The dux of physics last year at my school also agreed.

26 minutes to go finished materials and motion only electronics left. First question begin reading... 20 minutes later falling to pieces because i can't do. Skip do some questions quickly the rest cannot do because it messed with my head. I hate that question so much. Unit 4 exam prep begins now.

sigh...did the stupidest mistake. Placed Vout over the thermistor T-T

Funny thing is, that I changed my diagram (got it right) and forgot to change my calculations for R accordingly. Lucky to get one mark for that, if any...

FAIL.

I said tension but it has been generally accepted that the answer was shear, so yeah. :/

It was sooooo long...enough said
