Physics Examination Discussion

I thought north was up the page :s

Yeah it was haha my bad

I think I screwed up a question. I wrote that they measured the displacement wrong in the spring as it was written to be 1 or something, but it was supposed to be 1.5 (from 2m). However, I worked out the energy and it was 0.5(10)(1.5)^2 = 11.25.
What the frick, did I just mess that up or did vcaa?

[silverpixeli]

11.25 is right, that's the total energy and it's all SPE at the bottom of the motion

At the top, there's 10J of GPE and 1.25J of SPE (they stuffed up the extension there, too, it's not 0 SPE)

So it's actually 11.25 at both top and bottom, as it should be

What happens if you write in pencil?

[eddybaha]

you get 0

What happens if you write in pencil?

It gets scanned, so they might not be able to see it. Hope you didn't use a light pencil like a 2H.

What happens if you write in pencil?

If it was hard enough you should be fine. The only worry - and reason they tell you to use pen - is that in scanning the exams, lighter pencil might not show up so well and that would annoy examiners if they have to strain to try and work out what you've done.

To be honest, I thought the exam was pretty much on par with past VCAA exams, maybe a little bit easier overall but with a couple of harder-than-usual questions. Synchrotron detailed study was ridiculously simple, but I hear that a few of the detailed studies were a bit that way. I will never understand why they are two marks each. But yeah, I've never been that confident after a physics practice exam, so I guess that's promising

Ah.......... I think I'll lose a mark or two there.
This is not good, probably lost about 3 min.
Idk what the a+ cut off will be, hopefully it's like 132.

What happens if you write in pencil?

The very reason why they ask you to write in blue or black pen is so that they can see your writing clearly when they view your exam on a computer monitor. It's always best to follow the instructions that they give you, just for peace of mind. In the assessment reports for some subjects, they mention that their ability to read your work can vary a lot, depending on how you write and the type of pencil you use. Our teacher also warned us that assessors have been told not to go out of their way to try and understand what you've written either (this also applies to legibility of handwriting). The assessors will still endeavour to read your work, but if they can't, you will receive a zero. I hope for your sake that it all works out OK.

What happens if you write in pencil?

From what ive heard, if its too hard to read the assesor will get the actual exam paper or soething to that effect.

[Henreezy]

For sound is it 60 or 70 dB?

70

For the SECOND time in a physics exam (last year semester one physics as well)
my school had a power outage. It has not happened, to my knowledge, any other time in 2012-2013, just the two times I've had physics exams. As a result, my exam started at 10.25. You heard me. Everyone sat in the dark, silently (VCAA supervisor and the teachers didn't let us talk) for an hour. Sigh. That is literally the longest VCE exam people will have had. Four hours.

What are the odds?

[Stick]

Electricity, light and Physics... oh the irony.

In all seriousness, I didn't realise that that was the procedure during a power outage. I hope you still did well, nliu.

last year when the power went out at my school during the english exam, they transferred everyone to another area, i don't know how they exactly did it though.
