Exam Discussion!

[silverpixeli]

Just finished my brother's brand new personalised 5-hours-of-work cheat sheet, while he's getting a good night's sleep.

There aren't many hours left till the start of the physics exam, good luck everyone!

Feel free to use this thread for discussion after the exam, too. Once I see a paper I'll be happy to discuss with you all.

Edit: itute made some answers! thanks for the original post

Edit 2: Physics teacher got me a copy of the paper, there's now a scan available HERE (5.17MB)

 Good on you man, not many people would do that for someone else.

Spring question?

[Marrogi12]

Any answers ?

[liamh96]

That was rather tricky. Definitely harder than last years. I've noticed that VCAA have been starting to employ more extended-response type questions which I found kind of annoying. Hopefully the A+ cutoff is quite a bit lower than last years

[speedy]

Definitely a tough exam -> finished with a couple minutes to go lol (I'm slow though).

[Plitzer]

I found this years exam quite standard. There was quite a lot of extended response type questions though so that probably threw a lot of people off. In terms of the difficulty of the questions there were a couple that were slightly more difficult, but overall it wasn't that hard.

That modulation question though... what did your graphs look like?

[shroomer101]

that modulation question with the carrier wave threw me off haha but yeah i found it a bit harder than last year paper

Spring question?

I believe it was:
1. 0.8 m
2. Didn't take kinetic energy into account. Ek+Ep+Es=constant.
3. 2 ms-1

[rui97]

I believe it was:
1. 0.8 m
2. Didn't take kinetic energy into account. Ek+Ep+Es=constant.
3. 2 ms-1

looking around, yeah that seems to be the general consensus

[shroomer101]

I believe it was:
1. 0.8 m
2. Didn't take kinetic energy into account. Ek+Ep+Es=constant.
3. 2 ms-1

yaay i think i got all of that too

for the modulation i drew them translated up and did something weird for it i dont even know myself...it was two marks from my memory

also for the light globe question with the maximum of 6V what did everyone get??

I got 26V, may not be right tho.

[rui97]

I got 26V, may not be right tho.

yep same

[Plitzer]

I got 26V, may not be right tho.

Yeah 26 V, the Voltage drop along the transmission lines was 20V and 6V had to be supplied to the globe, so a maximum supply of 26V was needed

For the modulation question I basically copied the carrier wave graph from 0 to 4.5ms but translated a little bit, then repeated the pattern at a lower point for after 5ms

[speedy]

I believe it was:
1. 0.8 m
2. Didn't take kinetic energy into account. Ek+Ep+Es=constant.
3. 2 ms-1

Hmm, I got 0.8 -> but then I said 0.4 for "extension", which I took as length that it has been extended from its initial length.
