If it'll make you feel better I had b44's '90's song "get down" stuck in my head. So whenever I encountered a problem I just imagined the physics paper getting 'down on me'... can't get worse than that. DO NOT LISTEN to '90's music before an exam, please DOONNNT!!

I keep forgetting that everyone on this forum is a state ranker lol. I felt like that this exam was really difficult, a lot harder than anything in the excel books and previous years... like wtf even was multiple choice I think I got like 10/20 for it lmao. But I think I did okay on everything else except the second last question

Also don't worry. looking at the general consensus, everyone was baffled by the paper. You've got this!

Haha that does make me feel a little better thanks. Also thanks for the warning, I’ll be sure to avoid any 90’s music before any uni exams

What do you think band 6 cut off will be?

What do you think band 6 cut off will be?

Id say high seventies to very low eighties, most likely high seventies in my opinion though.

okay that gives me some hope, hopefully I managed to scrape a high band 5 with my aligned mark.

 

[psmao]

Yep. Got tan theta = v^2/rg

lol i got

 

[Balajanovski]

lol i got

How?

Btw, what did everyone write for the experiments question? Just curious to see what people picked.

I wrote about Thomson's cathode ray experiment -> Shows that electrons are subatomic and fundamental.

I also wrote about the SLAC (Stanford Linear Accelerator) in 1969 which verified the existence of quarks. Showed that Murray Gellmann's hypothesis on quarks is not simply a useful way to break matter particles down into constituents, yet that quarks are actually real, physical, fundamental particles.

I said for electrons: Davisson germer, Millikan, Thomson. and for Higgs Boson: 2012 CERN synchrotron

Ahhh back in the linear accelerator days. simpler times

Good choices. How in depth did you go for the electron experiments? I went very in depth when I wrote about Thomson, doing all of the equation derivations and talking through the consequences of each step.

I put Davisson Germer showed electrons had wave-like properties. I also put the photoelectric effect experiment showing light had particle-like properties and that photons exist,

I went super in depth for all of them that I ended up writing twice as many lines as provided. I regret it though because I wasted too much time. I even talked about the details of the CRT and the process he used for the derivation. I wasted so much time - do not do what I did.

Hey that's a clever choice. I didn't see that you could tie in the Nature of Light module by talking about photons (which are a part of the Standard Model).

That’s a good choice - photons.

@Qiaochu Chen this is how I did it.
By resolving forces, we see that the centripetal force points inwards, and the bead experiences a downward acceleration.









Correct me if I'm wrong though.

HAHAHAH, I got this.
However, I used it in the form of banked tracks cause I had no idea how to do it. LOL! Maybe a mark or two???
I did state the car was turning...if that matters

Imagine someone mentioned gravitons lol

That moment when you see into the future and see a ground breaking experiment... during your HSC physics.

That moment when Higgs wrote about the Higgs Boson for his university thesis but got spanked by his university and then 50 years later...
