DID YOU SEE THE CENTRIPETAL FORCE QUESTION THOUGH? How stupid was that?!! And of their projectile motion question was so wack and they provided the wrong answer, smh.

Yeah. I just hate the way CSSA did it though. It was so demoralising to see that question, I’ve never seen a physics question that hard (given you haven’t already learnt about neutrinos already). They could’ve provided a bit more detail on how neutrinos could were also ejected along with the...

Yeah I’d also tack on the ‘thus violating the law of conservation of energy’ for the UV catastrophe since NESA seems to LOVE that.

Na that should be fine. Also how in depth are you going with describing it for that? Because I don’t know whether to paint the full picture with the “light clocks” (that can’t exist) or just illustrate a basic framework. Also, with regards to blackbody radiation are you going into full detail...

It’s honestly so awful how as the new syllabus we’re left in such a grey area on what we should know and what’s out of the syllabus, and it’s worse when trial paper examiners try to flex their physics knowledge and increase their reputation by including unrelated pieces of trash questions that...

Ikr!! Especially with glucose polymer questions and the chalcopyrite mining

Oh sorry! I thought you said “didn’t validate SR” haha. My bad.

Excel also had a lot of question out of the syllabus; at least in my experience with chemistry, I’m not too sure about physics as I just generally rely on past papers and trials. Do you think they could assess simultaneity of relativity as a part of the new syllabus? Because it was favoured in...

I don’t think neutrinos are part of the syllabus, I learnt it however but pretty sure my tutor mentioned that neutrinos are one of those topics they could care less about, especially in equations

It did validate SR. Recall Einstein’s first postulate: the speed of light is constant in all frames of reference, now if the luminiferous ether were present that would indicate that there is a favoured reference frame; which simply cannot be true according to Einstein. But yeah, it is a vague...

Agreed. I think the most accurate paper so far has to be the PEM trial, although it is riddled with errors.

I’m going to be flat out honest with you, if I was a student who hadn’t known about the work of Pauli, there was NO WAY my mind would jump to the conclusion that there had to be the existence of another particle emitted from beta decay, it’s just too much for a high school student. Also...

Correct me if I’m wrong, did they also forget to mention the debunking or ‘erroneous’ existence of the luminiferous ether? Because I remember mentioning that but I don’t think I saw them mention it, unless I’m recalling incorrectly

This, this is utter nonsense to me. The whole point of the validation of a theory is to seek experimental evidence - I do not understand how ‘thought experiments’ would suffice, I would’ve mentioned the work of Hafele-Keating and atomic clocks as well as muons and maybe cosmic rays (I wouldn’t...

I was wondering the exact same thing about this when I did the independent trial papers. No, I do not believe we need to know the works of Poincare and Lorentz, however everything else in the marking guidelines is accurate; the requirements of specifying the constancy of the speed of light as...

Oh okay, thanks for the info. I too would like to know if you’d have to purchase your responses separately, but I’ll do some digging to find that out.

Hey guys, Okay, so I know that to receive your raw marks you’ll have to pay for a clerical check and what not and it costs ~$30 (except for English). However, my question is that I’ve heard people say even if they notice an error in counting that should bring your mark DOWN that they cannot do...

Just freshly graduated from chem, but still a bit cooked from the test aha, so I’ll answer it from the top of my head. the seeds are ground in order to increase surface area to increase the solubility. also remember the term dynamic equilibrium; this state is reached when the system is closed...

It’s likely a skills test involving data processing, so it doesn’t matter if its from the syllabus explicitly. All the details you need to know will be provided, it is just a matter of critical thinking to reason your way through it. This is coming from a 2019 HSC student who had the pendulum...

Sorry if it’s clunky, didn’t re read it. Also I might have misquoted some stuff
