Physics Predictions/Thoughts (2 Viewers)

[scaryshark09]

what if there are only 2 people in a physics class (this is just a thought experiment)
person A is ranked first
person B is ranked second

in the hsc exams, person A absolutely bombs the exam and gets like 20%
person B gets 80%

won't person B's hsc mark be made up of his exam mark (80%) and the exam mark of 2nd place (20%)? that doesnt seem fair

rank 1 gets the highest exam mark as their internal, and rank last gets the lowest exam mark as their internal (WHERE POSSIBLE)

in this case, carrots is right and person A would be considered an outlier. person B would definitely not get 20 as their internal, unless their raw percentage gap was massive for their assessments

wtf the carrots and chilli pfp look the same its hurting my eyes

@carrotsss what would happen if the person ranked second got like 94 and the person who was first got 80, but there was only like a 2 mark gap between internal marks, and assuming the rest of the class performs similarly in the exam as their internals, do you know what would happen to the moderated assessment mark of the person ranked second? would it be 80?

if there was only a 2 mark gap, rank 2nd would definitely not get a moderated assessment mark of 80, considering rank 1st would get a moderated assessment mark of 94.
the exact number would depend slightly on how everyone else performs, but it would be around 90-92 moderated assessment mark for rank 2nd, as they take into account the raw percentage gap between ranks.

SHUT UP NERDS GO LEARN HOW TO TOUCH GRAS! PERIOD YUHH YASS QIEEN

Who needs to touch grass more? The nerds on a nerd forum? Or the nerd in denial telling nerds on a nerd forum that they need to touch grass.

nesa put the paper up:

For question 34b, why do they give us the potential energy? I just subtracted total by potential. How much marks do you think they will give me?

Retarded trick question

I did the same, I’m sayin 2

Hey guys. Does anyone have the solution to the last question of 2023 HSC physics? Thanks

I put one in post #444

 

[tywebb]

And here is another solution. This one also includes solutions to the q33 and 34

 

[tywebb]

It's a bit hard to read isn't it. So here is a latexed version of the q33 and 34 from this one.

 

[tywebb]

so now joining it to eddie's we have a latexed version for the whole paper

 

[tywebb]

I reproduced in latex the calculations for q34 faithfully to the handwritten one - regardless of mistakes and/or skipped steps.

I checked them with a calculator with values of G and M_E as presented in the HSC exam data sheet and they seem to be correct.

But do you think it could be improved with more steps showing substitution of values?

Happy to do that later if you think it necessary.

Also if you use more accurate values of G and M_E you actually get different answers.

and now this mg from nesa: https://educationstandards.nsw.edu....-f8f0c52a-4329-4b8b-b330-4a9ea336d452-oLRjsR6
