physics

A question popped up in a physics textbook and I would just like to clarify my answer: a) My answer: Potential difference is positive so ΔV = ΔU/q and since potential difference is positive so must be ΔU. ΔU = q*ΔV = (-1.602 * 10^-19)(100) = -1.602 * 10^-17 ΔU = -ΔKe -1.602 * 10^-17 =...

Can anyone recommend experienced online physics tutors? I live pretty far away from the city and wouldn't be able to do in-person classes, however can come down to Sydney if classes are held on weekends. I need a tutor that's able to teach just as well online as they can offline, and keeps...

Hi, I have a practical process task for mod 6 for both chemistry and physics so what are possible things they may ask us to do. Additionally, how would you guys recommend I study for these sort of tasks, and what is the best approach to maximise marks? Also if anyone has any past papers of...

Hi, I picked my subjects for prelims '23 recently: - SOR 2 (compulsory to have 12 units exact even tho I average Bs in religion) - Physics - Eco - Math Ext & Adv - Eng Ext & Adv I wanted to switch eco for smth else because it might be too much on top of everything else. If I do, I'll change to...

What is the difference between uncertainty and accuracy? I've been reading through some NESA documents and they seem to use the two words interchangeably. Is there a difference? Thanks :)

Anyone know how to study for year 12 phys in terms of learning the content? I was going to just read over the textbook and take notes along the way but I was wondering if anyone had any better strategies?

Can someone explain why the answer is A. I thought the speed decreases and hence frequency increases c=fλ (B).

Answers say C I think it has to be A. Someone pls come to the rescue with the correct explanation.

Can anybody help rank these tutoring centres based on personal experience or word of mouth??? (Reasoning or partial rankings would also be greatly appreciated!!)

You don't need to worry about your subjects being helpful in your future degree/course (unless it is a prerequisite) - but considering the information you've provided it seems that you are more interested in physics so perhaps you should consider dropping software in that case

So Im currently in year 10 choosing my subjects for year 11 and 12. As the title suggests, im a bit conflicted with choosing between either bio or physics. Ive already decided on math advanced, math extension 1, english advanced, economics, business studies and chemistry. Most of these are...

Hi, In preparation for the prelim exams, I am on the search for past papers, however, almost all of the papers I have found are from the old syllabus (pre-2018) and I am not sure where I can find new syllabus papers. So if anyone has past papers/knows a website I can view past papers for...

I am a bit confused about the mass defect occurring from nuclear fission/fusion reactions. Online sources + textbooks say that the products of a nuclear fusion reaction will have less mass than the reactants, and will release energy in relation to E=mc^2. But in my matrix book, they are saying...

Hi all, I am thinking about starting a mistakes book to get into a good habit of writing down all my mistakes. However, I have never done this before so any advice would be great. Thank you

Hi, I have a physics practical process task for mod 3: waves and thermo coming up in one week, and I am seeking general advice and any predictions on what could be asked. Thanks, Dhwanit

I have to do a year 11 depth study into waves and its due at the end of the term but we've only just started doing waves, has anyone got any ideas because I am hopelessly lost

Hi, I'm wondering if anyone here has done the Macquarie Uni study lab for physics and/or chemistry and if it is worth buying. (it did not let me post the URL) Thanks, Dhwanit

Hi so I was given this assessment task like a week ago, its due next week and I have no clue where to start. I, unfortunately, ended up with a teacher who isn't that great at actually teaching the content and he hasn't explained the assessment task well, so basically, everyone in my class is...

Hi Everyone! I am a part of a group of 2021 HSC graduates who collectively achieved ATARs ranging from 96 - 99.85, excelling in a variety of subjects including; Extension 1-2 Maths, Advanced English, Chemistry and Physics. Being from different schools, we decided to compile a Google Drive...
