Re: OFFICIAL PHYSICS HSC 2015 Prophecies!!!!! --> FROM A NOSTRADAMUS DESCENDANT!!!!!! There's a lot on the line you see ;) Alhamdulillah, cheers bro

Wow, would think someone would get 50+...

Re: OFFICIAL PHYSICS HSC 2015 Prophecies!!!!! --> FROM A NOSTRADAMUS DESCENDANT!!!!!! Gonna commit suicide if that happens. I will make it. Nws

Re: OFFICIAL PHYSICS HSC 2015 Prophecies!!!!! --> FROM A NOSTRADAMUS DESCENDANT!!!!!! What's the vision on my physics mark Masha Allah

re: HSC Physics Marathon Archive I'll list the main points: Society: - Widespread distribution of electricity through the production of AC -> talk about transformation + effectiveness of AC (powerloss etc.) -> maximising efficiency as less energy loss = lower cost etc - The electricity...

re: HSC Physics Marathon Archive What is the official HSC explanation as to why magnets 'levitate' above a superconductor (cooled blow T_c)

re: HSC Physics Marathon Archive Hertz is the emasure of frequency Since E=hf, you can calc it that way

re: HSC Physics Marathon Archive A little bit of refining, as Kap mentioned. Also, holding the string is not valid, you should hang it on the roof (if you're in a car etc.)

re: HSC Physics Marathon Archive Describe an investigation to help distinguish between non-inertial and inertial frames of reference (3)

re: HSC Physics Marathon Archive How do intrinsic semiconductors carry current? (3)

re: HSC Physics Marathon Archive Technically, it induces an emf, which gives rise to a current

re: HSC Physics Marathon Archive Heisenberg: – Heisenberg founded matrix mechanics, a mathematical system which provided an explanation for the nature of small particles (e.g. electrons and protons) and their interactions. Matrix mechanics was able to successfully predict and mathematically...

re: HSC Physics Marathon Archive BAHAHAHAHAAHA, yup, it's fun doe

re: HSC Physics Marathon Archive hehehe, it depends on how well you know about the donor/acceptor (Fermi) levels in the energy band theory -> and what this actually implies

re: HSC Physics Marathon Archive Bump If anyone can get the full 8 marks, I'll shout cookies

re: HSC Physics Marathon Archive F(c)=mv^2/r v=2pir/T

re: HSC Physics Marathon Archive What are the advantages of DC transmission over AC transmission (5 marks)

re: HSC Physics Marathon Archive How does doping affect the way a current is carried in a semiconductor? (5)

Wrote it for safety. How is 4 marks awarded to a graph. Like wtf, srs

Probably, Shipwrecks this year was really easy :/ Rekt by that Q doe, nothing else seemed to stump anyone
