re: HSC Physics Marathon Archive as light provides the energy for electrons to be continually removed from the n-type. The current would not remain if there was no light. Initially the electric field would be set up as the electrons move in the holes but then nothing would happen

so glad i dropped after trials

re: HSC Physics Marathon Archive Does my response have the right idea though if i explained it better?? (sorry it was 11pm and i coudln't be fucked answering a whole 6 marker)

Re: OFFICIAL PHYSICS HSC 2015 Prophecies!!!!! --> FROM A NOSTRADAMUS DESCENDANT!!!!!! Looking forward to having more visions tonight. It will be my last chance to be correct.

re: HSC Physics Marathon Archive A solar cell is formed when two differently doped semiconductors are placed next to eachother. One of these semi-conductors must be doped with a group 3 element becoming a p-type semiconductor, and the other must be doped with a group 5 element becoming an...

Re: OFFICIAL PHYSICS HSC 2015 Prophecies!!!!! --> FROM A NOSTRADAMUS DESCENDANT!!!!!! Don't worry ---> Re-added you in. Just needed to make it more general in case another nostradamus relative "popped up"

Yeh. It was me and i didn't explicitly called WSU a pleb uni, it was just a comment about other uni's (as you can see from my comment above). Anyway it was just as a joke as well as i later said..lol. Anyway both UOW and WSU used to be crap but its really rapidly developing and is actually a...

Re: OFFICIAL PHYSICS HSC 2015 Prophecies!!!!! --> FROM A NOSTRADAMUS DESCENDANT!!!!!! It's true though. Even getting a band 6 is pretty hard --> but hopefully i can get it, just need to improve my Multiple Choice. Currently am only getting 13 (on my bad days) and usually around 15/20 (on...

Just know that electrons cannot have all 4 quantum numbers the same (for example one being spin --> but you don't need to know any of these quantum numbers). This explained the max number of electrons in each shell, and provided a quantum explanation for the position of the first 20 elements in...

Re: OFFICIAL PHYSICS HSC 2015 Prophecies!!!!! --> FROM A NOSTRADAMUS DESCENDANT!!!!!! You need a bit of luck to get 98+ examination mark as well. So hopefully the gods are on your side Kaido.

re: HSC Physics Marathon Archive Relativity of simulteneity: 2 events that are simultaneous in one frame of reference will NOT be simultaneous in any other inertial frame of reference. 2011 HSC Q24 is a question on this. My answer to that is: The method would work only from the perspective...

re: HSC Physics Marathon Archive Explain what a change in gravitational potential energy is and why it is a negative. 3 MARKS

If you yourself are travelling at relavistic speeds, time periods become LONGER, meaning 1 second to you is longer than 1 second to someone watching in a different frame of reference. So you could travel to mars say in 1 year (it feels like to you), but to someone on earth it was like 4...

its too far away for a lot of people. But yeh its growing pretty quickly
