One of the questions I must answer for my upcoming assessment (concerning the photoelectric effect and the particle model of light) asks: Regarding light, what are some possible future directions of Physics research? Here's what I have so far: Classically, light was considered to be a wave by...

This is the question: http://imgur.com/9t4UWJO My solution(s): http://imgur.com/p28GCzW Me and my teacher both had similar approaches to parts i and ii, however, we had different approaches to part iii. I am probably more inclined to trust his method (Method 2 on my solution sheet) as...

My prescribed text is Go Back to Where You Came From, which if you are unaware, is a TV show in which regular Australian people 'discover' the tough life of refugees and asylum seekers. I need a related text though. I have found "Neighbours", by Tim Winton, which is concerned with a very...

Ok, I've been reading a lot about the Meissner effect and have looked at old threads on this forum which ask similar questions to mine, but haven't been able to find a good answer. In the situation where a magnet is placed on a warm superconductor, which is then cooled, and the magnet will start...

Physics: 1/10 (Avg 97%) Chemistry: 1/10 (Avg 98%) Maths Ext 1: 1/8 (Avg 98%) Maths Ext 2: 1/2 (Avg 99%) English Advanced: around 3-6/~30 (I don't know my exact rank, this is simply an estimate) (Avg 90%) I should say that the first English assessment was weighted 25%, and pretty much all of...

http://imgur.com/fGMFrEa My teachers say that this question is flawed: is it?

http://imgur.com/jghkxRx For some reason, I'm stuck on part ii: I know that beta is equal to p^3 + p^5 + p^6, but I cannot find a way to "justify your answer". It's probably really obvious but I just can't see it. By the way, I'm fine with all other parts of the question.

Ok, so I'm a little confused about this. 9.3.5i says "describe the main features of an AC electric motor" My teacher says that he suspects that this refers to an induction motor, however both textbooks that I have (Physics in Focus and Excel HSC Physics) state that an "AC motor" is just...

Hi guys, If an exam asked for a diagram of an AC motor, would this diagram be good enough: https://imgur.com/CHd9unr Is that good enough, or should I draw it from a different angle? Is there anything that I forgot to include? Thanks.

https://imgur.com/sZ3AfXj I was curious as to whether some kind of numerical calculation would be required, seeing as they provide heaps of numbers. The thing is, I wouldn't know how to calculate anything using what they've given. Help, anyone?

For part iii, is it enough to do the following proof? I spent ages trying to look for a way to prove that opposite angles are supplementary (this is usually what questions like this want), but couldn't figure it out.

https://imgur.com/rVbvxpi My teacher says that for haloalkanes, we should number the carbons so that the first alphabetical halogen (in this case, bromine) has priority, rather than numbering them in a way so that the all of the halogens have equal priority in the numbering process. However...

My physics teacher gave our class a past paper which included a question concerning simultaneity. He said that the question was actually wrong: https://imgur.com/6dtHN7w He said that to M, the strikes would NOT be simultaneous, but that M would see the strike from Q before the one from P. I...
