A low earth orbit is an orbit within the range of 300km to 1000km above the earth's surface. The period of objects in this orbital range are around 1 hour. Low earth orbit satellites experience high air resistance, and, must be boosted often in order to maintain their circular orbit and avoid...

next question. Explain in depth how power transmission lines are protected from lightning strikes and are insulated from electrical arcing.

I will give it a crack, superconductivity is the one area I need to revise the most, but here we go. The BCS theory suggests that when a superconductive material is cooled below its critical temperature, the electrons experience no resistance within the positive lattice of the material. The...

good suggestion, I see what u mean.

not really possible seeing as it is so fleetingly touched on in the syllabus haha

At the positive terminal, electrons are being taken from the solution and into the external circuit. As electrons are being taken from solution, we know that an oxidation is occurring. And hence it is labelled the anode as oxidation occurs at the anode.

find the cartesian equation of the motion of the particle. And then find the intersection of this equation and the line y=tan(b)x by using simultaneous equations

Einstein suggested that in reality, at the speed of light, c, his reflection would still be observable, yet also the light would still be travelling at c relative to him. As Einstein believed that the laws of special relativity could not be violated in any situation, the speed of light must...

i hope you are referring to mila kunis rather than me ;) next thurs i got a mozza of time :) From here on in I am only studying for english and physics.

my daddy just started hitting me. he said it's because of the carbon tax. can't blame him

"1. They don't rape us with random questions" guaranteed to happen at least once. Is the next one tomorrow?

hahaha wtf, you finish your first english paper and make like 10000 new posts. howd it go?

82~ why didn't you hand in your assignment? and yep it will have a dramatic effect on your rank, probably resulting in it being the subject that doesn't count.

well the add for weight watchers on this thread currently has a $0 joining fee, so it must be!

ahahahah

how many marks for a correct response?

I have annotated how well these scale in the quote. this is just off the top of my head but fairly close. have a look here to see exactly how it was last year. http://www.uac.edu.au/documents/atar/2011_HSC_Table%20A3.pdf

yeh well it's a hard job with people always expecting u to do spells and talk to god and all that jazz

you can't tell because it is a percentile dude.
