CSSA Maths Ext 1 2011 it was easier than I thought but probably made careless mistakes.. anyways, Discuss!

lol the question about compare the lead and another battery?

if you have any questions regarding a certain concept or just any question on a dotpoint then I can give you some info on it and explain it to you

nah that's fine. as long as you gave examples for it's use, problems and how we reolve those problems then it should be all sweet.

oh aiight. yeah I just talked about protostar, then young star, red giant, planetary nebulae and white dwarf.. but it says 10 different mass of stars. I was like.. wtf?! 10 different explanation? haha and yeah just drew the H-R diagram. yup some mc were challenging but overall it was okay I...

how did you go with physics trials?

what's mech eng like?

yup talked about this too.. I dont think you need to mention the charge/mass ratio cause it contained a fluorescent screen.. so yeah hoping it's thermionic emission

How do I improve in maths ext 1? like i'm all sweet with 2 unit but when it comes to ext1, I just cant see the solution.

cutting down on the info. had the same problem before. you might think that every sentence is important, but once you read over it once or twice, the key concepts and info should stand out. and before you read, know what the question is or why you're reading the info. like have a dotpoint in...

What's scif? and please elaborate on that.

any suggestions for what uni course to do? subjects are in my signature.. can't decide right now so asking for help. Thanks!

lol part 1 of the question says calculate energy of a laser and wavelength was given. part 2 says the laser was shone on a metal which was connected to an ammeter. the intensity of the laser light was adjusted from zero to its maximum however a current was not detected. explain with reference to...

Re: Question on difficulty of CSSA physics discuss ac dc war with westing and edison and how ac provides eddy currets. production of eddy currents, it's uses and problems. Uses of superconductor and it's impact on society and environment and just short answers throughout.

it says that light is intensified but current was not detected. I talked about photoelectric effect for electron flow. then said the work function and threshold frequency of the metal. then energy and frequency is proportional in a photon. then photon transfers all or none of it energy...

how was it and your thoughts on it?

lol yup my bad. give me a break. got physics tomorrow :P

lol what were the harder questions asked?

Astrophysics is a fuss.. but gonna try and learn it tonight. How's your study going?

The derivative of a log function is log(x)= f(x)/ f'(x) so in your case, you would do the opposite. But the derivative of x isn't 3... however 3 is a constant therefore you can "take it out" of the function like the post above. Thus 3/x can also become 3 times 1/x. Now the derivative of x is 1...
