    Aether Question

    Yeah if you look in the 2003 marking guidelines for Q16, (a) or (b) you'll see that they said that many people listed properties of the aether, and not of the aether model, which is what was required. I think SuccessOne described it pretty well, CBA looking there atm though.

    Transformers

    Hello, I'm having problems calculating the current that occurs in secondary coil. The equation is Vp/Vs=np/ns... So since V=IR, shouldn't Ip/Is=np/ns, since the R cancels out? But for a question like below, I get an incorrect answer. But if I take the inverse of Vp/Vs, the equation works for...

    They might be imaginary :P

    Curve Sketching!!

    Okay thanks... Then answers are wrong, not suprisingly for Maths In Focus.

    Curve Sketching!!

    Hello again, One last question... for another one. For the curve y=x2/(x2-9), are there any horizontal asymptotes? Because as the lim x-->+/- infinity y = 1 ... Did I do something wrong? Answers appears to show that there's a horizontal asym. at y=0, but y can equal zero, when x=0, so...

    Curve Sketching!!

    Hello, I'm having trouble sketching y=1/(x2-16) I find that there are points of inflexion with y''=0... But they seem irrelevant (they're not shown in answers). I'd appreciate it if someone could help me. Thanks

    How do you think you went? Any chance of your results being imaginary :P (Sorry couldn't resist!!)

    Fitzpatrick isn't that great... I find Coroneos much better.

    That's not Maths in Focus... That's not how the EX's are titled in MIF.

    Should I do this option module?

    My teacher has done electrical engineering in university, so I'd imagine he'd be able to mark it?

    Should I do this option module?

    Well you see, the reason they do Q2Q is because they think it's the best suitable topic for when we go to university or something. And our class at the moment is 6 people... But there are 2 other classes of about 17 in each.

    Should I do this option module?

    Hi, My school does Quantum to Quarks for their HSC option topic, but I'm not really interested in that stuff to be honest... Well least to say, it doesn't sound interesting. I however do have an interest in digital systems (like computers, sound mixing, etc). I'm known at my school for being a...

    EMF calculations

    Hello again, I have another question.... Are RMS stuff now out of the HSC Course? Because I remember that it was in prelim. Sigh, it would be so much easier if I could get a list of changes from the 2000 syllabus!!

    EMF calculations

    Well I know in Chemistry EMF is pretty much voltage. But I think it's different because Chemistry deals with electron flow (galvanic cells) but yeah I'll wait for Trebla.

    EMF calculations

    Hmm okay thanks... I don't think the syllabus has any reference to EMF (but does to magnetic flux). What is the difference between EMF and voltage?
