I think I said mechanical failure of the voltmeter or ammeter would give erronous results

haha yeh as soon as I divided one by the other and got 8, I just couldn't help but smile. Such a nice, whole number haha

Yeh there really was shitloads on motors and generators -_-

What did people get for the orbital ratio? I thinkkk I got 1:8? or 8:1 whichever way it asked for it

But because the speed was so large, the distance it travels in one such is significant enough to make it (d) I think

Thanks for your input Aaron Judd :)

It would be (c) if it were standing still and emitting the pulse. it's kind of like the red shift of the universe expanding if that helps

Lol yep whos this?

So that's probably why I'm ranked 1st right? Oh Aaron Judd...

WTF for that developing electrical systems or whatever, I just talked about the external factors that had to be considered - i.e. a need to be transformed for safety, economic, conveniance etc. etc. so a system should be AC Didn't even MENTION a "Scientist", how could you even adapt...

If you used the time dialation formula for 5 you got (c), but since the ship is moving away at a constant speed it's gunna take extra time for the signal to get to earth - so the answer had to be (d)

Wow you're modest -_-

Je ne suis guere pret....

Well I guess we're not doing Quantum Theory here :S The guy on the phone said basically what you just said, that we're not expected to know anything more so you can just say it hits the lattice

Just called up the HSC advice line - they do yeh

I'm pretty sure it does. Otherwise he's saying that if you have a metal free of impurities it wouldn't encounter resistance? The lattice vibrates due to thermal energy, and these vibrations impede the free flow of electrons through the metal through collisions which scatter the electrons...

Yes they do? The vibrations of the metallic lattice increase the chance of an electron colliding with it, and thus resistance increases with temp? Next Question: Describe the BCS Theory of superconductivity

In your course you had to gather information to explain how induction is used in certain applications. With reference to TWO appplications, describe how you assessed the reliability of information you found. The principle of induction is used in: (a) Induction Cooktops - AC current is fed...

If it's a 6 marker, do 6 dot points. but make sure they actually contain info in each. it's easier to keep track of how many points you have raised/still need to raise

I believe it was not counted in the marking because the question is ambiguous - it doesnt say whether the astronaut has slowed down yet or whatever
