I put electrons in condution band moves towards the positive terminal. The holes in the superconductor enable movement of electrons in the condution band. I really dont think they move in the valency cause there is always an energy gap and doping just increases electons in the conduction band...

The 06 qsn was a trick 4 pple who did not look care fully e.g ME yh its perpendicular to the current carrying conductor as everyone just said...lol

was just looking at the dt point and trying to remember.

Is drift velocity the velocity of electrons as they move through a substance. And the velocity is rarely the same as colllisions with positive charges usually reduce their velocities. Not sure cause the books i used didnt seem to go into much detail abt the drift velocity in super and semi...

AM LISTENING How is it a lie it seems perfectly logical

thats amazing whoa!!!!!!!!!!!! lol

there is an okay chance unless they get a better band 3 question they should.

The main reasons of using cyclohexene and cyclohexane are: >colourless >liquid at room temperature and not as volatile as other common liquid hydrocarbons. plus in ua risk assessment u should note down that cyclohexene and cyclohexane should not be disposed off directly in the drain as they...

Geo essays are pretty predictable except the economic activity one. I am doing tourism and have to combine perisher in my essay. I think topic 1 and 2 should be alright.

harder 3 unit is always examined in 4 unit except in our 2008 exam we didnt have much if any. yh we dont have a topic for harder 2 unit but its assumed knowledge.

i think we need to know finance qsn as its considered to be harder 2 unit. like when u do 4unit harder 3 unit.Although Harder 2 unit is not examined as much as the 90's.

(i)there are 5 men/ for a doubles game there is 5C2 ways of choosing 2 men or women. Then after this there is only one way to choose their couple. but then they are not to play on the same side. u can think of this as an arrangement where by if the man is first then his wife is not to come...

has anybody attempted these papers? Whats ua thoughts on them?

cos(-2pi/3) is a negative. His solutions show a positive. this is because -2pi/3 is in the 3rd quadrant where sin and cos are both negative

with those marks u would be the first guy to get 120 since the only guy who got it. hahah ua bullshit marks lol

the pple who predicted that 4unit was going to be a walkover were shocked. so u dont noe wat to expect prepare for trouble.

marks(15)(11)(13)(14)(15)(12)(13)(7) no time for qsn 8. these marks include stupid mistakes and probable marks deductions.

question 7 and 8 were okay. q 7 wasnt bad although 8 never had time to think.

i got 3 lol. the answer is 3 am pretty sure.

Be prepared for anything. it can be hard it can be easy who knows????
