the explanation u just gave means that the current flows from x to the globe to y .. thats C not b .. unless my paper had a typing problem in it
lol?typical_azn said:i thought this would happen, u must have impaired vision, if you read it, it says electron flow, which means conventional current flows in its opposite direction.
typical_azn said:question 10 has many uncertainties, im not to sure either, it doesnt say wether its AC or DC,
That's an unfortunate error u've made there. The answer is A. What you have confused is EMF (given by B) and the FLUX itself (given by A). Since the coil is PERPENDICULAR to the field intiially, the flux is a max. people who put C mustve seen a graph of the current in a DC generator and gone from there.outlawjo3 said:I think i got the answer to question 8 --- B
For proof go to the 2002 HSC....QS 10
Very similar and the answer is B
Keep in mind that induced emf is proportional to the rate of change of magnetic flux. Therefore the question is essentially the same
Look where the coil is perpendular to the field
From that...the answer is B

You had to use pythagoras, which i did, but then u also had to realise that u dont plug in sin45 coz the B field is INTO the page so its always going to sin90. Argh (-1).

ahh fuk ... dammit ...ahh shit i did the same thing like you ... bastard
sorry dude i had C too but think about it.... u dont times it by sin 45 .... the angle is sin 90 because the field is perpendicular nayway.... yes u had to use pythagoras but it was sin 90jed.hamers said:Wanted to be smart and tell everyone they were wrong for #7. But as i read that had already been done. Answer is C = 0.6N. Have to use pythagorus theorum to find diagonal length, no just a simple sub in as everyone else is saying it's D. THE ANSWER FOR 7 IS C
Ok. I've found out that you're name is Lawrence.SureBluff said:who the heck are you guys?
I bet one of you is Lilster
I got 5 multiple choices wrong
FIVE!!!!
that's shocking man.
