when its stopped, no change in magnetic flux hence no induced back emf in the motor according to Faraday's law of induction. the current of opperation is the current supplied minus the back emf ... when there is no back emf the current of operation will be really high... which opposes to when a...

uhm it really depends if you go to selective school or not... most kids at my school are dropouts. if you go to selective school and they offer standard then go for it.
it doesnt really matter to me that much, i find 4 unit maths like any other subjects. i did it because im better at it than other subjects and it will give me a good uai to go to uni. so the level of maths in high school doesnt worry me because like any subject if you dont practice over a period...

cant believe its 1 mark ... if i had this question is exam ill probably leave it out.
nvm. i got it ...
thanks if anyone did try
all my friends in standard regret dropping down so dont do it... the reason is that the teacher is crap because all the good teachers are chosen to teach advanced and the students are 'dumbasses' ... since english is compulsory, people that want to do year 12 but dont care about going to uni...
yeh so true (sarcastically) ... like seriously all my teachers make their own exam paper ... and this is how they do it, they get the pamphlet and order it ... stop complaining ppl i go to a public school thats what all teachers do ... as if they make their own trial ... who pays them????!!! and...

ahha ... got it so the direction where the positive charge is forced to is the postive end and the negative charge is forced in the opposite direction to the negative end... right?
thanks
hey congrats great results ... looks like you will kill the hsc for sure, but i have to agree that question 7-8 are so random in the hsc ... i have been doing so many trial past papers especially cssa and just started doing hsc past papers and looked at question 7 and 8 and was like wtf!!! but...
hmm... i dont get the bit where you said the electrons receive a force pushing and moving them to A. Each time i revise physics i always get stuck on this bit ... confusing the blood hell out of me ... please help
you are allowed to if you proved that S(1) and S(2) is true or something like that ... you know what i mean... so like if you assume that its true for n=k and n=k+1 and you proved true for n=k+2 then its true for S(3) and so on ....

getting an arnolds cambridge 4 unit from school and learn to solve it by yourself - priceless
3/4 of the induction exercise in the cambridge has those types of recurrence induction questions,
we only have harder 3 units to go ... but i finished it at home already. also is the extension part of the cambridge 3 unit good for building harder 3 unit skills?
damn impressive vafa you should aim to get top of the state, i got 78/84 too i topped my grade ... i didnt get the probability since i am so shit at them
