By"rotational" motion. do you mean the speed at which the Electromagnets around the rotor switch on and off?

are supplementary texts the related material of your own choosing? or what? just want to clear that up

well . i think... i think you dont really have to classified them as internal and external but the influences are , i think -Maintenance workerers unhappy with the decision by qantas management to shift maintenance jobs oversea to singapore.(reducing labour cost) -after september 11...

phew, got 17/20 for my Managing Change and Financial essay. man, i wrote 7.5 pages and prepared it for a week before. my classmates did it the day before the assessment and got 19/20. :vcross: ohe well, at least with 17 is still get to keep my fourth position in BST i was really...

well ok, but for the induction motor. once you give the rotor a push. it will start to rotate without anymore energy input. is this correct ?

xayma thanks for explaining how the induction motor works. But i dont think you have answered my question. but for the speed of rotation part. You said that speed of the rotation of the motor cannot be controlled. but what if you control the rate of turning on and off around the rotor...

and also can somebody tell me the difference between Magnetic flux and magnetic field intensity?

ok let me get this right. with induction motors. no commutator or split rings are used because the current is induced onto the coils.(by a magnetic field) the stator is a circular piece of metal with 2 curved pole pieces(electromagnet) to which the current is supplied to. the current on...

Hi people you know how acidity of oxides decrease across the group from left to right basic to acidic wat i dont understand is since group 2 elements can have oxidation state of +2 eg Ba(OH)2 wouldnt barium oxide be more basic that KOH?(cos it has 2 OH) but basicity...

alrite alrite I know you people are talking about the substitution method but this is as far as i got a=-3-2x a=-1(3+2x) since a=-n'2x let x=3+2x right? now what? I am a bit slow so please bear with me

is this kind of question ever likely to be in the HSC if it is..........

Evaluate the role of financial management(somebody help) so i got this topic i need to write an essay about Evaluate the role of financial mangement in achieving the goals of the business. what does evaluate exact refers to? compare or what? and i dont know how i should go about it...

do the following Height=(VsinQ)Square / 2g (u should know this equation by now) which is 100= (VsinQ)square / 19.6 rearrange 1960=(vsinQ)square rearrange Root(1960)=VsinQ so VsinQ=44.5 then we work out the half time...

i totally agree with you all. All i am saying is that, had the first question been just more normal and picked out of those millions of exercise i did(which does not require the unnecessary steps,cos they just asume u know). my result will be alot different.... i just needed to tell...

ok . im about to ask a really stupid question but here it goes A current is a flow of electrons. how does then a conventional current flows the opposite direction of the Electrons and also how does current have postive charge(right hand rule), i thought a flow of electrons should...

chicken. yummmmmm...... am i the wrong thread? man i need to a new pair of glasses

one big question or series of small ones?

how many questions from option topic will likely to come up in the trials test?

my chemistry teacher made us put in 20 cents everytime we swear so that we can get pizzas at the end of the term. he teaches phy and chem.... so there goes the quality of education in our school. he is a funny man cos wait...am i in the wrong thread? arrr , just pretend you never saw this

ha i am so lucky, our school dont do any pracs, my last assessment is on a physics report. got all the time i need
