i think in macmillan physics they talk about the significance of the effect of the electric field equalling the effect of the magnetic field on a charged particle... he established an equivalence to derive another formula: Force of B field = Force of E Field therefore qvB = qE therefore...

what we ppl at sbhs did was to roll a marble off a bench and photograph the trajectory using a video camera set to 25 fps (frames per second). This was in conjunction with a crudely devised graph of 5 cm spacings used as a backdrop...thus knowing the position and velocity of the projectile at...

btw happy birthday john!! i'll take a raincheck on those birthday punchees lol...can't wait to see u back at school~~ :P

thanks for clearing that up john....the explanation in jacaranda is fux0r3d....and i don't understand it.... but then again i dont understand braggs experiment either so any help again would be appreciated

well u havent really specified what units of concen tration you are using...but jims is correct in his (or her) use of molar concentration... other types of concentration might include grams/litre (the easiest since there is no conversion) ppm ppb etc etc...

yeah sure....when doing moment questions ALWAYS remeber the golden rule... the SUM of the MOMENTS in the CLOCKWISE direction = the SUM of the MOMENTS in the ANTI-CLOCKWISE direction... im not sure what aspect of this would be too hard...as ivre mentioned before if ppl want help what i...

yes maybe...but what you'll find rather is that this is the case with most degrees, right from arts all the way to medicine... yes u can study aeronautical at UNSW, and u dont have to enrol in adfa to do so....afaik....what it all comes down to is the title of your degree...because as i have...

hey do u do engineering studies? If so copeland has a section on it....anyhows what he says is that the major employerd in this industry is the air force, so what your employment would encompass would be the maintenance of their planes and the like...however australia has few employment...

you'll find that there r heaps of ppl here who are willing to share their knowledge with you...especially someone in youe position so thereofre, ask away...any specific questions and ill try my best to help you out~

Ok having read through the first section of the chapter entitled 'semiconductors' (twice over) i have to say, what are they going on about? I am totally confused as to what diffraction grating is, why diffraction patterns are significant and applications in determination of crystal structures...

err john ur making things waaaaay too complex as usual...can't u just accept the fact that they are packets of sound energy which bind electrons in a cooper pair together? as far as i know, the syllabus does not require to go into a terrible amount of detail on WHAT phonons since the emphasis is...

i hope i can help you out in some way....i myself go to sydney high where we have relatively good teachers...so I'd be willing to share ideas/notes...whatever...also U'll find that engineering studies is a subject which does not require much help from ateacher so if u stucj to a regimen of self...

i reckon this is one hell of a stoopid question....becuase its not really testing your knowledge about chemistry.... so therefore just rave on about something which you think theyd want to hear...jims raised a good point there about the fact that chemists usually specialise, so collaborating...

why is it a delicate balancing act? because you could just decrease the temperature and increasre the pressure indefinitely in order to 'theoretically' drive the yield to a maximum...but in reality this isn't the case because what you'll find is that although the yield does in fact increase, the...

THE BACTERIA INVLOVED ARE "ALICAGENES EUTROPHUS"....YOU MIGHT WANNA READ CONQUERING CHEMISTRY FOR MORE INFO...

yeah it is....just consider it as u would any other engineering course...without the specialisation...

true dat

yeah...its in medicine....uai = high

haha williaim still raving on about THAT course...?! altho i must admit...what with rampant medical litigation these days why would u not :P Oh well...another good excuse to study ur arse off for who knows how long~

but that isnt the case for med...even if u r doing say medical sciences...u have to start from bottom up unfortunately~
