damn straight..our school has a physics class of 6, not one girl.......and a chem class of about 25, 6 of them are guys....ironically the same ones who do physics......

it souldn't change it, area only changes torque, the length of the conductor in creases the force but by the equation I=neva length plays no part in drift velocity. on ly, current, area of conductor as viewed from a CROSS-SECTION, charge and no of electrons....right?

there have been other spin-offs from space too remmeber, microwave ovens for one......dervelopments of advanced propolsion systems. don't forget ego expansion and the cold war/space race..... and if youre talking about the elective topic, this about the origins of the universe, projected life of...

yeah...it just followes the oppostite of the right hand rule..... the batabase....hmmmmmm. seems like i'm encountering a large resistance, there must be a large current flowing through the database!

i hope we get a q on this.........

@#$#% database errors........... then v^2=30^2=44.198^2 =53.4ms

s=.5at^2 so 100=4.9*t^2 so time=4.51sec... v=u+at so v=9.8*4.51 =44.198ms:D v^2=30^2+44.198^2 so v=53.4ms

although you're travelling away from the light source at c, realtive to you light still behaves under normal conditions at c, thus reflection refraction etc are all normal. this means you would see your image as normal. but an observer in another frame of reference v=o, wouldn't see an image...

stupid mistakes on both......cheers!

thats what i thought when i read the answer.. this is what i got.... a=v^2/r a=15*9.8 =147 v=900km/h^2 =10497600m therefore i get a radius of 71412.2449m! i know that sounds wrong! how'd you get 425m out of the same equation?

actually mine looked more like this...... superhuberts super motor my real one caught fire in my room, it never quite worked the same again.....

you could never see a changing magnetic and electric field not just because both forms of radiation are invisible, but because you can never travel at the same speed as a photon of light because no matter how fast you go, light will always travel at 3 10^8ms relative to YOU!

i've got two practice q's from space and motors for the game, i can't get the same answer as the given solutions. any ideas? 1.an aircraft can withstand the stresses of a 15g acceleration (ie an acceleration 15 times that of gravity), then what is its minimum turning radius at a speed of...

light is a constant for all observers, so in the train light still travels at 3 10^8ms, so there would be no difference to looking in a mirron at o ms

obviously induced currents cant really flow in a motor because there is already a current flowing. but it has its own version, back emf, this opposes the supply emf. induced currents occur whenever there is a conductor present in a changing magnetic field. Thus by lenzes law, it will flow in the...

damn, after reading the title i thought we got to vote on whether the exam sucked before we actually took it..... but that wont stop me, I THINK THE EXAM SUCKED, WHAT ABOUT Q 12? WHAT THE HELL WAS THAT? WHAT DID YOU GUY'S THINK? DOWN WITH BOS, DIEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE...

then again, if you ONLY use those 3, there's no way you could answer most questions...

"excellence" is a state that one achieves when thier ego grows too large.....

I'VE GOT IT!!!! sailors are all stupid... they wouldn't have believed him that the cannon ball would drop on the deck, they would have thought it would have landed behind the boat....stupid sailors....I'll bet Galileo had hell to pay when he prooved himself right.........:D
