ah i think he missed ma secont question... anyone else know??

Legend... so what that means is that once they are put together...a depletion zone forms ova time. Then afta that, as a potential difference is supplied...holes and electrons move (as normal semiconductors). Am i right am i right??? Oh yeh one more question. When hertz discovered...

Damn not as if frikn MRI isnt hard enough!! nah i dont think we really have to worry about actual values...they wouldn't... WOULD THEY?!!

.....come on boyz and girlz...someone..?

Nah alot of those STA papers have a lot of incorrect answers to them. N id think that wuld be another.... How ironic, pfftt...teacher's association ma ass.

wtf???? is this supposed to be in the "ideas to implementation" forum?!?

what plank done was explain the black body radiation curve, because at the time many scientists couldnt. What he said was that, the energy raditated (or absorbed) by a black body was not continuous ("radom"), as classical phys suggested but rather is absorbed in packets of energy called...

oh u do med too? Hmm...well i dunt really understand it like in full detail, but yeh im ok so long as i read it a couple times tomoro. I dunt know wah that mHz thing ur talkn bout is tho

yeh ok i sorta get yah...Are you talking about the semicondutor diode sorta like "running out"? And so i dunt understand wah heat and resistance has to do with it... could one of u's breifly sumarise wah u's are talkn bout? thanx

hey there... sorry i dunt know what you exactly mean by 'depletion zone'?? thanx.

yup since the electron passes through the metal lattice the cations are attracted to the path of the electrons. SO as the cooper pairs join together, it causes a distortion in this lattice and the cations begin to vibrate about a position. This vibrational (sound) energy is stored in phonons (...

HUH??? Fired at electrons into a crystal? wait a secont... Braggs experiment: he subjected a metallic lattice to X-rays (small wavelength meant that the waves would reflect off the atoms)...and the reflecting waves would undergo superposition interacting destructively and constructivly so...

XAYMA....you are so gay cuz, its not even funny. I understand u like showing off and shit...but y wuld u mention a universal motor if its asking about AC motors??? U just confused the hell out of everyone unnecessarily. Im with the ilovechildren person (U ROCK!) Peace

I get you....sort of, but then again my answer was an attempt to explain this. y dunt we agree and nod our heads in satisfaction? :)

I know your the one tha asked the qn. but u mind sharing the answer with us all boof-head?

Hm good point...BUT (aha!!) Iron is a ferromagnetic material, that is iron is best for intensifying the magnetic feilds that are needed to create these eddy currents. (thats why Iron is used a core for transformers). Im not exactly sure about how good Aluminium is when it comes to intenisfying...

wait a secont... do we have to know the experiment that Faraday carried out?? and what dot point are you guys talkn about?!

well actually our home power supplies, (240V)...is an alternating current, and the frequency of oscillation is 50Hz. But nope nuthn u need to know at all.

Oh yeh i forgot about qn 2. F(magnetic) = q.V.B. where q= charge of particle. v = speed of particle (m/s) B = Magnetic feild. However i think they did remove this from our syllabus, but i learnt it anyways because J.j. Thompson used it in his experiment. Peace out.

5. AC Vs DC The relative advantages and disadvantages of AC and DC generators relate to two features of their design: DC generators use a split-ring commutator, while AC generators use slip rings; and in DC generators the output current is induced in the rotor, whereas the roles of the rotor...
