crypsAnity:
It would be the same as the time base on then right???

Exactly man.. thats what i thought.. ohh.. I didnt get it from the book .. ts these notes by some guy called
prof A.S Ibrahim .. got it off from some guy in school who had em.. anyhows shoudlnt rely on them much see.. anyways
I have the Hodder Murrays's IGCSE Physics by Tom Duncan and Heather Kennet .. hmmm love tht one...

anyways.. thanks a bunch.. i get the y voltage thing now.. =] u best of lucks for exams mate!

Semiconductors have in common that their resistance goes down as temperature(thermisyor) or light level(LDR) goes up. A transistor is basically an electronic switch and a diode rectifier changes ac into dc

hi. Can anyone please solve question 1 (c) in m/j 2008? First variant paper. I don't really understand what you do after you multiply mass by gravity. I got the answer 500 N and I cannot figure out where I went wrong. Also I would appreciate it if anyone could explain to me how to predict the direction of the force in question 9 part c) (ii) in the same paper.

Thanks.

Enia:
wait actually never mind about the first question...I'm an idiot and I just realized my mistake xD. Sorry!! (in case, anyone is curious I did the mass in grams and not kg so I got it wrong =P)
