i am 99% sure the diode was c

and madee yes because its an ERROR CARRIED FORWARD!!!!

wat makes u to sure ????


JOKE????

R U JEALOUS...OR WAT>>>>

CUZ I KNOW HOW A BRIDGE RECTIFIER WORKS~!!!!!! ;D ;D ;D ;D ;D
ha ha gud joke dude but still i mean vry few ppl wrote c
hey im not jealous alryt i was jus asking u a question
some people sleep to dream while othrs wakeup to follow dem im the second type how abt u

I put the medium A, because the ray goes AWAY FROM THE NORMAL when it passess from more dense to less dense(from medium A to air)
I hope its right :-\

the refracted ray wasnt 90 degrees so it cant be 42 and has to be slightly more at 43

since 21 hours have past, i'm sure by know everyone on the planet have taken the test

so how was it
By the way what was the mass and the fraction on the energy question


i got 1/8 for the fraction thing....and wat did you get for pressure question when they asked wat the pressure would be if the area was doubled? ....i halved the pressure....and the diode i said D  ::)

yeah i think i put D for the diode thing, but apparently it's wrong...idk!  :-\
oohh...for the pressure thing, they said the area was doubled, but the depth was the same yeah...so the pressure should be double too, i guess, odds are i may be wrong! :P
the fraction is 1/8 but i didnt get it... >:(
