np, good luck on exam! I'm having mine tomorrow, hopefully I'll get 90%+ this timetyvm, i understand it now.

Thanks
ok, first count the number of spaces between P and XY, you will find that you will find 3 spaces, each space represents wavelength. t=wavelength/speed and so the answer is C
here spacing means width of the slithttp://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Physics (9702)/9702_s06_qp_1.pdf
28 of this
iam confused by spacing isnt increasing spacing means increasing the size of the hole?
here spacing means width of the slit
u mean slit seperation right? the one in the formula lamda=ay/n in this 'a' right?
duuude, easy. full wave length from the diagram is six blocks, means 6x0.2ms, so 1.2ms, so 1.2x10^-3, but f=1/T f=1/1.2x10^-6, you will get 833.33 so about 830hz, is that the right answer?
ok each ocsillation occupies 6 squares so 0.2msx6= 1.2ms = 1.2x10^-3 s
first we find the resistance of the wiresplease help!
Excuse me 6Astarstudent... did u take ur physx p1 just now?first we find the resistance of the wires
0.005 x 800 =4 and because there are 2 wires which forms the loop so 4x2 = 8
now we find the V dissipated by the resistance so V= IR = 8x0.6 = 4.8V
this means that 4.8 will be lost during transmission
and the relay requires 16, so 16+4.8 = 20.8
hey sorry, I'm sitting the exam tomorrow.Excuse me 6Astarstudent... did u take ur physx p1 just now?
If so, and if u have the temperament to do so, can u kindly PM me the answers u remmbr?

variance 3, so taking paper 13Np.
Tell me how ur ppr goes then...
And out of pure curiosity, what variant are u taking?
