Thanks a lot for your help..
I don't understand part (ii).. why is the p.d 2.7?
It is the p.d across the thermistor !
We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

Challenge For Every one :S
I have posted the solution of this question before as wellChallenge For Every one :S
check out this thread.u will get the ans
W = QVsm1 plz help wid dis qs
(b) An electron is accelerated from rest in a vacuum through a potential difference of 4.7 kV.
(i) Calculate the de Broglie wavelength of the accelerated electron.
wavelength = ............................................ m [5]
(thid qs is frm w12-43)

number-12c(i) please dra graph for it
thanks and Jazak Allah Khairn
i think the answer's D?? (obviously you need to write the actual answer as well in order for me to know if i have got it right and only then would it make sense that i explain how i got it..)

obviously A
the answer is C .we should first calculate total resistance which is about 0.59 .From V=IR ,voltage can be calculated which is same throught the circuit.so by V=IR it can easily be calculatedcan anyone help me with these two questions
with working
thnk u in advance
SHM(simple harmonic motion)-motion of an oscillator where it's acceleration is directly propotional to it's displacement from it's equilibrium position and is directed towards dt position.What is the meaning of SHM? and what is Angular Frequency?
can some one help me with how to find PHASE DIFFERENCE between two points on same wave ... and how to draw a wave if eg .said another wave has phase difference 90 degree .... ??check out this thread.u will get the ans
a=2.8(check the graph)can some one help me with how to find PHASE DIFFERENCE between two points on same wave ... and how to draw a wave if eg .said another wave has phase difference 90 degree .... ??
