lol thanx that's betterahhh sorry sister! better now?
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!

hmm okay.. I just looked at the markscheme though and it says "lags behind T1" .. I really hope that means we draw it after T1..I'm quite sure it's wrong.
See for example the last paragraph and the corresponding graph here (I know it's about the pendulum but the concept is the same):

Someone answer this please
Here is the pic and hope it helped you...If it helped you then can you help me with few of my probs?Please someone solve Q.4 d (i) and (ii)
http://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Physics (9702)/9702_s07_qp_2.pdf
With explanation and diagram of-course. Thank you!
In part a, draw a continue the dotted horizontal line from the original alpha path before it is deviated.Then draw an angle b/w the horizontal and the deviated curve. As for part (b) this alpha particle B is also deviated away from the nucleus but the extent and angle of deviation is less than A because it is further away........

i)Amplitude is 7.6mm which you can see it from the graph (the highest displacement)can anyone please post the solutions of these two questions.regarding progressive and stationary waves...do post the answer to the graph as well. Please View attachment 11254View attachment 11255
ya i wont da graphs too pls make them !!!i)Amplitude is 7.6mm which you can see it from the graph (the highest displacement)
ii) 180 (This is 180 because, one graph is completed in 80cm.....So in 80cm 360 degree is completed. So there is a phase difference of 40cm between the point. So it is half of 80com and hence it is half of 360, which is 180.......Or you could use this formula- (40/80)*360 which is the normal formula of phase difference)
iii) V=frequency * wavelength
= 15 * 0.8
=12
(b) This one i have to show you by drawing....if you are interested then i can show you
(c)
i. Zero (Since they are on the same wave and phase)
(ii)
Antinode- A region in which two amplitude are at its highest point in opposite direction
Node- A region where two waves intersect and have no displacement
(iv) Again, i have to draw this...if you are interested then i could give a separate PDF for this by drawing in computer
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
