AoA,
waalaikumassalam wr wb!AoA,
Q1:
In equatorial orbit means that the period of rotation will be equal to period of rotation of the earth
That will not fulfill the purpose of GPS technology as the satellite will always be at the same point above the earth!
I hope you got it.
Q10(a)(i):
In fact, its quite hillarious the conflict b/w m.s and examiner report.
Here, i will attach both snapshots:

waalaikumassalam wr wb!AOA.
Q1.c) well m not sure about this part, but I will like to share my opinion.
As far as books and application booklet ix concerned they state away says that a geosationary satelite rotates on the equator and therefore itx nt possible fr it to cover polar regions. thatx the only reason polar satelites are used fr communication in those areas.
now if the sattelite is a little inclined so it may be possible fr it to send and recieve signalx at the top of the earth(polar region) as when we need to pick some thing from a higher position we stand on our toes(making an angle from ground) to have excess to that furthest position.
the m.s also states that having an inclination of 55 degrees make the gps able to reach to polar areas.
hope I am able to clear mY point oF VIEW

JazakAllah khairen for solving the other ones..many duas 4 all....
PAPER 4 doubts...
Nov 2003
· Q:4 c Can you show, how is the less ripple represented, please.. :s
June 2004
· Q:4 c reason for the answer...· Q:6 last part..· Q:8 iii who said we didn’t use them? :s
June 2006
· Q:2 b (ii) how to do?? :s· Q:6 c what do I write for this?
· Q:7 Can you answer the complete question, I couldn’t do this one...Nov 2006
· Q:3 c what to write? :s· Q:6 a (ii) How do the diode works then, normally...isn’t that the way we usually connect? :s
June 2007
· Q:3 d (i) Why is the answer zero? Just to confirm, is it because E=F/Q and F = ma so E is proportional to a...and hence a will be max. when E is max? is it?· Q:4 c (ii) How’ll the diagram be? :s· Q:7 b I don’t get why the damping is reduced...i took it as, resistance is increased, more power dissioated, hence more energy losses...so oscillations die off quicker..but it say damping is less..:s confused..· Q:7 c (iii) can you give some examples? :sNov 2007
- Q:1b(i) I don’t understand how to do this..i did see the mark scheme but still I wanna know why to do this..or how to arrive at this..:s
- Q:4 b need explanation + how to draw..?
- Q:4 c (ii)I don’t understand, can someone plz explain me..
- Q:4 d explanation... :s
- Q:5 b (ii) Which area do I determine...
Thnx, missed that point,
Divide the area into various figures such as squares, rectangles, triangles and trapeziums. Keep adding up these areas and when you reach a point that no shape is possible, simply calculate the number of small 1 unit squares left!
exactly...Divide the area into various figures such as squares, rectangles, triangles and trapeziums. Keep adding up these areas and when you reach a point that no shape is possible, simply calculate the number of small 1 unit squares left!
Add them up and multiply with whatever scale is given!
I just wish this type of question doesnt come, and if it does, i will do it after im through with the rest of the paper!exactly...
i know it's too annoying, but make sure u don't leave even a single square
they expect u too use all the squares!
but then doesn't this change the time for charging and discharging...shudn't we keep it the same..?Thnx, missed that point,
J07,
Q4(c)(ii)
Something like this, sorry its free hand drawing
Assalamoalaikum wr wb!!http://www.xtremepapers.com/papers/...and AS Level/Physics (9702)/9702_s05_qp_4.pdf
q5b) a detailed explanation plz that how will be the graph and whY ix the graph shaped lyk that??
q6b) all partx including bi, bii, biii,
here again m confused that hoW wil grapHx frmed and what phase angle diff.?????
explain here that why graphx are forming lyk that??
plx pay alittle attention here as well guyx??
It should'nt because the capacitance is the same.
