u know mass of ice melted in 10 min.....from this u cn find the mass of ice melted in 5 min just due to atmosphere....now subtract this value from 64.7 and apply Q=mLf

WHY CANT MULTIPLY THE OTHER VALUE BY 2 (64.7*2)for 2 b iii

I would sugguest, waiting for questions to be solved first then post more...Because you are pushing your old questions up and people may not notice it.. Thank you.
Question 2 c ii)
use fleming left hand rule
6 c) I proportional to r , take ratioshttp://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Physics (9702)/9702_w09_qp_41.pdf
6 (c) , 7(c) (ii) 2 , 8 (c) (ii)
2 c ii) was canceled from mark scheme.http://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Physics (9702)/9702_w09_qp_42.pdf

2 b) PV = nRT where n = (N / Na ) where N = Ne^-lambda x t !http://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Physics (9702)/9702_s09_qp_4.pdf

2 b iii) explained above
two different formulas, mv^2 /r and m r w^2... depends on what you are using!ok a simple questin here f= mv^2/r this means that centripital force is inversly proportional to radius??? ryt??
now here in this paper, question 1 c)
it is stated that centripital frce will increase as radius increases???
great confusion

question was asking for 5 minutes!WHY CANT MULTIPLY THE OTHER VALUE BY 2 (64.7*2)
u will apply the formula f= mrw*2 not the you hav stated but we r talking about the angular acceleration so this equation is applicable here so according to this increse in radius mean centripetal force is also increased. I hope it helps you and clear your problem.ok a simple questin here f= mv^2/r this means that centripital force is inversly proportional to radius??? ryt??

to provide coverage at the poles!Q1 (C)
U EXPLAINIT WHY??????????to provide coverage at the poles!
Q1.c) well m not sure about this part, but I will like to share my opinion.CAN
U EXPLAINIT WHY??????????
FOR COVERAGE AT POLES 23 DEGREE IS THE ANGLE.....ISNT IT???
YEAH I UNDER STOOD THANKS....................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
In Remote Sensing (in the document I uploaded) you have everything you need - from page 14 to 26 I thinkguys i am really worried about medical physics i dont even know a bit about it can anyone please help me on it and guide me what to learn any important points and if anyone has made any good notes on it so please post it here !! thanks in advance waiting for the reply soon
thanks for it i know its in the app booklet but i need simple notes to learn them as it is very confusing in the application bookletIn Remote Sensing (in the document I uploaded) you have everything you need - from page 14 to 26 I think
With the application booklet I got some main ideas and then got to understand everything much better through answering past papers and then checking the mark-schemes...thanks for it i know its in the app booklet but i need simple notes to learn them as it is very confusing in the application booklet
