    Physics paper 31 , (a death call)

    f1 /A1 = F2 /A2 we had this in our book on that pressure transmission thingy

    have a look http://en.wikipedia.org/wiki/Series_and_parallel_circuits idk where you got the idea that voltage somehow magically divides in a parallel circuit lol its aginst the simple rules of electronics

    they wrote that pressure is same :p the thing is it has more area and volume so less movement

    i got my answer confirmed from multiple sources

    you need to wear a brain -_- read my post again there was one parallel circuit and one series circuit

    air is compressible so force not be affectively transferred

    sorry bro your answer is wrong

    you had to solve the question according to the values given if they give the current in one branch as 0.8 A its part of the question and doesnt affect the second branch

    you need to study parallel circuits and potential divider again have a look at my post i hope you understand V in parallel doesnt change

    no you had the current in one branch you had the voltage which was same in both branches current in one branch is not related to other u had to find the current by V/R so current in 2nd branch was 3A the total resistance across parallel was 1.2 ohm effective Resistance of circuit was 6/3.8=1.579...

    his answer is wrong

    6v since it was a parallel circuit
  13. B

    Physics paper 31 , (a death call)

    answer was 9.33 current was from p-q
  14. B

    Poll:Physics p31

    the answer was beta particles move outwards of page since the direction is reverse of the current and yes u had to draw magnet field and current it was for 2 marks 1 for each

    GUYS HELP 4 PHYSICS PAPER 3

    you can take it in this way R proportional to 1/A area of wire is pie r*sq* you half the radius the area becomes 1/4 so resistance increased by 4 times 16 ohms

    bio 31 expectations?

    yeah i think A* will range from 185-188 since both papers were damn easy
  17. B

    Physics paper 31 was it hard or its just me !!

    come on guys 12 page paper cant have that low threshold
  18. B

    Chemistry Paper 61

    exactly :D boiling the solution will concentrate the solution and crystallisation takes place

    Physics Paper 31 D':

    how did you know :p

    Physics Paper 31 D':

    very easy paper nothing hard just needed clear concepts
