    PLease Please someone check thsee q's of pak studies p.1:

    actual heres the thing The best thing to do is to start by explaining the thing thats asked by the question ( in 14 mask question ) . Like if the question is "greese cartillage incident was main reason for war of indepence blah blah blah " first explain the greese cartillage incident . then...

    Maths help

    3y=-4x+6 Y=-4/3x + 2 Replace x with 3 Y= -4/3 (3) + 2 Y = -4+2 Y = - 2 so B is (3 ,-2) but i just realized something , B can be of any value and for different value of B mid point would differ. hmm so this cant be applied . :) CAN YOU PLEASE TELL THE YEAR AND QUESTION NUMBER OF THE QUESTION .

    Well you wind mid point of any line by , y2+y1/2 x2+x1/2 you can find b as you now know what the k is , You know that the graidet is -4/3 .Just replace one random number of X and youll get your Y and hence you can use the formula to answer it . If you want ill answer it on the forums for you...

    Your right :cry: i should kill my self now :)

    Frequency does show that doesn't it , hmpf :P but time period is time for a single wave :D if you no how long one wave takes you , my friend , have the power to change the world :D

    0.5 not 5 . and after skiping a sucsessive crest i think x was . i really dont remember . Should nt we just forget about it , its not like we can change what we did . dont worry your answer is . IA we'll get A * . :P

    its inter changeble , to find out time taken for a single wave :D

    physics paper 1,2 ........can we discuus da papper nw?

    ACTUALLY WRONG METHOD BUT SOME HOW RIGHT ANSWER :S . The drawing was not drawn to scale . t=1/f , were t is the time taken to make one complete wave . as a result it came to be known it takes .5 seconds for one wave . hence it takes 1 sec to make 2 waves so you make mark postion new one wave...

    Actaully the X mark was one wave skip . You had to use f= 1/t . :D

    You could have wrote use a fan or something like put it in a freezer :D it makes sense :) you can always try putting a live wire in your bath tub and see if it cools down or not :D science is all about testing ........ and not dying of electricution

    Yes Yes . will you please stop reminding me of the stupid mistake i did. i mean i wrote this answer , but i had like a extra 20 mins so i spent more time thinking on it. one thing led to the other , and before you know it i marked p/2 as the answer :)

    Hardly . Everyone is hoping for a distinction in physics :P Tough competition .(Got 1 mcq question wrong yet, the so called question daredevil dubbed as seperating a distinction from other A*s )

    Help pleaaseee..

    The examiner would probebly be an old man with no life :P He has the time to check all the questions .

    oh common , why would be put a wire in water -_- . WHY ! WHY WHY!!!! and i really dont get what your saying about the particle question . Your saying particle movement was stationary ? that can't be , if there is a wave going there will be particle movement . and the last part for the X...

    physics paper 1,2 ........can we discuus da papper nw?

    And thats the only question i got wrong ;( Anywho distinction isn't determined according to a single question but over all performance :P that last line was probebly the only thing you said wrong !
