    Physics paper 31 , (a death call)

    No , the waves are passing through a gap ( the straight waves hit on obstacles) making them bend and therefore diffract check your book the chapter about waves.

    Beta is into the page (which means towards the north, hence upwards and the current flows to the left not the right as you will use the right hand rule because you don't know the current if they were asking for the force then you will use the left hand rule.)

    After you do that you just got the resistance of the two resistors what about resistor R how are you going to get it ? Look i used the total current and the total voltage(6v) to get the total resistance then i subtracted the total resistance from 1.2ohms and i got my answers , lets not turn this...

    Everyone is giving different answers so we can not take them into count , but we will get 3 marks for the working out inshallah :) so no worries.

    I used right because the current was uknown in this case.

    Pressure is the same across the oil , not across the pistons. Anyway's what is done is done :).

    Well piston Y had a larger Area and larger Force hence pressure will be less acting on piston Y pushing it a samller distance than piston X , that is what i wrote. Inshallah we will All get A*'s say Amen.

    At first i got 1.8 ohms as the resistance but then that is the total resistance of the circuit what i did was get the total resistance and the resistance of the parellel resistors then subtract both and i got a 1.1 ohms .

    Biology paper 61... DONE

    So she wrote exactly what i wrote mashallah , i just made a mistake in the nematodes part i lost 3 marks in that. The rest was hamdilliah good.

    Awesome notes for Islamiyat p2...Enjoy.

    Thanks for the notes i will check them out later on .
  17. Ahmedboombox

    some one.. plz upload sir.adeel jatoi's guess paper for islamiyat p1

    Don't stress it guy's just relax , i have just opened the book today and i suppose i will be able to work somethings out anyway's make sure you revise the verses and just follow the cirriculum instead of just reading everything. Peace

    Mathematics: Post your doubts here!

    For paper 4 , All you have to concentrate in is numbers which is always the first page (A lot of people make mistakes without knowing) , Area just simply practice it , The chapter concerning frequency density and cumulative frequency and we can not forget the probability (also alot of people...

    Mathematics: Post your doubts here!

    Well For the Question concerning the Transformation , I got a shear with y axis invarient and scale factor of 2 (1 0) (2 1) , I multiplied all the points by this matrice and i got the same exact points for the Image(shear) so i dont know why some people are saying X-axis is invarient.
