    aw man i got 1:2

    Physics P-22 GT.

    i think it asked to show what happened to voltage across y.. when variable resistor increases... i decreases since resistance across AB increases so a greater proportion of the voltage goes to AB and thus less amount of voltage goes across y

    Dude I did 22 and there was no such question like that

    V21 or 22? And I'm sure there will be ecf so most probably if ur method for the second part is correct u will get all 3 marks but loose 2 for incorrectly counting the wavelength

    ya it was okay.. except that ratio question.....that was weird

    Yup since the wave is already at 1/4 now by adding 1/4 it becomes 2/4 so it's a horizontal line

    OMG thank u! Understand it perfectly now okay so if we calculated time Period and say it was 2/4 not 1/4 we would just draw the exact same thing right but since it's 1/4 we draw a horizontal line

    The nicotine was the one about damaging the artery walls right..

    How did your Biology Paper 12 go?

    Yay!! I thought I got it wrong coz I forgot to read the part that said it's magnified by 400x but hopefully A is correct

    How did your Biology Paper 12 go?

    Ya I chose A as well.

    I'm not sure but it was something like which one related to t and b lymphocytes is not correct
