    Physics, Chemistry and Biology: Post your doubts here!

    For the first one yeah i guess you are right, they don't cross. Also fire thing i thought it might happen because if a spark it will cause a fire but that isn't possible (after i asked my bro) , a fire will only be caused if it touches something that can cause a fire or if a high current passes...

    Physics, Chemistry and Biology: Post your doubts here!

    In physics: Do we look at direction of current as conventional or actual? This just confuses me when i would like to mark an answer according to that.

    Yeah man that is wat i said, but don't you think they accept both answers , wtih multiplicatoin by -1 or without.... ?

    Mathematics: Post your doubts here!

    it is the same answer as the one we have they multiplied the answer by -1 so the answer is similar ,and give the same answer if you try putting a coefficient of x If say x was 2 (5-2)/3 = 1 , and in our case 2-5/-3= 1 mark scheme is never wrong buddy ;) ... well mostly

    But dude btw you should be knowing functions and these stuff before going into the exam. I suggest you give a quick look into math notes ;)

    Oh yeah lol , u are right , srry i am a bit sick today :P so yes y-5= -3x and F^-1(X) = y-5/-3

    Mathematics: Post your doubts here!

    Ok... When you are dealing with functions and you want the inverse of a function (i.e : 5-3x) , you have to do the following : 1- change f:x into Y. So it will be y=5-3x 2-make x the subject : y-5=3x(moved 5 to the other side ) so x= y-5/3 3- Final step is...

    Look the easiest way to think of it is this way: 5:4= 5/4 . so when you multiply 5/4 * each measurement it will give you the larger measurement. 5/4 * 44 = 55 5/4 * 32 = 40

    I have a doubt in chemistry... In Paper3 October 2006 , question 7 a (ii) Shouldn't the final point be lower than than that in the original reaction, as he is using ethanoic acid( weak acid) so it will give out less hydrogen ions? But in mark scheme they said said same final point, why is that ...
