    Physics, Chemistry and Biology: Post your doubts here!

    Explain what is meant by the terms analogue and digital, as applied to electronic circuits. Found this question in a past paper in physics, I know analogue, but what is digital. http://www.xtremepapers.com/papers/CIE/Cambridge%20IGCSE/Physics%20%280625%29/0625_w10_qp_32.pdf

    Physics, Chemistry and Biology: Post your doubts here!

    Not sure if I'm right, but because potassium is very reactive so it stays in the solution, so hydrogen is given out. and sulphate stays in the solution (don't know the reason behind this), so oxygen is given out. EDITED

    Need help in these question, thank you (explain the way to solve, and if you use any formula please don't use symbols, use their meanings F = force, etc.. thank you!) http://www.xtremepapers.com/papers/CIE/Cambridge%20IGCSE/Physics%20%280625%29/0625_w11_qp_31.pdf 3b (ii)...

    Done with Paper 6 chemistry = =

    To tell the truth, I was sick so I didn't really study hard for this exam, I solved the whole paper but I was unsure 90% of my answers.

    Done with Paper 6 chemistry = =

    When I left the examination room, most students were saying it's easy and they will get between 50 and 60, I did very bad in this exam, but nothing can be done for it now, better to study for physics in friday (2nd hardest subject for me, behind chemistry) and study hard for chemistry paper 3.

    Maths P4 and physics P1

    Both papers were easy overall, but I was not able to solve the sequence question in Math P4, I was not prepared tbh, I focused on physics and forgot about math, but an A* mark is very possible, because I did great in P2.

    @slayer very easy, draw a line (that covers all the the graph) between a point in the triangle and it's corresponding point in the image, then do it again with another point in the triangle and it's corresponding point in the image, the two lines you drew intersects at a point, this point is the...
