    yes! we are lucky............. kai humaray syllabus ki 47 equations main sai aik kum hogai! :p :D . . . (by the way, 47 is just an estimate! :))

    resistance decreases as temperature increases, and vice versa. Thats all u have to know i think!

    this was a tricky question. I got the answer wrong at first too! see we all know different properties of images formed by converging lens! this question asks about a DIVERGING lens. The properties of image formed by DIVERGING LENS are : Virtual(same side of lens) Upright Diminished Closer to...

    you were correct there! i found out in a book where it is said that for the same load, the extension doubles if we double the length of wire! so there! 2x for one spring, therefore 4x for two springs :)

    i am saying that as the earth wire and live wire are connected at the same point, so a large current will flow through them. . Anyway forget this arguement, where i know i am wrong and please if someone could explain the mechanics, please do that why the case becomes live?

    I really have to Read this topic carefully!

    dunno, maybe due to short circuiting between live and earth wire?

    i have got so far that for one spring, the extension will be 2x, but cant understand why the same load can produce an extension of 4x in two springs?

    is there any sort of notes for this?? becoz i havent read this ever!

    a short circuit will occur, will it not, when current flows from live wre to earth wire? the large amount of heat produced will melt the insulation and cause a fire. that is my theory.

    but wont the high current flowing directly from live wire to earth wire cause a fire??

    i understand that the load is shared in the question, but in the second part, isnt the load shared by two springs?? so shouldnt it be 2x only?

    i told him, not showed him :P anyway, just posting some difficult MCQs, if someone could please explain: s09 Q30 http://www.xtremepapers.com/papers/CIE/Cambridge%20International%20O%20Level/Physics%20(5054)/5054_s09_qp_1.pdf w09 Q29...
