    Biology; Chemistry; Physics: Post your doubts here!

    oh great!! plz remembr to tag me in the post too wen u post it bcuz i'm having the same problem w/ transformation matries. i can't seem to learn them so i have to work them out for every question and its HECTIC to say the least :mad: :|

    XCUSE ME!! he electrons of metals are NOT in the orbits. they are delocalised!! that's the whole point of the metals being good conductors because they have a SEA OF ELECtRONS that helps to carry the heat/electricity! o.O

    Another confusion everyone *heads up* :P When we label the axes on a graph, if one of the axes is supposed to be 'nuber of sth.' lets say "number of bounces" and is represented as "N" . how do we write it?? i mean we can't write the unit for it but we are supposed to label the graph like...

    Excuse my interruption but i wanna pop ur bubble ryt here cuz i replied to the fact that the dude said that heat IS NOT TRNASFERED IN METALS DUE TO ELECTRONS which is WRONG!! [and i don't even care to display my resources here. my words are enough] :P there was no talk of conduction or...

    u can minimise it by using a container with shiny, white covering as black, dull surfaces are best absorbers and emitters of heat. :)

    Biology; Chemistry; Physics: Post your doubts here!

    WAT??? heat IS transferred due to the movement of the free elecrons as they move and transfer their kinetic energy to the next electron and so on.... and if what u say is true and it is NOT b/c of electrons then explain y heat is only transfered (best) by metals [which have free electrons] and...

    *deep breaths* dude that is EXACTLY what i asked that WHY are SMALLER compasses more sensitive to magnetic fields! anywys i got the answers but another one wud again go apprecited :)

    yh actually that was my question that WHY can a SMALLER magnet detect them and not a bigger one!!

    heyy guys can anyone explain this answer: Q. what is the advantage of using a smaller compass? A. It can be used to allign the weak magnetic fields o.O :confused:

    Biology; Chemistry; Physics: Post your doubts here!

    NO!!! bhaii!! responsiveness and sensitivity are two different properties!! although the difference is minimal but still they are different. Sensitivity: the length mercury moves after a change Responsiveness: how quickly the liquid moves after detecting a change. c they are different.

    howw?? it makes it more responsive. besides this is not what i said. i got these questions off the internet somewhere long tym ago so idk. if u think there is something wrong and u r ABSOLUTELY SURE ABT IT then post it here. :)

    is the answer 0.2mol/dm3 for the first one??

    Biology; Chemistry; Physics: Post your doubts here!

    yeah but they didn't tell us the amount of water so how do we know that there is lesser water in there so lesser H+ ions than Na+ ions will b formed. sorry for the nagging ... i just can't stop until i get it al cleared :P

    physics paper 1,2 ........can we discuus da papper nw?

    no no not that 1!! i am talking about the one in which there was a SINGLE electron shown and a grey area of magnetic field and we had to determine the direction of the electron beam. the one u r talking about is about 2 current carrying wires.

    what is meant by FIDUCIAL AID?? it is in relation to physics atp. in some notes my sir gave me. i looked it up in the dictionary for fiducial and it said: "(esp. of a point or line) assumed as a fixed or basis for comparison. please can anyone elaborate on it?? it is mostly used in ray diagrams...
