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

    it is a BLOG, not some informative website,showing a wave drawn by hand, and by someone called "XINLEI"! I trust that blog as much as i trust ZARDARI! :P i have more exact answers in my books, thank you very much!

    Atp is not so much based on book! you have to do past papers.

    i think that CIE made a mistake when they asked that what is the movement of particle at X! so they will credit both upward and downward arrow!

    konsi book main dekh lia??? dobara jaa kai dekho. Main nai to jitni books main dekha, mujhe to kahin bhi particle at top pai koi arrow bana hua nazar nahin aaya! see if this answers ur query:

    no, we use water BATH when we have to keep temperature constant! it is basic biology, and becoz we do not have it in physics doesnt mean it doesnt exist in the world! extract below copied from s10_ms22. it isnt exactly according to our question, but it proves my point nevertheless : 11 (a)...

    post the link for the question paper! Anyway, please be a bit specific about which part? Q 12 EITHER, OR, part (i) (ii) (iii) (iv) or (v)? or which of these do you not understand?

    x can never be negative here!!! you see this is because when we take out of modulus, it will be positive always! multiplying x by 2 must therefore to be +ve, so x must be +ve

    if u are 100% sure about this then direction is downwards!

    ever heard of instantaneous rest? that is what normally happens to particles on top of crest or bottom of trough! though if the question was draw the direction where it will move next, or the direction where it had moved from, then it could have been down or up respectively!

    FYI, the particle at the crest or trough is at rest, there is no upward or downward movement! what he means, i think is using a water bath, which had been allowed in the marking scheme for the same purpose!

    it was one mark! and i dont exactly remember the question now! sorry :oops: it was resistor, and the correct choice was downward curve and straight line! option (C)

    I wrote use water bath and check temperature at regular intervals using thermocouple, this is what i once saw in marking scheme!
