    thank God some1 has brains :)

    HOW WAS PHYSICS PAPER 2 AS!!!!!!!!!!!

    umm do u know wat the antinode was on that wave? a wave of intensity nd distance? the highest points( i think it was 2 not sure) while the nodes where the ones on the x axis. as intensity is maximum during an antinode and zero during a node. nd the distance between two of them was 0. 34...

    and u r saying a PART of a wave cant be its wavelength even if the part shows three nodes?

    in a part of the wave distance between 3 nodes is the wavelength. even if u took distance between two nodes u had to multiply it by 2

    SAT II (June 2nd)

    Plz Barrons is a totally irrelevant book and spark notes totally misguide you. Princeton is in ever way better than barrons. Prepare from Princeton. Then do practice tests of Barrons and princeton. Except Biology. When i took my SAT Bio the questions asked wre neither fromm princeton nor from...

    read the previous post. i apologized. my concepts r clear as its obvious by my answer of 500hz. it was a simple typing mistake

    yeah sorry 0.68m was the distance between 3 nodes hence lambda nd so 500hz

    mass-energy is conserved not mass. mass is converted to energy acrdng to E=mc square

    distance between two nodes IS lambda not lamba into 2

    Aga khan entry test 2012

    Not today people. I called them a day before yesterday and they said that on the 31st we(the admission office) will get the results from the examiners and then after that however long it takes to reach you.

    does any1 remember P.E? did we have to find the change in P.E between A and B or aftr it has bounced off till B?

    current was i think 1.1*10^-3. chnge in ke was 1.8

    yeah not equal energy loss occurs

    umm wat was the question?

    HOW WAS PHYSICS PAPER 2 AS!!!!!!!!!!!

    we have to take it twice as antinode is above the tube

    HOW WAS PHYSICS PAPER 2 AS!!!!!!!!!!!

    100% sure i am ryt. distance between two node gives wavelength. nodes occurs wen amplitude is zro and so intensity is also zero. the distance was 0.68 :)

    wat about it?
