    use the young's modulus equation.. after simpificaiton you should get Y=FL/Ax, open A it will be pi. D^2/4, make x subject, get x= (4FL)/(pi.D^2Y) do the same for the next one, but instead of L use 3L and instead of A being that, it will be pi.D^2 after cancleing out the 4s, make extention...

    woke done= kinetic energy, =0.5 x m x v^2, 0.5 x 800x1000 x 50^2 = 1x10^9 J ;)

    g from the def of atomic number its supposed to be the number of protons, if an electon is removed, the only change that happens is there should be a charge, there should be no net change in atomic number! dafoof! oh gosh i dont even know

    wait a minute.. the bottom number indicates the number of protons not electrons.. i dont get it, electrons are never counted :S the number of protons remain the same, the mass number remain the same.. there is not answer to that :O am i getting my concept wrong :S D:

    i can do that! use from pressure =foce/ area, you get force=pressure x area also force=ma, so equate the two you get ma= pa, a=(pressure x area)/mass, you can get the answer ;)
