    sure, its T^2*k / 4п^2 = m

    u rearrange the formula, easy things can seem hard at times

    thats good, u should retake as uve got nothing to loose. dhow the examiners that their questions r easy peasy.

    I got 72/90 in Phy 1`but i didnt bother to retake it cos i wanted to concentrate on the nxt modules. thinking about it now i should have. I didnt even think i will get an A in phy 1 cos it took me sometime to get my head round some simple stuff.
