    thanks. actually most questions get repeated. the type of question is always 39/40 repeated. only one or two new questions come each year. with practice there is no reason why YOU can't get 39/40

    x=dλ/a in case 1, 1E-3=d600E-9 / a so d=1667a in case 2: 3E-3=(d+2)*600E-9 / a a=(d+2)*600E-9 / 3E-3 a= (1667a + 2)2E-4 a-0.333a=4E-4 a=4E-4 / 0.667 =6E-4m=0.6mm this was the only way it came in my mind. maybe ZaqZainab or someone else can tell a shorter way. if no shortway comes into your...

    3: simple. the speed must have units m/s in (a) √(gλ)=(m²/s²)^½ = m/s no need to check rest of them :P 7: O level vectors: x=v-u v-u = at so x=at 20: All i can do is visualise which parts are bending in what way. X and Y are being stretched but Z is being pressed/compressed. X and Y experience...

    no need to complicate the things. if you don't know anything you atleast know you need the enthalpy change which produces PbO but combustion of lead can give any lead oxide. we don't know which one but it can be PbO, PbO2 or whatever.

    question number 1: there is limited amount of nitrogen, hydrogen and ammonia. at equilibrium N2 and H2 react to form NH3 and the reverse also happens. if you take away NH3 the backward reaction stops. so the concentration of reactants N2 and H2 will decrease. so the rate of forward reaction will...
