    I DID GET 3.3!!!! but i dont know why. should i always just work out the area to be on the safe side?

    Why didnt you assume the whole thing as a triangle? and also why didnt you use 0.5 * k * x^2

    yeah but it didnt make sense... the numbr of neutrons on both sides is the same.. so how can u say they are not conserved

    but the number of neutrons are balanced on each side!!! and so is the nucleon number....

    AS Physics P1 MCQs Preparation Thread.

    Thats not true, in Beta decay, often one side will have one more proton than the other due to the nature of the decay (a proton and electron together) so charge/proton cant be, thus if the proton number isnt conserved neither can be the nucleon number. Also neutron number then isnt conserved...

    Actually, they asked for the potential energy lost by the WATER, which i guess includes the whole system, i think it doesnt matter what the actual volume of the water is, it just depends on the height and mass due to the equation thus you dont multiply by two. Btw leosco1995, can you please...

    why dont you multiply by two for question 15? ... i mean you have two containers each with mgh/4 , thus that wud leave u with mgh/2 ??? also Q18) why would you include the decrease of a distance on the LHS, like can you explain it?
