    Physics P3 (Practical) Notes and Tips

    hey i have 2 questions..first when we have like a pendulum question and we have to change d... it always says in the ms that d should be measured to the nearest mm what do they mean and second some sources of error relating to like question where u have to push a ball or an object is that its...

    U um ur 1st answer is for sure wrong.. Where in the world did amphere come from and ur 5th answer the answer to the resistance question was 12 not 40

    yeah i got around 49N i think.. and for the slit seperation i got something x 10^-4 not -3

    I got that wrong but apparently it was 180j 23m 90j and 90j

    I got 12 ohms

    Umm I don't know I don't think so since k depends on area of cross section and material the material is the same but diameters were not so I don't think k is the same.. I really don't know I got that whole question wrong :p

    1:.25 is another way of saying 4:1

    Oh u r talking about the stress ratio ya I got 1/4 but it's wrong when u substitute values u get 4/1

    But k isn't the same since diameters are different which effects the extension produced and thus shouldn't it be 1:2

    yay! how did u get 1:2

    no my teacher told me that there is ecf its just not in the ms.. and i dont rmr the marks exactly i think 3 for density and 4 for uncertainty and 1 for the final ans

    of course there will be ecf dw

    yea diameter was 22.1 mm and thickness i think was 2mm and the mass was 9.6g

    u use red light so wavelength increases thus fringe separation increases and brightness decreases.. not sure though

    oh well atleast one of us will get one mark for saying it decreases :P

    yea i got the absolute uncertainty as 825 as well.. then its 6.6% for sure coz i did it like 3 times
