    physics paper 33

    SO if its like t=(t2-t1), then uncertainty in t is (0.1 / 2)/t , assuming uncertianty for a single reading of time is 0.1 seconds?

    Kay. And can you plz explain what this means? "When repeated readings have been done then it is expected that the uncertainty in the measured quantity will be half the range"

    Ohkayy...by "at the end" you mean when we write the answer in the ___ at the end of each part like ii) or iv) ? And what about in tables, use SI for those too?

    physics paper 33

    In Q1 sometimes they ask you to measure the length of something, and the answer space its like:" ___ cm" or " ___ mm". Unit is already given in cm or mm but those are not the standard unit, m is, so later on when they ask us to take readings, do we take them in cm, mm, or in m?

    AS Physics 33...Units?

    For example in Q1 sometimes they ask you to measure the length of something, and the answer space its like:" ___ cm" or " ___ mm". cm or mm is not the standard unit used, m is, so later on when they ask us to take readings, do we take them in cm, mm, or in m?

    Ok, thanks.

    AS Physics 33...repeated readings?

    In Q1, where we have to get six values, do we take 2 readings of y for each x and write the average reading of y in the table? Or just one reading will do? If 2, how to we show that in the table? Like, in the column for y we write (y1 + y2) / 2 = Y ?
