    Also, there was one question asking for how should the systematic errors of height and time to vary to find gravitational acceleration, right? Did they ask for the value greater than gravitational acceleration or just exact?

    Well, i answered that as well, but did they say it delflected by large angle?. The uncertainty that i answered was 6.7 but i think the answer is 4

    For physics pratical...

    For the question 1, we carry out the experiment one time for the first part of the question, right? Then, if they ask us to repeat the experiments until we have six sets of reading, is the six sets including the first reading we have carried out in the beginning or not?

    Yo, guys... For the resistance, did they state in the question for giving the answer to 2 sf? Because most of people are saying that it's 4500.. I wrote 4510..

    How did the physics 22 paper go?

    However, I got 4510 for resistance..., no difference is it?
