IGCSE Physics Paper 6 doubt

Scroll to see replies

There was a question on the 2nd side of the 1st page saying where z would go once the weight was moved (it was hard to see and only 1 mark)

Damn must have missed it! And yeah when resistance is constant, voltage increases with current.

Yeah. don't worry about that - many people got it wrong including myself i believe

for the last page, what did you put as the range of masses and the number of readings?

What did you put for the last question on the first page where you put your measured values into the formula and then compared to what the guy said it should be? I got 1.11N I think

at the right of the pivot, just a little... I even calculated it >.<
How did you do the one that gave you the graph and you had to say the length of I dont remember what?The one with strange units

I said change the current by using a variable resistor

I put 10 masses from 0.25kg to 3.75kg increasing by 0.25kg each time

you had to find t, and the graph was t/squared, so you had to extrapolate from 4, which gave you 0.98 / 1.0

Its only a mark and it only counts like 20% so dont worry, the important one is paper 3! T.T

Do you reckon you'd get a 2/3 marks for correct working but missing the squared bit?

Also do we get our papers back once marked?

Finally what did you guys get for the bit on the first page where you put your measurements into the formula and multiplied by 10?
