Physics unit 3 IAL may/june 2018

In the official papers and in the official as books past paers all of them have taken t^2 as the dependent variable bro.

no wrong..T^2 IS THE DEPENDENT VARIABLE(Y AXIS)

But in the question (the plot the graph for 5 marks) it clearly stated that the graph should be lenght against t^2

0.169 was my gradient

OH MAYBE.if u did like that maybe they will give you marks.as you say.BUT u will never get a near value substituting the gradient to fimd g right.What was the answer for your G?

yep i guessed so and there shouldnt be a near answer for g (9.814) right?😜 like in range about 10.5 to 13 ??

I'll get the error carried forward marks

hmm.but if the paper has said so as u said maybe you will worth getting marks👍

How was the paper guys

Actually the paper was the easiest one except tge last 4 marks of calculation

3.3 is the gradient or 3.25

I guess there is gonna be a range because uk, it's a gradient

Yeah I mentioned everything except that. So yeah will lose 1 mark. And for chemistry I think the paper was a bit different. It should not be more than 35 out of 50 for an A grade.
I lost marks for the spectroscopy question and some parts of the organic question.

Chemistry paper was little bit a mind twister i think 32 will be a grade in chem and what was ur answer for 5 mark experiment

Oh wait I remember now i did x10^-2 and got 3.3333333333 etc as the gradient. And I found my G value to be 5.something

yep i got the gradient as same as you.so i made it 3 sig fig.(3.33) and the g value was 11.95

g shouldnt be that much LOWER.ORIGINAL g is 9.814Bro
