it was so good.. what was ur answer for the g in the last question? i got the gradient as 3.33 and the value for g as 12

11.84 ryt?
Coz i got the same value for gradient.
Did u draw the graph through the origin?
I got my gradient as 3.24 and the g value as 12.18

yeah, u?
In the viscosity experiment - I forgot to write that "the ball reaches terminal velocity at a certain point". Other than that, i wrote everything about how to measure the radius, height and time for velocity etc.
What do you guys think how many marks I'm gonna lose for that particular statement? 1 or max 2?

Maybe 1 but only if you mentioned how to find it by measuring the distance and time.
Will 33/40 be an A grade?
Any predictions for grade boundaries of chemistry unit 3

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.

What about physics?

No.... did they ask us to draw through the origin??
I guess then its wrong !

They even asked us why the graph would be a straight line passing thru the origin in one part. It was pretty obvious

if you start the graph with 20( x axis) yhe graph isnt go through origin.but if you start with 5 and plot thegraph.when u extend the plotted points backwards it goes through origin.i checked both of that in the exam

i guess i am right😂😂😂😂😂
Is the graph supposed to be l against t^2 or . t^2 against l


I did l against t^2 with proof of S=1/2 at^2 (Y=mx)

yes t^2
Original post by barbiedoll98
yes t^2


I mean t^2 on the x axis and length (x10^-2) on the y axis
Because for the 5 mark question it stated that it should plot a graph of length *against* t^2

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