How was the paper guys?

 

[Muhammad Haris Ghani]

The paper was good mashallah

what was the gradient you got?

 

[22shimmer22girly]

i got a positive gradient and you ??? hey guys if you got a negative gradient then what were your values for A and B???
For A, it was the same as my positive gradient and B was y-intercept.

i got a negative gradient.

 

[Muhammad Haris Ghani]

I also got negative gradient which was -0.132 and intercept was 8.227

That sounds very wrong. Its definitely a negative gradient. You'll probably lose a lot of marks for graph and table of values. Did you plot length on x axis and the A-B/r on y axis?

 

[Muhammad Haris Ghani]

i plot x on axis and a-b/c on y axis offcouse how can this be wrong

 

[PrincessLuna]

I didn't quote you.

 

[Muhammad Haris Ghani]

ohh sorry I am mistaken anywhy can you tell me your values

 

[Muhammad Haris Ghani]

i got a negative gradient.

what was your gradient value

 

[PrincessLuna]

ohh sorry I am mistaken anywhy can you tell me your values

Grad -0.09 , intercept I forgot ... but am not concerned about qu1 as 5 points were on line while 1 point was slightly away from line.


The second qu am not too sure.

 

[Muhammad Haris Ghani]

what was the gradient you got?

what were your angles

yes one point was out of line what about ur angles

 

[PrincessLuna]

what were your angles

Everyone got different angles as it depends on force you pull it with. My teachers says cie should accept any angles as long aa procedure is logical.

 

[Muhammad Haris Ghani]

yes one point was out of line what about ur angles

so this means that both of our value is in range of almost 0.1 which may be right

was your k was supported or not

 

[PrincessLuna]

Irrespective of what the marking schemes say CIE also understands that this may vary slightly from centre to centre because of equipment difference. If many others at your centre got similar results it will be accepted.

 

[Muhammad Haris Ghani]

was your k was supported or not

what was ur pecentage uncertainity

 

[PrincessLuna]

was your k was supported or not

Mine was but for a lot of others it was not, what about you?
