How was physics paper 33

[Knight]

in Q2 was the relation true......
i got 15% difference in the two values.

 

[Knight]

my gradient was -.00125.......don't know the exact value.

 

[crazy123]

it wasnt true...

 

[crazy123]

every1s got a different value for gradient

 

[mujtabashahnawaz]

I didn't get the relation correct. I got 38%. And in graph, as 1/m increased h0-h/m decreased ><

 

[Knight]

the relation was true.........i hope.

 

[Knight]

i used 2 s.f for k......is it right.

 

[leosco1995]

My teacher told me that there is no specific answer to the relationship question. If the difference between your k values is < 20% and you wrote that there is no direct relationship, then you'll get full marks and vice versa. And I think the k values should have been given to 3 s.f.

 

[mujtabashahnawaz]

i used 2 s.f for k......is it right.

i used 4

 

[angelicsuccubus]

me too

I don't get it ... what was tough?

 

[angelicsuccubus]

the relation was true.........i hope.

yeh it was definitely true

 

[Knight]

I don't get it ... what was tough?

ploting the points and drawing a straight line.......my points were well scatered..

 

[Knight]

i used 4

i used 2 s.f for k as my values for diameter contained 2 s.f......

i think everyone did something wrong to the graph.. did your h decrease by a fairly constant value?

no, h didn't decraese constantly

 

[Knight]

what method was used to give the value of y-intercept....i used the eq. of straight line i.e y=mx+c

you're supposed to get that from the graph.. oh crap I have to take my earlier post off.

what post..

Did anyone experienced scattering of points?
And yes the relationship is definitely different for everyone. It is clearly stated in most Marking Schemes.!

i also have scatered points
