Physic 34

[Mattman]

How was it?
gradient=2.98
a=2.98V
b=931.0ohm
% uncertainty of k is 13.3%
relatively low % suggests relation is supported, but more readings must be taken

 

[Anonymous stranger]

Yup all my values match yours but my % was 19% and so relation ship was not supported as it is greater than 10%

 

[ibadsiddiqi]

damn my b was 744N..:-/..and my percentage uncertainty was 22%

 

[Anonymous stranger]

Values of D were 0.73 mm and 0.98 mm right??

 

[Mattman]

eh? we have the same wires?
my ds were o.75 and 0.88

 

[Anonymous stranger]

Y intercept 3.10
Gradient 2.86
Value of A was 2.86 V
Value of B was 0.93 K ohms
D was 0.73 and 0.98
Percentage came as 19% thus it is not related
Sources or error were:
1 two readings not enuf....
2 block holding the wire is pushed away when the pin is hit so we need to hold it...
3 block doesnot move freely as it rubs with the A4 paper on its back...
4 pointer moves too fast so use a slow motion camera...

No even people at the same centers were getting little deviations frm each others values
Guess we don't have the same wires

 

[Mattman]

Ah k.
intercept for me is 3.2mA
2 readings not enuf
parallex error when reading the degrees
zero error of micrometer
high friction on the pin by the pendulum makes it so that the angle of oscillation is less/or the hole is uneven

 

[ibadsiddiqi]

Diameters for me for 0.77 and 0.98
i wrote 2 reading not enough
Parallex error when recording the degrees
Difficulty in measuring the max angle because of the fast movement of the pendulum
the pendulum may not be vertical

guys i made a blunder........My readings for current are wrong.....so will i get marks for drawing a graph from wrong values?

how can they be wrong? ;p

 

[Natashakhan]

wat will b the gt?

 

[Saad (سعد)]

The paper was awesome ma sha' Allah.

Pretty easy.

 

[Mattman]

as usual low 30s probably.

If they were wrong, u wil still get the marks provided u drew it coorect

 

[ibadsiddiqi]

yea its not going to be more that

 

[Henry930821]

Omgg i forgot to convert the units of the gradient from AΩ to V how???
I in deep troubleee? Would i lose all my marks?

 

[littlecloud11]

Paper 3 totally made up for paper paper 2.
just 1 hour for this was more than enough.

Whoops... I did the same thing... I wrote AΩ and forgot that V = IR.

... But I don't think they'll mind. I mean, its not wrong... is it?

Well yeah theoretically they are equivalent.. My lecturer said it should be acceptable too since Aohm also equals to V. Just hope they wont be so particular about it..
