what was the gradient ? and what did you people planned in q1?

 

[HamzaInam]

mine was F+1
and its value was 1.20..

 

[hanzlabia]

mine was F and its value was 1200

 

[HamzaInam]

what was ur wavelength ?

 

[Xenon]

gradient = F, value = 1190
for q1, plot a graph of q^2 against p and v = square root (0.5 x g x gradient)

 

[HamzaInam]

i think we had to convert the value to 10^-3....

 

[hanzlabia]

wavelength? wow xenon we are close what was your uncertainity
??

 

[breeze511]

i made a mistake in independent variable！how many marks i will lose？i misunderstood the question！my independant is v square！and dependant is right！

Q1. independnt P .. Dependent Q ... controlled .. Density of ball, initail speed of ball etc ...
> method.. diagram + explainatoin
> Analysis.. plot a graph of lgq against lgp^2 if satisfies equation .. a straight line is obtained..
> Safety .. keep a distance .. use sandbags
> improvemnts .. many

Q2. Gradient=F = 1.2x10^3 unc 0.1x10^3 ..... V/E = 11 ... and predicted value for V = 17.6 . uncertainities in table 0.6 to 0.2 ...

 

[utsav156]

the gardient was F damn i forgot to do 10^ 3 damn!!!

 

[hanzlabia]

my v/e was 10

 

[hanzlabia]

my v/e was 10

 

[samy]

for q1..
i wrote p is independent and q was dependent and stuff like dat..

for q2
gradient= F
gradient= (1.21 +-0.15) x 10^3
ummm v/e mayb 11 dun remember well....


how can gradient b F+1 ??? want 1 the y intercept??

 

[hanzlabia]

what was your uncertainity for v/e?

 

[samy]

em sry ijux cant remember it..may be like 1. something i dun remember!! :S

 

[HamzaInam]

i gat the same value of v/e mines was 10 uncertainity was like .2 ....my gradient was f+1....bt i think i messed it up a lot...
