How did u guyz do in phys p1 ?

2. A force against distance graph where the positive charge moved from the negative plate to the positive plate.
Are you sure of number 3 ?? I think that both the spacing and density should increase. Does anybody agree with me ?
I chose +/- 0.5 for the uncertainty and i heard from fellow students that it should be +/- 0.6.

oh ya now i remember the 1 ans is 500Nm^-1
2 i think the ans was the one with the straight line staitionay sort of
i m sure abt the density uncertanity it was .5

and for the density yeah im sure cause if you decrease the spacing then you decrease volume which is inversely proportional to the density and therefore density increases, so one is decrease and the other is increase
and yep uncertainty was surely 0.6 :D

Dear spy
i have checked the paper with my sir after the the xam. the answer is not .2. n the density is also no .6
sorry to dissapoint u but this is the truth( just kidding :D) but what i said was right

Well Sabrina, I have to say that you are just putting down the fire inside me :D . I hope that the uncertainty density and the spring constant choices are correct :) .
What about the question of the wave that will experience significant diffraction. I remember the choices were Infrared, Radio waves, Ultraviolet and Microwaves. What was your answer ?
Also that one about the energy efficiency of the car going up the slope, what was you choice ?

i m sorry but really whatever i m saying i cross checked my sir.
for the wave i think it was ultravoilent ( do u remember the frequency or the wavelenght which was given if yes then i can give the exact answer right now)
for the car going up was D

wot wot wott? the best paper.. omoo, its like my worse paper.. :(
i dunno how to count the energy" thingy.. and need to read the procedure like 20 minutes..
the no.2 was okay but the 1st one is like wot thee...
