How did u guyz do in phys p1 ?

[sloe]

I can only remember choosing the ans which was on the top left of the graph (4 protons, 4 neutrons).

and i remember chosing B

[mr.incredible]

The lithium question was confusing but in the end i chose A .

What about the following questions:
1. The force extension graph where the spring constant was required
2. The force distance graph of the electric field where there was located a positive charge
3. The change of state of ice to water
4. The electric field question where there was a positive charge located in a circle
5. The uncertainty of the density of something

0.2
constant straight line
decrease-increase
they say its 0 but i put C E * pie*r/2
0.6

0.6

For the spring constant, I don't remember 0.2 as a choice !!
Why do the spacings decrease when ice becomes water ??
Are you sure about the uncertainty ? I chose 0.5.

ans for 3 is B
ans for 4 is A ( which is o even i did what 'spy' did i chose C)
ans for 5 is B
would u plz specify the first 2 question (i have got a poor memory)

1. A force (N) against Extension (mm) graph and it was a straight line which had a negative gradient and the spring constant was required and the answer i chose was 500 Nm^-1.
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.

[[Spy]]

no im sure for the constant its 0.2 it was simply y2-y1/x2-x1 gradient and i tried it for many points it always worked out as 0.2

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

[vserian]

I badly did that paper
i felt very sad i even cried a little bit because i did all the past papers and did well in them, but in this paper i did a lot of mistakes!!!

Did you convert the mm into m ?

Can you tell me the steps you did for the uncertainty. I can tell you mine. I subtracted maximum mass of of beaker + liquid from minimum mass of empty beaker and divided minimum volume of liquid by this answer. Do you remember the values and uncertainty of each ??

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

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 ) but what i said was right

Well Sabrina, I have to say that you are just putting down the fire inside me   . 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

[piggydiggy]

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...
