Rockerette

you did have to do didnt you??
to get the time for 1 oscillation??

please tell me you did.

im prettt sure, but sure, im just a girl, so dont trust me

yeah i read the kind of introduction thingy at the top of the first question after and it said the time t for 25 osicalltions was recorded.... i managed a straight line graph though aswell

Rockerette

yeah but the X axis will still be proportioned, forming a straight line through the origin, whethere or not you divided them all by 25..

I thought it was pretty good. The experiments were reasonable. Overall a grand paper.

You have to divide by twenty five indeed. I did not divide the given angle by two but when I was looking at it I thought that's what they meant. Then just assumed they couldn't and said sin41.5. oh well! I loose about 5 marks.

You have to divide by 25.
Then you plot either t and root(l) or t(squared) and l
You had to divide the angle by 2
you got 2(lambda)=dsin20.3
For d you had to invert it[1/300] and multiply it by ten to the power of -3(to get the distance between the slits in meters

I said the string was inextinsible because you want it to oscillate in one plane only; or something to that effect

Go to maddox.xmission.com to forget about that exam. Read the one at the end about childrens artwork

F!uck.




gah.

stOOpid me, i never divided the angle either.

bollocks.

in q6, What were the forces acting on the ball?

in q8, the isotope of helium is 3/2HE right?

in q12a,the pressur at the bottom of the lake is three times 1.01x10^5?

and finally, Q12d, how do you calculate the energy of the electron when it passes thru 50Kv?

i think i did ok, but i dont want to hedge my bets.

ye you had to divide by 25 for one oscillation and then square t

i ****ed up in the Q1 cos i thought it was the formula g=2s/t squared, so i squared t and doubled s. shoit

thats what i did too!
do you not have to do it???

Kovik

I thought it was relatively okay until I realised how I ****ed up the question about the lenses. That was forty marks gone right there.

Rawr. I was looking for a B2, not sure if I'll make it now.

I said that pions are produced because the photons experience pair production forming quarks and their antiquarks. As mesons, pions are made of a quark and an antiquark.

what a ****in paper...im over the moon...i did every question except for 9 and 11,the electricity ones...so much easier than i expected it to be
