even if either one of our answers is wrong we can still get one mark for writing the formula correctly i believe...I got it using the formula, P=I2R. 0.75x0.75x 8.=4.5 W.

everything become negatively charged...even the positive section becomes negatively chargedWhat was the answer for the charge on the sphere after it was earthed?
yup!Electrons flow from the Earth towards the metal sphere, not the other way around. =)
u didnt do da ppr??THE PAPER WAS VERY FUNNY SO I SLEPT.
THE TEACHERS WERE ANGRY. IM PRETTY SURE THAT TEACHERS EVEN DIDNT KNOW THE ANSWERS.
THEN JOHN CENA CAME WITH A MIKE TO ME AND SAID THAT DO YOU SMELL WHAT THE ROCK IS COOKING. I ANSWERED THAT I AM DOING EXAM AND TO COME BACK LATER. WHEN I WOKE UP 3 TEACHERS WERE STARING ON ME AND THE INVIGILATOR SAID THAT 1 MINUTE IS LEFT. SO I THOUGHT WHAT THE HELL WILL I DO IN 1 MINUTE, SO I SLEPT AGAIN. THIS TIME I HAD DREAM OF OSAMA BINLADEN TELLING ME HE HIS KHAN AND HE IS NOT A TERRORRIST.ANYWAY INSHALLAH EVERYONE WILL GET "A" STAR (INSHALLAH). JUST STUDY WELL FOR PAPER6, I AM ABOUT TO SLEEP NOW BECAUSE 3 DAYS ARE LEFT.

For me it was alright .......But some questions were really confusing like finding the mass of the ice used. Bit time was not at all a problem with me. I finished 15 mins before the exam.o my god i cant believe how hard that paper was. The paper was so twisted and hard that i actually ran out of time. I wasn't the only one.
I left a few questions to answer later on and when i finished my last question i ran out of time and never got time to attempt those questions. i left about 20 marks unattended.
Solving past papers didn't help at all. who else has finished this paper? how did you think the paper went, for me it went terrible.
i finished 25 minutes b4 da xam was supposed 2 b overFor me it was alright .......but some questions were really confusing like finding the mass of the ice used. Bit time was not at all a problem with me. i finished 11 mins before the exam.
that'sprobably correct too, i faintly remember seeing that as an answer.sorry man, 4.5 watts. :/ I took the time as one second.
expecting 65 to be lowest.how many marks u expecting???
70??
yea i know !!! :'(unlucky i was even harder
it was a glass flaskNot sure if this was brought up, but whatever.
In variant 1, there was a question about a bulb containing water at room temperature with a glass tube as the only opening upwards.
It was placed into warm water. The level of water in the glass tube decreased slightly then increased.
(a)Suggest why:
(i)the water level first fell
(ii)the water level then rose
(iii)the rise was greater than the fall
Any ideas about the answer? I'd really appreciate some help. The second one is pretty easy, but I'm not so sure about the first and third
