Well my for the carboard, i drew the weight directly at the centre with a small arrow pointing downwards. Then it said show the c.o.g with a point C so i just drew it directly below the arrow since i couldnt draw it at the same place as the weight :S i really dont know, in theory both the c.o.g and the weight should be at the same point.. oh well i guess i lost a mark
yeah i got the same definition :) and yes there was a questio asking weather the wave experienced power loss. and i said that yea it did becoz the amplitude was decreasing constantly.
for the beta i rote it is negative so wil get attracted to the nucleus. and its light so will travel extremely fast making it hard to be detected (not sure.. what do u think)
For my combined resistance i got 1000 ohms but based on what people told me im wrong and the answer is actually 965 or something around there. and if you got that combined resistance wrong then you get the question with the temperature wrong. So i lost like 4 marks there already :( plus i didnt know what to write for why the 10 voltmeter would not be used :(
overall i think i lost like 12-13 marks. do you think that will get me an A for this paper? I dont think i will because this paper was considerably easy if you think about it :(

The C.O.G is only a point. The weight acts downwards from the point. So your arrow representing weight should start from C.O.G itself.

Yupz...............now I remember. I also said amplitude was decreasing in Fig 5.2. :D

Almost same answer as mine. I guess it should be right. ;)

Hmm..............am not sure about it myself. But in the exams I was pretty sure I did the number correctly. However my friends obtained other answers. :(

I lost marks due to silly mistakes too. We never know if the threshold will be decreasing or not. That will depend on the performance of the overall students. ;)

That's good ;)
I can't say exactly for me.
Do you mind to compare your answers?
