it was the 4 ohm resistor
the question of the power of the lamps, what was the answer ?

the question of the power of the lamps, what was the answer ?
i made it wrong i said 12 ohms because higher resistance higher voltage and higher voltage higher power as P=VI as v increase p increase, how many marks i will lose all of it?4 ohms has higher power
not really sure dude. cos u gave the ans as 12+ ur explaination is completely wrong.... srry mani made it wrong i said 12 ohms because higher resistance higher voltage and higher voltage higher power as P=VI as v increase p increase, how many marks i will lose all of it?
y mean i will lose all of the mark?not really sure dude. cos u gave the ans as 12+ ur explaination is completely wrong.... srry man
follow the link and read the manometer part. You will see why we have to subtract AND NOT ADD.Yes , i think that's exactly what i did, you have to add atmospheric pressure and the pressure you got not subtract them.
y mean i will lose all of the mark?
i added them too!The first link mentions in Case 2 that was our case "Thus, in this case the pressure of the gas that is trapped in the closed end of the tube is greater than atmospheric pressure by the amount of pressure exerted by the column of liquid of height h." So the pressure is greater than the atmospheric pressure which means addition must occur not subtraction. In the second link, you'll notice that they mentioned p(gas) = p(atm) + p(h2) which has the exact same diagram as ours. This diagram with open tube is the same diagram as the one in Paper 31. Also, the height which was 250mm was high too. So, overall addition must occur and I'm sure of it and you proved it with those links.
man the atmospheric pressure was higher than the gas iam sureThe first link mentions in Case 2 that was our case "Thus, in this case the pressure of the gas that is trapped in the closed end of the tube is greater than atmospheric pressure by the amount of pressure exerted by the column of liquid of height h."

I am completely sure that the mercury was the other way round. The gas pressure was less than atmospheric pressure because it pushed the mercury less, thus making the level go the other way round. So we have to subtract 100000Pa- 34000Pa so we get 66000Pa, making it lower than atmospheric pressure.
Really? I thought that it carried three marks, which made me worried a lot. Thanks for informing me XPstop talking about the atm question (addition or subtraction) !!!!!!!!!!
it carries 1 mark only
instead of arguing about this 1 mark
discuss about different questions which carry 2-3 marks
anyway i added them
vry easy..........Yeah... it was so easy....
32 was hard :')such an easy paper evn a baby cn do it....
