Ur right...thr's no relationship between cross-sectional area and the height of the mercury....
The formula for Pressure in Fluids is = hdg...Height gravity and gravity.....since gravity is the same and so is the density and so is atmospheric pressure height wont change

100% Correct.....
Guys what did you write for the fuse question and the other one regarding the placement of a fuse or a circuit breaker?
For fuse I chose 1A ... not so sure and for the other question I chose the position of both the fuse and the circuit breaker at X (live wire)... am I correct ???
The echo for the click was the ZY position (not sure of the abbriviations) but it was the one with the short distant wall.
For the copper&wood question... I didn't choose copper at all because it's a good conductor of heat and the whole thing will be really hot .. so it was obviously the other end of the wood?

for the echo thing im 100% sure it was zy because it was a repeated question i saw the answer in the marking scheme

Yes it was repeated actually :P , I've done 16 past papers 2 days before the exam lool. Well, I guess my doubts are done... however I just wanted to make sure of a few other things.
First question... was the answer 50m/s?
Third.... 0.764m ?
And the average power... was it the one where the person runs up the slide thing ?

i feel barometer is b bcz cross section area doesnt affect d pressure
d fuse n live wire thingy was x n x i guess mostly correct
n ya wht was tht magnet n tht p q
i wrote c p=south n q=north n ya ne more doubts plz put up asap

i dont remember the fuse...the barometer is correct..its all correct im not sure about the first one though..wat was the magnetic effect *the compass*??????direction???
