the strange thing is i did perfectly well in paper 3 and 6
i always screw up in paper 1

Yup, i got bout 5 wrong now....

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?

that's correct, n fuse and circuit breaker both lies in the live wire,
and dude is it really ZY cuz I want the true answer

Fuse was 1A as it was the fuse directly above tha amount of current required for appliance (bulb) to work to its maximum potential.
Fuse and circuit breaker i put fuse on live wire but circuit breaker in the circuit so in the other position, not sure whether its right though.
Echo was ZY :P it was pastpaper qn and i got it wrong so i knew the right answer in exam
i got the copper wood i got same answer which was A, the wood end of the tube thing

For the one where they were running I assumed the people who were running across the beach and up the ladder ran a further distance than the people running directly up the slope so Work Done = Force x Distance
That's why I chose the person who ran across the beach and up the ladder while taking less time therefore more power.
girl_92:
it was the person who runs up the slip way with the least tym if u wanna chk try this out take any values for the beach suppose 6 n for the height of the ladder suppose 2 den calculate the slipway's length using pythagoras den use the formula power= energy/time since they already mentioned their weights are same that means the forces are equal take a value for the force calculate workdone= energy
u will get ur answers

Hello, yes i'm pretty sure that it was the small distant wall which was ZY I think, I did that in a past paper before the exam by a day. The question was still fresh in my head.
