a2m:
that means i have the Power one and waves one wrong 100%
and 2 more questions may be wrong (Smoke and Barometer)
So say i have all 4 wrong and maybe 1 more which i am not aware of, do you think the curve would be higher than 35?? :'(
....:
Umm, for those who still don't believe that the barometer answer is B, please do check out Physics paper TWO for november 2008, question 6!

I cant remember the choises but you had to use Maxwell's right hand screw law

sweetest angel:
1- What was the answer for the most power question? (run up in 5sec or run forward and climb up in 8sec?)since time is inversly propotional 2 power...least time had greatest power But didn't the guy who ran and climbed do more work? Power = Work/Time???how do u knw work..distance was same and force remains unknown to us, only known variablw which we can judge frm is time!
2- What was the reason for the smoke above the fire? (Faster diffusion, Air Density, or Air Pressure) Why?since at faster diffusion rate the smoke particles diffuse from high concentration(near the fire) to low concentration (above the fire) and this is just a theory am not sure
3- Is it true that the longitudinal waves were 1,2 and 4?nope..just da drums (2) and (4)
4- What was the barometer answer? (Same level or the lower one?)i wrote lower What did ur teacher say?he said it was C...and gave the same xplanation i gave abt the thermometer hypothesis...am not that smart to come up with it on my own ;D durin' da xam ma answer choice of C was pure luk ;D
5- When the volume decreased in the syringe did both pressure and density decrease?since density is inversly propotional 2 volume...it decreased so did pressure!!
