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 sure3- 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 
durin' da xam ma answer choice of C was pure luk 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!![/quote]
