bdw first question ans. was 50m/s since they gave us distance 'n time...average was 2 confuse only
'n i did revise da ppr wid ma teacher so am  pretty sure
the barometer is c...sme pressure ya buh since its wider the mercury takes less height!!its sme application as thermometers tube!! (actually  i tink its the thermometer theory they were actually testin' wid this question!)

I have a couple of Questions about the paper..
1- What was the answer for the most power question? (run up in 5sec or run forward and climb up in 8sec?)
2- What was the reason for the smoke above the fire? (Faster diffusion, Air Density, or Air Pressure)
3- Is it true that the longitudinal waves were 1,2 and 4?
4- What was the barometer answer? (Same level or the lower one?)
5- When the volume decreased in the syringe did both pressure and density decrease?

My answers were:
1- The 8 sec Choice
2- The Air Density Choice
3- The 2 and 3 ( I know I am wrong)
4- The Same Level Choice
5- Both Decreased

2 i marked convection
3 the correct one was 2 n 4
4 the smae level B

these were ma answers
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
2- What was the reason for the smoke above the fire? (Faster diffusion, Air Density, or Air Pressure)
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
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!!

i had sme answers ;D/
barometer question is repeated but i am studying chem at the moment so i cant look which year....something in the 1995 or before  :-\

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???
2- What was the reason for the smoke above the fire? (Faster diffusion, Air Density, or Air Pressure) Why?
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?
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!!
