a2m:
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

1)5 sce of the most power
2 i marked convection
3 the correct one was 2 n 4
4 the smae level B
5 bth dec
sweetest angel:
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!!
