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
