Practical physics questions - Pressure & Uncertainty

[QUOTE="charlottexo, post: 4318711, member: 468227"] Guys about that first problem to do with the pressure. I think I may have a solution and I was wondering if you could check it please? Modify the apparatus to include a pressure gauge and see how far above normal atmospheric pressure it reads with no mass. Find the cross sectional area of the syringe and multiply this by how far above the reading was (in pascals of course). This way, you can see how much extra force is being applied relative to normal atmospheric pressure by this new atmosphere. Then, any readings you take, you subtract this value of force to take into account this excess atmospheric pressure. I had a long hard think about it, could someone please check that this is right and answer my uncertainty question? Thank you :) [/QUOTE]
