1. The problem statement, all variables and given/known data When you stiffle a sneeze, you can damage delicate tissues because the pressure of the air that is not allowed to escape can raise up to 45kpa, if this extra pressure acts on the inner parts of your 0.0084 meter diameter of your eardrum, what is the outward force? 2. Relevant equations work= Pressure * Volume Force= work/ circumference pv=nRT 3. The attempt at a solution i have no idea where to start, i know that pressure is related to work by volume but i do not have any measurements for volume, i know i can get volume but i do not know temperature or amount of moles, i know i can said p1v1=p2v2 but i do not know the original pressure or original volume to make that assumption. I just need to know what to look at to start the problem Thanks!!!!
