When you stifle a sneeze, you can damage delicate tissues because the pressure of the air that is not allowed to escape may rise by up to 45 kPa. If this extra pressure acts on the inside of your 8.4-mm-diameter eardrum, what is the outward force

The outward force is 5934.6N.

Explanation: Pressure is force per area. As the eardrum is a circular organ and has 4.2·m of radius, the area of the organ will be:

Area = π·r²

Area = 3.14·(4.2.)²

Area = 13.2·m²

To calculate force:

P = F/A

F = P·A

F = 45.·13.2·

F = 5934.6N

The outward force is F=5934.6N.

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.
