The most dangerous particles in polluted air are those with diameters less than 2.5 um because they can penetrate deeply into the lungs. Part A A 15-cm-tall closed container holds a sample of polluted air containing many spherical particles with a diameter of 2.5 μm and a mass of 1.3 x 10-14 kg. How long does it take for all of the particles to settle to the bottom of the container? Express your answer in minutes. D] ΑΣΦΑ At. Submit Previous Answers Request Answer ? min
