Estimate the radius (mm) of a spherical particle of density 1789 kg/m³ that reaches a distance of 683 km if it was ejected at a height 1200 meters from Busay to a final height 16.93 km into the atmosphere the mean wind speed through the atmospheric layer is 26.84 m/s. Viscosity and density of air are 1.923 x 10-5 kg/m-s and 1.301 kg/m³, respectively. Express your final answer in 4 decimal places.
