Solve the given questions:

Question: Calculate the time required for the radius of a spherical snowflake to increase from 1 mm to 1.5 cm if it grows by aggregation as it falls through a cloud of small ice crystals present in an amount 1.5 g/m³. Assume the collection efficiency is 95%, the density of the snowflake is 10% of the density of liquid water, and that the difference in the fall speeds of the snowflake and the ice crystals is constant and equal to 2 m/s.

I'm having struggle with this question. Please, show me the process of solution. Thanks!
