A sphere of radius 50 mm and mass 1 kg falling vertically through air density 1.2 kg m attains a steady velocity of 11.0 m sr', If the above equation is applied to its fall, what is the value of k in this case?

This is a form of winter precipitation. it is frozen precipitation falling as ice pellets. snowflakes melt into raindrops as they pass through a thin layer of warmer air. the raindrops then refreeze into particles of ice when they fall into a layer of sub-freezing air near the surface of the earth. this precipitation is called a) hail. b) rain. c) sleet. d) snow.
