A horizontal force of 7000N is applied to vehicle of mass 400kg which is inifidly addres at a horizontal surface. if the total force opposing the motion is constant at 800N (a) calculate, aceleration of the vehicle (b) kinetic energy of the vehicle after 5 seconds after the force is applied (c) total power developed after force applied (5 seconds)

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.
