Consider an electric motor with a shaft power output of 22.5 kw and an efficiency of 85%. determine the rate at which the motor dissipates heat to the room it is in when the motor operates at full load. in winter, this room is normally heated by a 2.5 kw resistance heater. determine if it is necessary to turn the heater on when the motor runs at full load

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.
