According to Newton's third law of motion . every action has an equal and opposite reaction all masses have a gravitational force the more mass an object has, the more inertia it has an object at rest will remain at rest unless acted upon by an outside force

One form of energy can be another type of energy. a. created to form b. transformed into c. destroyed and then created to form

Air is to be preheated by hot exhaust gases in a cross-flow heat exchanger before it enters the furnace. air enters the heat exchanger at 95 kpa and 20°c at a rate of 0.6 m^3/s. the combustion gases (cp = 1.10 kj/kg°c) enter at 160°c at a rate of 0.95 kg/s and leave at 95°c. determine the rate of heat transfer to the air and its outlet temperature.

Area around a charged object where the objects can exert a force on another charged objects is an electric
