Suppose you have two black square plates, each at the same temperature, that are placed face to face with a small gap between them. They are both perfectly black and so absorb all electromagnetic radiation incident upon them but suppose one of the plates is emitting twice the radiation of the other. Explain why this would violate the second law of thermodynamics.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
