Andy holds an ice cube in his hand until the cube melts. By that time, Andy's hand has become very cold. What is the most complete description of happened?
The thermal energy from Andy's hand flowed in to the ice cube, melting it.
O The cold energy of the ice cube cancelled out with the heat energy of Andy's hand, cooling his hand
and melting the cube.
As the ice cube melted, the water evaporated via sublimation, cooling Andy's hand.
The ice cube's cold energy flowed into Andy's hand, making his hand cold.

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.
