Which statement is correct? theories are accepted as true when a single experiment yields similar results to another one. when a scientist finds a new way to test a hypothesis, experimental methods do not change. theories may be revised over time as information is discovered or technology is developed. when a scientist finds a new way to test a hypothesis, the original theory is made into a law.

Theories may be revised over time as information is discovered or technology is developed.

Explanation:

A scientific theory is a set of knowledge related to a particular problem of interest, be it academic or practical. The structure of a theory is formed by the following main elements: problem, evidence, postulates, axioms, questions, hypotheses, predictions, theses, rules and laws. Theory seeks to explain a particular phenomenon or problem of society, so theories can be revised and change as society changes and new technologies and new information are discovered.

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.
