Explain why and how theories may be changed or replaced over time.

Science is always changing and due to this new evidences discovered and theories will be updated and changed.

Explanation:

A theory can change or update with the time. There is no theory which can be consider as the absolute truth. A theory which is useful has been tested by the scientists and give the conclusion about that theory on which majority of scientists agree.

As known that science is a field which always changing with time. Whenever a new evidence is discovered then after that the theory might be change or it will be updated.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
