Answer:
Scientific investigations produce evidence that helps answer questions and solve problems. If the evidence cannot provide answers or solutions, it may still be useful. It may lead to new questions or problems for investigation. As more knowledge is discovered, science advances.
The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.
The two variables are "mass and distance".

<span>In discovery science, you make observations or analyze data, usually a large amount, to see what kinds of patterns you can find. If you do think you find patterns or other information, you may form a hypothesis and test it traditionally.
In hypothesis-based science, you form an educated guess, or hypothesis (which is almost always based on previous observation), then devise a way to test that hypothesis in a controlled fashion.</span><span>
