The correct answer is A) three laws of motion and E) Force of gravity.
The two scientific theories developed by Newton were three laws of motion and Force of gravity.
Isaac Newton (1642-1727) was an English mathematician and scientist during the Scientific Revolution. He discovered the "Three Laws of Motion" that he explained in his document "Mathematical Principles of Natural Philosophy." In this work, he also developed the mathematical description of the fore of gravity. The first law is the "law of inertia." The second law is the acceleration is produced when a force acts on a mass, and the third one is that for every action there is an equal but opposite reaction.
The other options of the question are B) position of the Sun in the Solar System, C) laws of chemistry and D) position of the Earth in the Solar System.
