Which two scientific theories were developed by isaac newton? three laws of motion position of the sun in the solar system laws of chemistry position of earth in the solar system force of gravity

The correct answers are A. Three laws of motion and E. Force of gravity.

Explanation

Isaac Newton was a seventeenth-century English physicist who stood out for the content of his book Principia in which he established the principles of gravitation and classical mechanics (Newton's laws). The laws of the force of gravity were developed empirically by Newton when he saw an apple fall from a tree which caused him to wonder why the bodies were attracted to the earth. On the other hand, Newton's laws, or laws of motion are: the law of inertia, which states that a body cannot by itself have its initial state at rest or movement; the second is the fundamental law of dynamics that states that the acceleration of a body is proportional to the force applied to it; Finally, the third law is the law of action-reaction, which states that when a body A exerts a force on an object B, it receives a force of equal magnitude from object B. So, the correct answers are A. Three laws of motion and E. Force of gravity.

the right answer is the third one: turnpikes went short distances to connect markets. turnpikes, also known as toll roads, were very important for trade and transportation (of people, goods and products) in the 19th century, coinciding with the expansion towards the west. they contributed significantly to the economic development of the united states.
