Kepler devised three laws to explain: B) <em>the motion of the planets.</em>

According to the first law, a planet revolves around the Sun in a path similar to 1) <em>an ellipse</em> with the Sun fixed at one of its focus points.

<em>Johannes Kepler(1571-1630)</em> was an astronomer who discover the three laws of planetary movement.

These are the complete set of laws that describe the motion of planets.

1.- The Law of Ellipses. The path of the planets about the sun is elliptical in shape, with the center of the sun being located at one focus.  

2.- The Law of Equal Areas. An imaginary line drawn from the center of the sun to the center of the planet will sweep out equal areas in equal intervals of time.

3.- The Law of Harmonies. The ratio of the squares of the periods of any two planets is equal to the ratio of the cubes of their average distances from the sun.

Describe why the need for raw materials led to further state expansion.
Alexus [3.1K]

The correct answer to this open question is the following.

The need for raw materials led to further state expansion, following the Manifested Destiny that was the belief for many Americans that God's will was for America to expand its territories. After the Louisiana Purchase of 1803, US President ordered the Lewis & Clark expedition to the new Western territories. When the exédition was over, those explorers went to Washington D.C. to inform the President about the results. That is when Jefferson authorized people to settle those territories, work the land, and exploit the many raw materials and natural resources to get a profit.
