<h2>1. Right answer: Observational
</h2>
Kepler formulated the three laws of planetary motion <u>from observations made by</u> the Danish astronomer <u>Tycho Brahe of the orbit of Mars.
</u>
These laws were enunciated to mathematically describe the movement of the planets in their orbits around the Sun. However, the scientific resources existing in his time did not allow him to prove these laws. It was Newton who did it after having developed the Differential and Integral Calculus and formulating the Laws of Universal Gravitation.
<h2>2. Right answer: Aristotelian
</h2>
Aristotle mistakenly thought that the Earth was the center of the universe, thus establishing a <u>geocentric cosmological model.
</u>
According to this model, Aristotle proposed that the universe (the cosmos) was spherical and finite, with the Earth immobile at its center, composed of the four fundamental elements (made up of spherical layers): ground, water, air and fire; and the Sun along with the fixed planets in their respective concentric spheres revolving around the Earth. The outermost sphere being that of the stars and all these external elements being made of a fifth element which he called ether.
The correct answers are:
- They are made of denser objects, which can condense at relatively high temperatures;
- They are made of heavier elements, which have a stronger gravitational attraction to the Sun;
All the planets in the Solar system formed from the solar nebula. The conditions though were different for the formation of the planets. The gas giants were not able to form closer to the Sun because of the high temperatures, and those temperatures were not allowing the lighter mater to condensate. On the other hand, those same high temperatures enabled the heavier, denser materials to be able to condensate, thus giving rise to the terrestrial planets.

It should be noted that the angular momentum remain constant and kinetic energy of the skater increases.
<h3>What is Angular momentum?</h3>
Angular momentum can be regarded as the property of any rotating object given by moment of inertia times angular velocity, since No net torque is done on the object, then angular momentum is constant.
Kinetic Energy which is also the energy of motion in the Ice skater will increase since their is a pull.
