<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.

Answer:
Because Water is not a buffer solution and the acetic acid/acetate solution is a buffer solution. An acidic buffer is a solution of a weak acid (acetic acid) and its conjugate base pair (sodium acetate) that prevents the pH of a solution from changing drastically through the action of each component with incoming acid or base.
The workdone by the tension is; Positive
<h3>What is Tension force?</h3>
This question is from an elevator that is held by a single cable which is ascending but slowing down.
Now, this elevator is being acted upon by two vertical forces known as Tension which is upwards and the weight of the elevator acting downwards.
However, the direction of motion of the elevator is in the same direction as the tension in the cable. Thus, we can say that the work done by tension is positive.

An Economic Good that I have used today is a laptop and an Economic Service that I have used today is bank.
Economics can be defined as a field of science that is focused on the analysis and examination of various principles that influence the production, demand and supply of goods and services.
