Answer:
Humans only recently (like in the last 300 years) realized what Gravity is all about. Greek philosophers thought that the planets and stars were part of the gods' realm and followed a "natural motion." They did not realize that Gravity is involved. The Greeks' ideas stuck around until the 16th century. Beginning in the 1500s, though, astronomers like Galileo and Brahe discovered that the earth and other planets revolved around the sun. Kepler showed that they moved in an eliptical orbit, not a circle. The question was why. Sir Isaac Newton -- The Discoverer of Gravity! Sir Isaac Newton was an English mathematician and mathematician and physicist who lived from 1642-1727. The legend is that Newton discovered Gravity when he saw a falling apple while thinking about the forces of nature. Whatever really happened, Newton realized that some force must be acting on falling objects like apples because otherwise they would not start moving from rest. Newton also realized that the moon would fly off away from Earth in a straight line tangent to its orbit if some force was not causing it to fall toward the Earth. The moon is only a projectile circling around the Earth under the attraction of Gravity. Newton called this force "gravity" and determined that gravitational forces exist between all objects. Using the idea of Gravity, Newton was able to explain the astronomical observations of Kepler. The work of Galileo, Brahe, Kepler, and Newton proved once and for all that the Earth wasn't the center of the solar system. The Earth, along with all other planets,orbits around the sun. Two astronomers, J.C. Adams and U.J.J. LeVerrier, later used the concept of Gravity to predict that the planet Neptune would be discovered. They realized that there must be another planet exerting a gravitational force on Uranus because Uranus had odd perturbations in its orbit. (Perturbations are deviations in orbits.) Albert Einstein -- The General Theory of Relativity Einstein developed a whole new idea about Gravity. According to Einstein, Gravity arises from the "warping" of space and time. Einstein's new theory of Gravity explains a number of phenomena that would violate Newton's theory. For example, light bends when passing near massive objects like the Sun. And a clock raised above the Earth speeds up relative to a clock on the surface. Gravity is a force of attraction that exists between any two objects. There is a force of gravity between the sun and the Earth, between the Earth and us, and even between two marbles. Projectiles, satellites, planets, galaxies, and clusters of galaxies are all influenced by Gravity. Gravity is the weakest of the four known forces of nature, yet the most dominant force. Even though it's the weakest force, Gravity holds together entire solar systems and galaxies! The law of universal gravitation says that every object attracts every other object with a force that, for any two objects, is directly proportional to the mass of each object and inversely proportional to the square of the distance between the two objects. The gravitational formula is This is an example of the "inverse-square law": gravitational force varies as the inverse square of the distance between the two objects. As a result, the effect of Gravity falls rapidly as the distance increases between two objects. The best current estimate of G is that it eqauls about 6.67259 10-11 newton-square meter per square kilogram. The gravitational field for a planet, g, equals GM/Rsquared, where G is the mass of the planet and R is the distance of the object from the center of the planet (the planet's radius if the object is on the surface of the planet). This means that Gravity is greater where a planet is more massive and where it has a smaller radius. So even though Mars has only about 1/10th of the mass of the Earth, the gravitational force on the surface of Mars is more than 1/10th that on the surface of the Earth -- because Mars' surface is closer to the planet's surface! The force of attraction between you and the Earth is your weight. Gravity determines the "escape speed" for an object like a rocket. The stronger the gravitational pull of the object, the larger the escape speed. The following chart shows the escape speed for the sun, two planets, and the Earth's moon.
Sun 620 km/s
Jupiter 60.2 km/s
Earth 11.2 km/s
Moon 2.4 km/s
What was a fiefdom ?
Answer:

Explanation:
In at least two sentences, explain the three components of citizenship.
A citizen is a person who belongs to a political society that is governed by a set of duties and rights. He asserts that the three components of citizenship are civil, political, and social which are resumed in the following scheme.
What are duties and rights?A right is a decision to choose your own opinion and an entitlement to things like freedom of expression, religion, and education. Responsibilities are obligations or things a person ought to perform, such obeying the law and following the rules. This is how roles and responsibilities in the classroom are intertwined.
In contrast to obligations, which one should carry out for others, rights are things that one wants other people to do for them. As a result, having a right also entails having to respect the rights of others. Duties are the forms that accompany the rights that come with them.
Some of the moral obligations and duties that come with being an Indian citizen are listed in the constitution: The national anthem and flag must be respected.
Thus, A citizen is a person who belongs to a political society that is governed by a set of duties and rights.

South Sudan, Ethiopia and Cote Devour were among Africa's fastest growing economies in the past few decades posting remarkable economics growth rates. However, a substantial number of people in these countries still live in absolute poverty due to high levels of inequalities. Discuss why this is the case for developing countries.
Answer: The major issues most times is that policies for strategic growth are not well planned to favour the masses instantly and might probably take some years to get everyone enjoying them. But we know that having a sustained economy over a long time is a big task, so the larger population may not enjoy most short progress made until it's over time and rubs off on every other sector
Explanation:
Most developing countries especially Africa, have the issue of development and it not rubbing off on the larger population. Some countries would be in recession and it will later be announced that recession is called off but there won't be much difference when you asked the masses about it's influence. Developing countries have it's wealth enjoyed most times by a lesser population when developing. An example would be some person's involved in food production, and the market favours them but they still awake their product expensive for the larger population to acquire.

It has long been hypothesized that extinction is a natural phenomenon. In fact, it is estimated that of all the species that ever lived, 99% are now extinct. Why then do we say that we are now experiencing an loss of biodiversity (extinction) crisis?
Answer:
Why are we losing the species that currently exist and not giving the opportunity for new species to emerge.
Explanation:
Violent human exploitation of nature, pollution and climate change are causing the death of species, en masse, promoting a very large loss of biodiversity on the planet, without allowing new species to emerge. This is because new species need to evolve from old species, which are being killed these species are dying, there is no evolution. This lack of biological evolution promotes extinction and loss of diversity.

Cultural feature means any building, structure, historic district, area, site or object, including an underground or underwater site, of significance in the history, architecture, archaeology or culture of this state,its communities or the nation and is eligible for inclusion on the State Register or National Register.
Borders of regions or of countries define an area, which has a particular shape and size. Sometimes physical features define the border of a region or a country. ...
