Important To Note Amount Of Energy
1,728 wordsThere are nine planets in our solar system and we have visited all of these but one. Even though Pluto is the smallest and furthest planet from the sun, it is no way inferior to the other planets. It in fact is possibly one of the most unique bodies in the solar system. There is much that we do not know about this tiny world and its equally unique moon, Charon. For this reason we are proposing to send a flyby mission to the Pluto-Charon system as soon as possible. Pluto was discovered on Februar...

Source Of Energy Solar Cells
970 wordsSpace is filled with radiant energy and beyond earth's atmosphere this energy flow more steadily and more intensely from the sun than that which penetrates to the surface of the Earth. So an abundant and essential source of energy that would be used in space for the space colony would be solar radiation by developing satellite solar power stations. To live in space, humans must be protected from the fierce intensity and penetrating wavelengths of unattenuated sunlight, but this same energy is on...

Valence Electrons Solar Cells
1,438 wordsIntroduction Our world has been in existence for billions of years and throughout all those years we have used the sun for basic energy needs. So why not be able to harness that energy and use it to power things like our homes or our cars? Many scientist have been developing alternate forms of energy called Green Energy. Green power is the solution to creating a cleaner, sustainable energy system. Renewable energy -- power from the sun, wind, plants, and moving water -- is a natural way to meet ...

Source Of Energy Valence Electrons
1,486 words... holes, is achieved by the incorporation into the silicon of atoms with 3 valence electrons, most often boron and n-type doping, the creation of extra electrons is achieved by incorporating an atom with 5 valence electrons, most often phosphorus (see figure 2). Figure 2 Silicon Crystal Lattice with Dont Atoms. Once a p-n junction is created, electrical contacts are made to the front and the back of the cell by evaporating or screen printing metal on to the wafer. The rear of the wafer can be ...

Volcanic Eruptions Greenhouse Gasses
8,580 wordsThis Climatic Change I. SUMMARY: This paper looks at the controversial issue of climatic change. In particular, it develops the question of if and why earth? s climate is changing? The roles of man, naturally occurring trends, and earth? s cycles are considered, and an outlook for what can be expected in the near and distant future is given. ? The uneasiness of modern man arises from a rupture between himself and nature that leaves him homeless within the universe? William Barrett II. INTRODUCTI...

Planet From The Sun Center Of The Universe
2,375 wordsAssignment 1: The Solar System The solar system consists of the Sun; the nine planets, 67 satellites of the planets and a large number of small bodies (comets and asteroids). The inner solar system contains the Sun, Mercury, Venus, Earth and Mars: The planets of the outer solar system are Jupiter, Saturn, Uranus, Neptune and Pluto: The orbits of the planets are ellipses with the Sun at one focus, though all except Mercury and Pluto are very nearly circular. The orbits of the planets are all more...

Planet From The Sun Outer Planets
2,417 wordsThe Solar System consists of the Sun, the nine planets and their satellites; the comets, asteroids, meteoroids, and interplanetary dust and gas. It is composed of two systems, the inner solar system and the outer solar system. The inner solar system contains the Sun, Mercury, Venus, Earth and Mars. The outer solar system contains Jupiter, Saturn, Uranus, Neptune and Pluto. The inner planets are relatively small and made primarily of rock and iron. The asteroids orbit the sun in a belt beyond the...

Renewable Energy Sources Fossil Fuels
2,607 wordsEnergy is one of the most fundamental parts of our universe. We use energy to do work. Energy lights our cities. Energy powers our vehicles, trains, planes and rockets. Energy warms our homes, cooks our food, plays our music, gives us pictures on television. Energy powers machinery in factories. Energy is defined as the ability to do work. When we eat, our bodies transform the food into energy to do work. When we run or walk, we burn food energy in our bodies. When we think or read or write, we ...

Gas And Dust Solar System
893 wordsOrigin Of The Solar System For more than 300 years there has been serious scientific discussion of the processes and events that led to the formation of the solar system. For most of this time lack of knowledge about the physical conditions in the solar system prevented a rigorous approach to the problem. Explanations were especially sought for the regularity in the directions of rotation and orbit of objects in the solar system, the slow rotation of the Sun, and the Titles-Bode law, which state...

Valence Electrons Solar Cells
1,194 wordsSolar Energy Solar cells today are mostly made of silicon, one of the most common elements on Earth. The crystalline silicon solar cell was one of the first types to be developed and it is still the most common type in use today. They do not pollute the atmosphere and they leave behind no harmful waste products. Photovoltaic cells work effectively even in cloudy weather and unlike solar heaters, are more efficient at low temperatures. They do their job silently and there are no moving parts to w...

Municipal Solid Waste Fossil Fuels
2,779 wordsSources of Energy Have you ever thought about how we get the energy to run the things we take for granite every single day. There are many sources of energy that that are used for transportation, heat, light, and the manufacturing of goods of all kinds. The development of science and civilization is closely linked to the availability of energy in useful forms. The seven main energy sources are fossil fuels, hydroelectric, solar power, win power, geothermal, nuclear power, and biomass energy. By ...

Weather prediction has become increasingly accurate with the advancement of technology and should continue to get better. For the majority of people following the weather has become a routine part of their lives. As a society we seem to be well educated about the weather occurring on our own planet but we know ...
