Once known as the ninth planet of the solar system‚ Pluto is now the second-largest dwarf planet. Composed primarily of ice and rock‚ Pluto took part of our Solar System for 76 years. It was discovered on January 23‚ 1930 by Clyde Tombaugh. Tombaugh was an American astronomer who worked at the Lowell Obeservatory. Tombaugh had been working on a project when he came across a moving object in photographs he had taken of the celestial sky. After observing a lower quality picture taken of the mysterious

Conservation of Energy In explaining the laws of conservation of energy‚ energy cannot be destroyed or made. Although‚ energy can be transformed or transferred from one form to another‚ for example: The total amount of energy in any system never changes but stays constant over time. Second example: Coal is burned‚ and then used as thermal energy for heat‚ next the steam is used for mechanical energy. Energy is never destroyed but changed to forms like thermal energy‚ gravitational energy‚ electromagnetic

planet in a tiny part of a vast universe. "This part of the universe is called the solar system‚ and is dominated by a single brilliant star-the sun." (Skywatching 230) The solar system is the earth ’s neighbourhood and the planets Mercury‚ Venus‚ Mars‚ Jupiter‚ Saturn‚ Uranus‚ Neptune and Pluto are the Earth ’s neighbours. They all have the same stars in the sky and orbit the same sun. Scientists believe the solar system began about 5 billion years ago‚ perhaps when a nearby star exploded and

If every one would drive hybrids and electric cars we would not have problems like the one we are having now in the Gulf of Mexico. Another significant way to save money is solar energy‚ and wind energy. Solar energy is solar panels converting our sun rays into electricity by photovoltaic cells. The solar panels are intended to reduce both air pollution and CO2 emissions. Many people have found this new energy saver very useful so many of them have put them to work in their houses

In 1993‚ Quantum Devices Inc. (QDI) teamed with WCSAR (Wisconsin Center for Space Automation and Robotics)‚ a NASA center for the commercial development of space‚ developed High Emissivity Aluminiferous Light-emitting Substrate technology to provide high-intensity‚ solid-state LED lighting systems for NASA Space Shuttle plant growth experiments. Their goal was to be able to grow plants in space so humans could have longer stays in space shuttles or the International Space Station (ISS). They discovered

First Solar Turns Sunshine into Profits Case Summary: First Solar was founded in 1999 from the Walton family. According to the Marketing Sun Power‚ First Solar’s mission is “to create enduring value by enabling a world powered by clean‚ affordable solar electricity.” (p. 90) The company manufactures solar modules‚ which have razor-thin cadmium telluride. They are manufactured this way because it can still produce electricity even when clouds are blocking the sun. With this product First Solar
