owe their lives to the deaths of stars? • These stars created us occurring to science. 2. What's a nebula? • A cloud of dust, hydrogen, helium, and gas. 3. Explain the process by which a star is formed. • Gas and dust form in a size 10 times our solar system. 4. What creates a star’s heat/energy (use the words hydrogen and helium in your answer). • Burning hydrogen and converting it into helium. 5. What's the most common type of star? • Red Dwarfs. 6. Why do bigger stars die faster than…
What is the solar system? The solar system is the what we call home, it is the collection of the eight planets and their moons. These celestial objects orbit around the sun, although this was not always the case back in 140 AD Claudius Ptolemy contemplated with the idea or theory of a geocentric universe. The literal definition of geocentrism is having the earth as the center of the universe and the at the other celestial objects orbiting the earth. Theses celestial objects are called planets.…
With the help of Tycho Brahe's observations, Kepler discovered that the orbits of the planets can be described with a curve. By trial and error, he discovered that an ellipse with the sun could accurately describe the path of a planet about the sun. Ellipses (which does not look like the usual circle, but as an egg) is described mainly by the length of its two axes. A circle has the same diameter if we measure it across or up and down. However, an ellipse has diameters of different lengths. The…
An impact basin or impact crater is defined as the circular depression in the surface of a solid body in the solar system such as moon or some other planet. A lunar impact basin is a depression / cavity caused by a meteor or comet hitting the Moon with a greater speed. Impact basins typically have raised rims and floors that are lower in elevation than the surrounding surface. There are over 40 impact basins on the Moon. These basins were created by extremely powerful impacts, which usually…
Pluto We know Pluto as the dwarf planet that had its planetary status revoked. We know it as the distant 9th planet in our solar system. We know it as the planet billions of miles away from the sun. Even though all of these facts about pluto might be right, we do not know so much about this glorious planet. Pluto is a dwarf planet that was discovered at the beginning of the twentieth century. Over the years, there has been much debate over whether or not we should qualify Pluto as a planet,…
“We have a metal building with a gas furnace located above a lay-in ceiling. The local AHJ is telling us that we are required to have sprinklers above the ceiling since there is a gas furnace above the ceiling. Are sprinklers required?” In response to your question we have reviewed NFPA 13, 2010 edition that you indicated as the applicable standard. Our informal interpretation is that sprinklers are not required. The commentary in the 2010 edition of NFPA 13 Handbook under Section 8.15.1.3…
the car will be made, but it will serve as a decent sample. The car itself will depend on three main power sources: solar power, wind power, and kinetic energy recovery, or more commonly known as regenerative braking. The solar panels will cover the top of the car, which is about 105.214 feet squared, or about 9.775 meters squared (Model S). However, the windows cannot have solar panels on them as they would make it impossible for the driver to see out of them. With an estimation, this would…
Neon is one of the world’s rare and most expensive elements. I chose Neon because of it's uniqueness. In 1898, William Ramsay and Morris Travers at University College London isolated krypton gas by evaporating liquid argon. They had been expecting to find a lighter gas which would fit a niche above argon in the periodic table of the elements. They then repeated their experiment, that time allowing solid argon to evaporate at a slow pace under reduced pressure and collected the gas which came off…
Mercury, Venus, Earth, and Mars are known as the terrestrial planets. In comparison to the outer planets, they are small in size, made of denser materials, and lack a huge numbers of moons. Even though they share these common traits, they are still very different from each other. Mercury is the closest planet to the sun, yet its surface is either extremely hot or extremely cold due to the slow rotation of the planet on it's axis and the lack of atmosphere. It is also unique in that it's core is…
different technology forms. One is wind power. They whole use turbines to catch the wind and transfer it to power. Another way is solar. They would use solar power panels to turn sun rays into power. There are actually two different types of solar panels. One is called a solar PV that just goes on the roof or a yard to generate enough power for the house. Another is called a CSP solar panel. This panel stretches across a plain and gives enough power for almost all of Australia. The third one is…
