Energy Star Rated Homes Have you ever heard the expression “saving money is making money”? If someone offered to put hundreds of dollars a year in your pocket would that interest you? In this paper, we will discuss how it is possible to not only put money back in your pocket each year but also how you can do your part to make our environment a healthier and more environmentally friendly place. This is all made possible by owning an Energy Star Rated Home (ESRH). My goal is to bring to light the
The energy drink industry over the years has been quite sustainable and really does not have any chance of taking any major loss in revenue anytime in the near future. Companies like Red Bull, Monster, and Rock Star will always be in direct competition with one another. Some of the strengths of this industry is the status in which all of the most prominent brands of energy drinks uphold to. They all use a number different branding strategies and marketing techniques that distinctly set them apart
Introduction Humidity and wet conditions inside your home can lead to all sorts of problems. If they’re not taken care of, it can lead to health issues. While some areas aren’t known to be humid, there is still in the air, especially in basements of homes. If you have a basement, water can get into it and allow fungus and bacteria to flourish. By installing a dehumidifier in any wet area, you’ll decrease the amount of moisture and prevent them from becoming a larger issue. You’re probably wondering
INTRODUCTION Sustainability proposes that socially responsible firms will somehow financially outperform other less responsible firms in the long run resulting from customer loyalty, better employee morale, or public policy favouring ethical conduct. Empirical results testing this hypothesis are mixed, neither suggesting that more responsible firms, on the average, have a clear financial advantage nor a large burden. A useful approach is to determine specific circumstances under which a firm
The beautiful twinkles of light in the night sky are stars. How did these sparkles of light come about? What role does physics play in the life of a star? To understand the physics of stars we must take a look at gravity, nuclear fusion, supernovae, and neutron stars. Gravity is important in the formation of stars. A protostar, the earliest stage of a star, is formed from dust and gas from a nebula clumping together. The gravity pulling in is greater than the pressure pushing out. As more matter
beyond, wondering what secrets the stars held from them. The mass of stars compared to our sun is a frequented question by many astronomers. The answer lies within the luminosity and mass of the star. There are 2 different ways humans can calculate the mass of stars, both using luminosity. One way is to calculate luminosity with radius and temperature of the star being observed. Another much simpler way is to convert apparent magnitude, the brightness of the star observed from earth, to absolute magnitude
The Lifecycle of Betelgeuse The Star Betelgeuse is classified as the ninth brightest star in the night sky and is the second brightest star in Orion's’ constellation. Betelgeuse is a very unique star in the sky when it is compared to other stars.Betelgeuse is classified as a high mass star. Some introductory facts about the star include its luminosity, which is 140,000 suns, temperature is 3,488 Kelvin, its distance from the sun is 640 light years, radius compared to the sun is 667 times the sun
A star is a self-radiant divine body consisting of a mass of gas held together by its own gravity. The birth of a star begins inside a molecular cloud. Stars form inside these somewhat dense concentrations of interstellar gas and dust. The process of star formation has long been a mystery because of viewing limitations. Large amounts of small solid particles blocked our view of the stars which are beyond the molecular cloud. Infrared technology now provides some insight on how a star is formed
Shaviv and Oded Regev at Tel Aviv University and then Technion-Israel Institute of Technology in Haifa. These scientists use supercomputers to study the effects of various collisions. They concluded that if a sun like star was hit by a white dwarf 10 million times as dense, the sun like star would be destroyed and only minor warming would take place on the outside of the white dwarf. If the sun were to go through this type of collision it would not annihilate the earth but would cause all the water in
‘There are more stars than all of the grains of sand on earth.’(Star Facts, 2005:1) Looking up at the sky on a vibrant night, the vision is naturally lit one with millions of vivacious, glistening stars. The tenacity of this essay is to explore the lifecycle of a star, thence, signify its manifestation in the universe. A fundamental part of our universe is stars. Hence, these miniature luminous forms are essentially very immense in magnitude and it is merely due to their substantial distance from
depending on where the observers are located. History: The constellation Orion is named after a giant huntsman in Greek Mythology. The arrangement of the stars somewhat resemble a hunter holding a shield or lion. To the east and south are his hunting dogs Canis Major and Canis Minor with whom he fought the bull Taurus. There are several star stories from many cultures written of Orion. One of the more common
Stars are luminous spheres that have been around longer than humans. In fact, it has been said that, “We are a way for the universe to know itself. Some part of our being knows this is where we came from. We long to return. And we can, because the cosmos is also within us. We're made of star stuff.” [1] Just like any other animate object, stars also go through a life cycle. They grow up, live their life, and slowly but surely die out. Stars can live for billions and even trillions of years. The
Although the space between stars appears to be empty, it is actually filled with matter known as the interstellar medium, approximately ninety-nine percent of the interstellar medium consists of gas and the remaining one percent is dust. Clouds of interstellar medium are called nebula, derived from the Latin word for cloud (What is the Interstellar Medium?, n.d.). Nebulas are formed when gravitational attraction clumps together parts of the interstellar medium (Villanueva, 2010). There are several
Quasar could only be a few light days across. This again, led to more questions of how Quasars work. How could something so small put out so much energy and be so bright. “Astronomers were faced with a conundrum: how could an object about the size of the solar system have a mass of about a million stars and outshine by 100 times a galaxy of a hundred billion stars?” (Britannica.com) The answer that astronomers eventually came up with is accretion of gravity onto a supermassive black
at the sky at night and see the stars. But what are those little white dots? We know that stars give off light, but most people do not know that stars are composed of atoms. We know that stars are made up of atoms because of the light they emit due to nuclear reactions from atoms within them. Scientists are also able to observe spectral lines when looking through a telescope with a spectrometer attached. They are able to tell based on these spectral lines that stars are made up of mostly hydrogen
The definition of a supernova is; An explosion of a star that has reached the end of its life. There is a lot more to it than that. Supernovae can be triggered in one of two ways: by the sudden re-ignition of nuclear fusion in a degenerate star, or by the gravitational collapse of the core of a massive star. Once a supergiant can no longer sustain nuclear fusion, it explodes in a massive supernova. As fusion slows inside the star, it collapses towards its core. Gravity forces the gases and metals
well. If an astronomical object is moving away from the Earth, its light will be shifted to longer (red) wavelengths. This is significant because this theory indicates the speed of recession of galaxies and the distances between galaxies. How do stars form? Small regions within an instellar cloud about a fraction of a light year across begin to collapse under their own gravity. As the collapse continues, the center of this core region becomes denser and denser climbing from only 100 atoms per cubic
evolution refers to the changes which stars undergo during their lifetime. Stars change in color, luminosity, size and temperature through their lifespan. Scientist can not study an individual stars lifetime though because they far exceed ours and therefore we must study stellar evolution by observing the life cycle of numerous stars, each at a different point in its life cycle, and then running computer models which simulate the structure of stars. Through history stars have been recorded, starting with
Stars are born within clouds of dust and swirling wind in our atmosphere. The turbulence within these clouds creates enough gravitational force between the gas and dust that it begins to collapse upon itself and becomes more dense and hot further into the cloud. The cloud continues to collapse, collecting dust and gas around the hot center which is called a protostar. (http://science.nationalgeographic.com) Protostars are not hot enough to emit visible light in their early stages, but emit infrareds
Everything in the world dies, even stars. A supernova occurs when a star “dies.” A supernova is the explosion of a star. These explosions release huge amounts of energy, an amount equivalent to a few octillion nuclear warheads, or one million tons of TNT. One supernova will radiate more energy that our son will its entire lifetime. Supernovae play a huge part in the galaxy by being a primary source of heavy elements in the universe Throughout a large stars life, they create heavy elements within
