Primary energy

1. In one to two paragraphs, summarize the secondary source for which you completed the Secondary Source Analysis Worksheet in learning block 2-4. Focus on the secondary source’s thesis, arguments, use of primary sources, potential biases, reliability, and usefulness to a beginning researcher. In the article, the Search for Middle Ground written by J. Samuel Walker, the author J. Samuel Walker addresses a chronically and fueled debate between many well-known scholars about Truman’s decision to…

Solar Energy The sun is the most abundant energy source available and used on Earth, hands down. The problem is, much of the energy from the sun that is used on Earth is used by primary producers, not by us, and what they do use is an incredibly small compared to the 89,300 TW retained on Earth at any instant. What we use is smaller still (22). The first step in harnessing the awesome potential our very own star is understanding just how to do that. Think of the inside of a solar cell, the…

affect the energy given out. Introduction Dissolving is when a solute is mixed into a solvent to form a solution. Dissolving can be either endothermic or exothermic. Endothermic reactions happen when the energy given out when bonds are broken, is greater than the energy given out when bonds are made. As more energy is used and taken in, the surroundings become colder. Dissolving is exothermic when energy is given out to its surroundings. In an exothermic reaction bonds are being made. The energy…

way to transfer heat energy from the chip to the water beaker. The heat transfer was coming from burning a baked lay and through our calorimeter heat energy was pushed out. Our experiment was taken one step further to continue to modify and build a better calorimeter. Overall the purpose was to find the best way for energy to be captured. Literature Review Anything around us is generally matter. Everything we touch, the buildings we see, and the cars we ride in. “Energy is the ability to…

In order to survive under several environmental influences, animals must possess biological mechanisms which enable them to regulate and maintain their internal environment. Temperature is one of abiotic factors that are inexorably linked to every animal’s physiological functions since it is considered a strong source of selective pressure on animals (Miller, 2010). Animals are categorized into thermoregulators and thermoconformers based on their mechanisms to maintain their internal environment…

physics background. This would be a stepping-stone to future technologies. For example, a small hand held HPM weapon would allow soldiers to eliminate visible or nearby enemy electronics without need for aerial support. Code 35 also has a directed energy division that interests me, the Applied Electromagnetics…

maintain the generated heat within their systems to maintain their bodies at a constant temperature. If temperatures increase or decrease above or below the desired constant temperature or thermo neutral zone, these organisms have to do work and spend energy in order to reach a constant metabolic rate. The metabolic activity seen among both endothermic and ectothermic organisms varied in the different environmental…

variations, depending on how easily it is to get the ball warm and bouncy. The type of ball used is determined by the player’s skill level. Squash mainly uses fitness components that include, agility, anaerobic capacity and muscular power. The dominant energy system that squash players use is the Lactic Acid System. The fitness component Agility is the ability of the body to remain balanced whilst changing direction. It is vital for squash players to be agile. Agility is used in squash when the…

In the dynamic firefighting service leaders often times find their department in need of adaptive change. This change could be driven by a change in the economics, municipal policies, inter-department policies or perhaps a new leader with a new vision. None the less, change is needed in order to meet the new needs of the department. Often times, this change is an adaptive change that no simple answer by following standard operating procedures or hiring a consultant. Solutions to adaptive change…

considered it just a mathematical trick to make his equation work. Having worked with classical physics all his life, he was used to looking on light as a wave and using wave-based equations to accurately predict its behaviour. His ‘imaginary’ discrete energy packets had no place in this structure. Planck’s equation was not, at first, very popular. The rest of the physics community had the same problems with it as he did, the fact that he had to use a mathemagical trick to get the right curves…
