Conservation of energy

sentry duty may be a state-dependent behaviour and that it allows non-sentries to relax their vigilance and forage more. Understanding how captivity affects behaviours like sentry duty is important for conservation, particularly reintroductions. Key words: sentry, captive, meerkats, behaviour, conservation.…

Capillary Effect 3. Self Perpetual motion 1. Fluid mechanics Fluid mechanics is related to the fluids that are in motion and forces acting on them. Fluid mechanics has two branches fluid statics and fluid dynamics. In Fluid Mechanics we actually observe fluid motion and…

fracking is a dangerous and unnecessary means of obtaining fossil fuel. However; abolishing fracking in our country is impractical because of the money it costs to import natural gases and the fact that natural gases are a key component in keeping the energy surging in our lives, home, and nation. The extraction of natural gases and resources has been a method that has evolved over the years; there are many different aspects to harnessing these resources including fracking. “Vertical drilling”…

it's next to impossible not to hear about our record-breaking drought. http://www.care2.com/causes/7-things-that-might-surprise-you-about-californias-drought.html But if you're not from California or another drought-stricken state, then water conservation might not be as high of a priority -- it's not affecting you, so why should you care? Well the new "Water Hog" campaign shows how drought is everyone's problem -- including wildlife -- and offers consumers easy, water saving tips. Every Drop…

Rosseland Radiation Model The Rosseland Model (Diffusion approximation model) is applicable when the medium is optically thick i.e. the optical thickness is much greater than 1 where a is the absorption coefficient of the medium, σ is the scattering coefficient of the medium and L is the average path length. The radiative heat flux is approximated as [3], (2.13) where qr is the radiative heat flux, Γ is the radiative diffusivity and G is the incident radiation. In contrast to the P-1 model…

To Be Named: The Glass Menagerie by Tennessee Williams The title, The Glass Menagerie, is the first “name” that is encountered, and a menagerie is “A collection of wild animals in cages or enclosures, esp. one kept for exhibition, as in a zoo, etc. Also: a place or building in which such a collection is kept.”(OED). By this definition, the characters are like the wild animals as they are trapped together because of financial reasons, family bonds, and because they are stuck in Tom’s memory. By…

Newton’s 3 laws of Motion 1. If a body is as rest it remains at rest or, if it is in motion, it moves with uniform velocity, until it is acted on by a resultant force. 2. Acceleration is dependent on the forces acting upon an object and the mass of the object. Therefore, if the force is increased, the acceleration is increased. And the more mass the object has, the more acceleration decreases. So the resultant force (F) is equal to mass (m) times acceleration (a) (F = ma). 3. For every action,…

constants, and the energy that was being used. Once that was done the catapult had to be made and tested on angle and how far it could firer. Then it was ready, ready to fire and reach for the skies or maybe ten points. All because physics was put into play. More specially the principle of energy. To make a catapult that could send a skittle through the air and into a bowl to reach its goal an energy had to be used, that energy was elastic energy. So what is elastic energy. Elastic energy is a…

And we won’t admit it. According to the International Union for Conservation of Nature there is around 16,000 species at risk of extinction and 41,415 species that are threatened. Many species including ourselves are in danger if we do not look for a solution to prevent it. In Andrea Wulf’s The Invention of Nature, she introduces Alexander von Humboldt who was the first scientist to notice climate change. Today, it is a big topic since we can see it occur in front us or on the news such as and…

journalist Elizabeth Kolbert discusses New Zealand’s problem with invasive species attacking endemic fauna which results in many of their native species becoming extinct. Kolbert explains the problems of exterminating specific animals such as stoat for conservation of their natural wildlife. She also explains the issues of how explorers brought various animals to different parts of the world. Hence, Elizabeth Kolbert discusses the difficulty of eliminating invasive species and that extreme…
