Essay On Nuclear Energy And Advantages And Disadvantages
Dynamite was invented by Alfred Nobel in order to develop the industry of getting minerals and digging tunnels; however, Dynamite is now widely used in military purpose. Similarly, nuclear energy is undoubtedly a powerful source of energy compared to other conventional fuels such as coal, oil and gas. However, nuclear energy also has a lot of disadvantages, such as nuclear wastes, nuclear plant accidents and nuclear weapons. So before widely use this technology, both pros and cons should be taken…...

Direct Exchange Geothermal
Direct exchange geothermal heat pump The Direct exchange geothermal heat pump is the oldest type of geothermal heat pump technology. It is also the simplest and easiest to understand. The ground-coupling is achieved through a single loop circulating refrigerant in direct thermal contact with the ground (as opposed to a combination of a refrigerant loop and a water loop). The refrigerant leaves the heat pump appliance cabinet, circulates through a loop of copper tube buried underground, and exchanges heat with…...

Slider Crank Lab Report Politeknik
Crank and Connecting Rod Introduction- The motion of assemblies is determined by the configuration of links and joints. Using the configurations the operation of rotational and sliding joints are examined and observed. This kind of mechanism is very commonplace in machines. Machines are made up of a number of parts and relative motion between the various parts permits the working of the machine. As the crank is rotated the rod starts moving but the velocity is not uniform. It is…...

Energy Conservation Essay
Conserving energy is very important because there is a limited amount of nonrenewable energy sources available on earth such as coal, oil, and gas. If people do not conserve the nonrenewable resources we have now, there might not be any left for future generations. In addition, energy conservation is important because when nonrenewable energy sources are consumed this impacts the environment. The combustion of oil, gas, and coal in power stations produces carbon dioxide and contributes to global warming. The…...

Calculus Basics: Limits, Functions, Derivatives, Integrals, and Series
Calculus is the study of change which focuses on limits, functions, derivaties, integrals, and infinite series. There are two main branches of calculus: differential calculus and integral calculus, which are connected by the fundamental theorem of calculus. It was discovered by two different men in the seventeenth century. Gottfried Wilhelm Leibniz – a self taught German mathematician – and Isaac Newton – an English scientist – both developed calculus in the 1680s. Calculus is used in a wide variety of…...

Background: Momentum is a measure of inertia and can be defined by “mass in motion” ( Stan brought ,) anything with mass that is moving has momentum. Mo momentum can be calculated with p=mass x velocity, there fore momentum is dependent on both mass and velocity. Momentum is similar to energy in that both are always conserved, but energy ha s multiple forms and has to be in the right situation to be conserved. M momentum transferred is the integral…...

As there were five similar experiments done, there is one common observed behavior – similar charges repel and opposite charges attract. The experiment went expected as there were no unusual observations recorded. In the first part, it was observed that when the plastic rod was rubbed it attracted the tissue bits. The explanation with this is, when the plastic rod was rubbed, it became electrically charged. Conduction happens when the tissue paper was rubbed into the plastic rod. The tissue…...

Effect Of Air Conditioner On Global Warming
Air Conditioning and Global Warming Air conditioning systems use energy to remove heat from a given location, transferring it to the exterior in the form of exhaust. Some of the energy is invariably wasted as heat, and this additional heat must also be exhausted. Thus, air conditioning results in net heat release to the environment. The warming effect is aggravated, moreover, because higher forms of energy such as electricity are used to power air conditioners. Generating and transmitting this electricity…...

Hooke’s Law Experiment Conclusion
The aim of this experiment is to investigate Hooke’s law for simple springs of rubber. The relationship between a load force and a light spring (F=k. x) was first determined by Robert Hooke in the 17th century. Where F is the force applied to the spring, k is the spring constant, and x is the extension of the spring. Hooke’s law states that when an elastic material is subjected to a force, its extension (x) is proportional to the applied…...

Magnesium and Copper’s Potential Energy Difference
Magnesium, due to its reactivity, has a very high potential energy, so the electrons travel from it to the copper, which has a very low potential energy due to its unreactivity. The difference in the potential is called the cell potential difference. If the difference of potential energy is large, then clearly the voltage produced by the galvanic cell will also be large as voltage is potential difference. From the electrochemical series, magnesium has a standard electrode potential of -2.…...
