Uganda provides a perfect example of an energy poverty country and therefore, I recognize its need for talent in form of planners and experts in fields that are critical to economic development. My greatest challenge is in helping Uganda cope with the paucity of personnel...
Before the industrial revolution, humans relied on natural energy flows and animal and human power for heat, light and work. Draft animals, wind and water were the only sources of mechanical energy. The only form of energy conversion (from chemical energy to heat and light)...
Was the Atomic Bomb an Effective Usage of Strategic Bombing? On August 14, 1945, after the atomic bombing, Japan surrendered to the Allied states in World War II. To this day, there are arguments as to whether the usage of the atomic bombs was necessary...
Acceleration experimented with the velocity and time of a falling object to produce a reasonable calculation for the acceleration due to gravity of Earth. The experiment was divided into parts, each with a specific procedure to determine the acceleration due to gravity. Both parts, however,...
Introduction Gravity is the force that attracts a body towards the center of the earth; a common example of gravity taking place is a falling object. When toast slides off a table, it is observed to land jelly side down frequently. As the toast is...
Apparent Weightlessness A frequent misunderstanding by many people today is that astronauts experience zero gravity especially when referring to astronauts in space. Many believe astronauts are weightless in space and that justifies their ability to float and travel through space. However, physics has proven this...
I think that everyone knows Nobel Prize. Every year, some people are announced as a winner. It has six divisions, Physics, Chemistry, Medicine, Literature, Peace, Economic science. This is most popular prize, but how this was established? What is Nobel? Made-to-order essay as fast as...
Heat treatment could be any one of a variety of controlled heating operations used to change the physical properties of a metal; there are five different types of heating processes. These would be case hardening, normalizing, hardening and tempering. Even though they all differentiate in...
Sonography is beginning to be an important but great source of technology in the medical field. “Sonography is a diagnostic medical procedure that uses high frequency sound waves to produce dynamic visual images of organs, tissues, or blood flow in the body (Society of Diagnostic...
The LEED certifications depend on a 100-point scoring system. In order to attain the lowest level of certification a hotel must meet a minimum of 40 points. Whether you are building a brand new hotel from the ground up or are currently operating a full...
Thermal Conduction Thermal conduction is the transfer of energy arising from temperature differences between adjacent parts of a body. Thermal conductivity is recognised as the exchange of energy between molecules and electrons in the conducting medium. The rate of heat flow in a rod of...
Lactic acid is produced when glucose is broken down and oxidized. During intense exercise when oxygen levels are lower, more lactic acid is made, which produce hydrogen ions and a burning sensation in muscles while they’re active. However, on-going soreness in the days following an...
Why do we choose LED Light Bars? A Led lights are a short either long bunch of huge-brightness Led lights. They give a luminous, extensive and forcing pole of light ahead, behind or to the side. They feed a powerful profit for dark driving or...
Lithium-ion batteries are used everywhere from lighting up our mobile devices to powering our electric cars that we drive. Lithium-ion batteries are the best batteries that we have to this day. These batteries will be the best batteries that we will have for a long...
Imagine a world with no light. We use light in our everyday lives. That’s why the importance of light bulb can not be overestimated. Without it we would would have to use oil lamps and candles, and that would be hard. If we didn’t have...
Last some decades studies shows that rapid research has been done on WEDM in terms of improving performance measures, optimizing the process parameters, monitoring and controlling the sparking process, simplifying the wire design and manufacture, improving the sparking efficiency by different researchers. The desired work...
Static electricity is caused by an imbalance of electric charges inside or on the surface of a material. All physical objects are made up of atoms which contain protons, neutrons and electrons. Protons are positively charged, electrons are negatively charged while neutrons are neutral. Like...
Kinetic Theory is a description of the properties of atomic particles in different states such as solids, liquids, and gas. In the various states, the atoms have a different energy level and the movements of the particles also including the distance. Made-to-order essay as fast...
Pure tones don’t naturally exist but every sound in the world is the sum multiple pure tones at different amplitudes. A music song is played by multiple instruments and singers. All those instruments produce a combination of sinewaves at multiples frequencies and the overall is...
