Circuit Theory
The use of a combination of the two models helps achieve low and high frequency paths without having to bear the losses associated with convectional power-splitter circuits.To understand how the circuit operates we can evaluate the behavior of the constituent components. One of these components is the capacitor which is a passive basic circuit element that stores electric energy. It has a current-voltage relationship given by, . Voltage across it doesn’t change instantaneously and when there

How do airplanes fly
As mentioned before, control forms the most crucial factor when analyzing the flying process and though the Wright brothers were not the first to be involved in the experimental aircraft, still they have the honor to be the first people to invent control necessary for managing the aircraft balance. The concept of fixed-wing powered flight was totally impossible before the Wright brothers invented aircraft controls and made the first fully controlled, balanced, and powered flight, thus bringing

Earth Science Geology
They are also helpful in discovering climate change and contribute to the ideas of causes of climate change. In addition, geologists study the earth and the way it came into being (Monroe, 2012).Through studying natural hazards, it is possible to develop early warning systems of the disasters that may have been predicted. Climate change being a core issue currently, then geological studies helps the whole world to know some of the causes such as burning of fossil fuels and the use of CFCs.

X-ray Fluorescence
This phenomenon also applies in the quantitative analysis of elements through the production of optical emission spectra.With characteristic X-rays resulting from transition between the energy levels in an atom, the electrons that transition from energy level Ei to Ej would emit X-rays with energy Ex = Ei – Ej. With each element having unique atomic energy level set, a unique X-rays set would be emitted characteristic of the element (Sharma 526). Considering Bohr’s atomic model (see fig.

Geothermal Power Production and Direct Use
Loss of efficiency is lost during processing of energy, for example geothermal electric production undergoes so many processes that reduce the energy production efficiency. However, on the part of direct use of thermal power, these numerous processes are not involved and hence energy efficiency is not lowered.The site of the geothermal production system should contain extensive low permeability rocks that achieve the right temperatures ideal for geothermal power generation. To provide thermal

Equations of Motion
The simple pendulum was set up. The setup was made up of three regions. The centre was the pendulum. The length of the pendulum was chosen for the pendulum by using the slider on the left side of the screen. This value was recorded in the data table. The amplitude was raised to about 20 degrees. This value was equally recorded in the data table. The start animation button was clicked, and when the pendulum passed its lowest point, the timer was started. The time taken for the pendulum to

Wealth and Geopolitics of Sediments (Past, Present, Future)
It is widely believed that the continued mining and use of coal power in China may significantly result in increased carbon emissions and consequently undermine international initiatives designed to decrease Carbon emissions such as the Kyoto protocol. This paper critically explores the formation of the China Coal deposits, the geopolitics of its past and present utilization as well as the potential environmental impacts.Coal is a combustible form of brownish black sedimentary organic rock that

The creation of the Universe
Finally, the fact that the far-away objects move away from the observer at a speed greater than the speed of the light was evidence that the universe is expanding. However, this observational verification was not in existence by 1915 when Einstein was establishing his theory. He added the “cosmopolitan constant” to neutralize the spreading out of the universe (Krauss, 2012). This theory assumed that then universe must have come into existence from a period of elevated bend in the ancient

The hanging mass is attached at the end of the string to provide tension. When a horizontal pick is used to pluck the string just at the pulley, a pulse is created in the string and travels along it in form of a disturbance. A timer is started by the pulse created in the wire by the plucking effect. The timer continues recording the time until the traveling pulse reaches the sensor, which stops it. When the mass attached to the other end of the string is changed, the time taken by the pulse to

Low level wastes can comprise 90% volume but only 1% of the radioactivity of all radioactive waste. Intermediate level waste contains higher amounts of radioactivity, mainly comprises resins chemical sludge, metal fuel claddings and contaminated materials from reactor decommissioning. Some of the intermediate level wastes require shielding.7% of the intermediate level waste contains an estimate 4% of radioactivity (Nikitin, Andrews & Holt, 2009, pp112- 167).

Debate Question
As Barney Frank said, space exploration is of immense significance. However, sending men to the Mars and back to Earth will cost Americans hundreds of billions of dollars yet bear little worth. In 2013, the government spent over 4 trillion dollars. While only 0.5% of this went into funding NASA, it disturbs the mind why so much money should be used on exploration of the space while a little less than that could influence so positively in making the lives of people better on earth.

How are isotopes used to interpret the climatic history of Sisimiut in Southwest Greenland
For example, isotopic enrichment in smaller lakes has been experienced in the relatively dry years, which buffer the larger lakes in their response to short-term changes (Erbs-Hansen, Knudsen, Lykke-Andersen, Underbjerg, Sha,2013). The inland lakes have δ13C contributions from the exchange with isotope-rich atmospheric carbon dioxide and organic carbon. δ13C has been depleted in the small coastal lakes due to organic materials. This study indicates the importance incorporating local hydrogen
