In electricity generation, an electric generator is a device that converts mechanical energy to electrical energy. A generator forces electric charge (usually carried by electrons) to flow through an external electrical circuit. It is analogous to a water pump, which causes water to flow (but …
Solenoids Permanent Magnet- Magnetic Field. http://www.diracdelta.co.uk/science/source/m/a/magnetic%20field/source.html Magnets have two poles called North and South. Similar (like) magnetic poles repel. Unlike magnetic poles attract. A magnet attracts a piece of iron. The most important of the two properties of attraction and repulsion is repulsion. The only …
Descanter’s theories of light and vision were central components of his natural philosophy, closely linked to his cosmology, physics, theory of matter, and theory of perception. Descartes replaced traditional explanations of natural phenomena with explanations hidden under terms of matter and motion. By eliminating these …
Nuclear Power is produced when a nucleus absorbs a neutron and splits into two lighter nuclei. This releases enormous amounts of energy which in turn produces heat. In fact the Uranium, which is the most common element used to produce nuclear power today, has an …
Abstract In this paper, a elaborate survey on the Model Reference Adaptive Controller ( MRAC ) using the reactive power is presented for the on-line appraisal of rotor opposition to keep proper flux orientation in an Indirect Vector Controlled Induction Motor Drive. Choice of reactive …
This larger surface area-to- illume ratio allows for a sharper more accurate melting point. 4. Approximately 20 crystals should be loaded onto the coveralls to ensure that the sample is heated evenly. 5. The temperature of the stage should be ICC below the expected melting …
Chromatography is a physical method used in lab for separation of a mixture of chemical substances into its individual components, so that the individual components can be thoroughly analyzed. it has numerous applications in biological and chemical fields. it is widely used in biochemical research …
Metals are electropositive chemical elements that are characterised by the following qualities: ductility, malleability, luster, opacity, and conductance of heat and electricity. They can replace the hydrogen of an acid and form bases with hydroxyl radicals. Density is defined as a material’s mass divided by …

Radiotherapy intervention has a important and critical axial rotation in the intervention of cancerous diseases. Different types of techniques were used for this intent. In past, conventional radiation therapy technique was used. But it did non efficaciously used for intervention of tumours located in sensitive …
Why Save Electricity? With the rising costs and shrinking economy more and more people are acting responsible and seacrhing for reasonable ways to save electricity. The other reason apart from these are that saving electricty will bring down your electicity bills, save you money and …
Since its find in 1960s by the Nipponese, atomic power had been used as one of the chief energy to bring forth power in more than 30 states in this universe. This natural resource is known as the safest energy-dense of all natural resources, where …
In today’s world, cell phones are part of a life. As the technology improves more and more people are buying cell phones. Many new cell phones are like a small computer, as they have a picture and video camera, web browsing, music player, internal storage, …
The novel Kindred by Octavia Butler is a story based upon time travel. The protagonist, Dana, travels back in time to Maryland around the early 1800’s when slavery was very prevalent. Dana makes it clear that they were originally observing everything. She states on page …
Each individual has unique memory for oneself shared with no one else in the world. Such memory makes one different from others. Therefore I am curious to know what memory is. Right now I am Just a bundle of “memories” in my mind and body. …
In this physics coursework, I have been asked to carry out research of my selection and to develop it. I have selected to research the life cycle of a star, and I would conduct this by gathering the necessary information in a form of a …
“The road to success is always under construction” (Tomlin qtd. in “Lily”). Civil engineering has been around for centuries advancing its use throughout history shaping our society as a whole with its creative style of education, skills, and experiences. Analysis of civil engineer work ethics …
Low pressure systems form at mid latitude temperate zones as a result of the convergence of warm and cold air masses. Low pressure systems generally form over the polar front where the polar maritime air (a cold air mass) and tropical maritime air (a warm …
Crystal structure, optical and electrical characteristics of rutile TiO2- based photoanodes doped with GeO2 The effect of germanium dioxide GeO2 doping on dye-sensitized solar cells (DSSCs) TiO2 nanocrystallites photoanodes with different concentrations with composition (TiO2-(GeO2)x: 0 * x 0.3 wt%) has been studied. The samples …
5. Wien’s law explains that objects of different temperatures emit spectra that peak at different wavelengths. Hotter objects emit shorter wavelengths, thus appearing bluer, whilst colder objects emit longer wavelengths, appearing redder. A star’s surface temperature can be deciphered using this method by seeing its …
Lens Antenna an antenna whose directivity pattern is a result of the difference between the phase velocity of propagation of an electromagnetic wave in air and that in the lens material. Lens antennas are used in radar and metering equipment that operates in the centimeter …
IntroductionContinuous casting of steel is a procedure with many factors involved. If any of those factors are non controlled it can hold inauspicious effects to both the steel produced and the equipment bring forthing it. This paper will briefly travel over the demands and equipment …

Magnitude
In physics, magnitude is described in simple words as 'distance or quantity'. It shows the direction or size that is absolute or relative in which an object moves in the sense of motion. It is used to describe the size or extent of something. Generally, in physics, magnitude relates to distance or quantity.
Equilibrium
equilibrium, in physics, the condition of a system when neither its state of motion nor its internal energy state tends to change with time.
