Electric and magnetic fields in matter

The Atomic Theory states that all matter is composed of discrete units called atoms. The Atomic Theory started in about 400 BCE with a scientist by the name of Democritus. Democritus proposed the idea of the existence of an ultimate particle. He called this particle atomos when he was describing it, because the particle was too small to cut. Next, we get to Leucippus. Leucippus was the man who founded atomism, which is a theoretical approach that states nature consists of two principles, which…

change was in the nineteen-twenties by a man named Lloyd Loar, which at the time worked for a notable guitar producer called Gibson. He added electrostatic pickups on a small handheld bass; but, no sound could really be produced since the first electric amp we created in the nineteen-forties. The nineteen-thirties were an odd time for a bass guitar.…

Research for AS91172 Billy Barrow From Thompson 's Model to Rutherford 's Model By the time that Joseph John Thompson confirmed that Cathode Rays were made up of negatively charged particles in 1897. The groundwork for the idea of the atom had been in the works for many years. From ideas from Leucippus and Democritus from ancient Greece who first proposed the idea of 'atomos ' meaning “inadvisable”. This idea of the smallest thing went on largely ignored in favour of the ideas of Aristotle,…

Physical properties are used to observe and describe the matter that they are testing for. Properties; • Density – Density is a figure that tells us how many kilograms of a uniform substance is contained in a volume of 1m³. Density is also defined as the ratio of mass to the volume and is given the symbol ρ…

Sensing, this type can be classified as a passive system where it depends on the reflected energy from the sun. It helps in understanding of land surface conditions such as vegetation, rivers, lakes, and urban areas distribution. Also it can be used in field of water quality monitoring. 2- Thermal Infrared Remote Sensing, this type classified as a passive system where it depends on collecting the thermal infrared rays radiated from land surface heated by sunlight. It can be used in identifying…

Contraband control becomes more difficult as inmates find new, innovative ways to exploit the system. Staff members in prisons are required to think one step ahead to prevent any risk of losing their lives. Contraband, defined by The National Institute of Justice, are items illegally smuggled into correctional facilities such as weapons, drugs or anything prohibited in the monitored area including cell phones. One of the items smuggled most into facilities are cell phones. “In 2008,…

efficiency to the draft flame. You can really see the lamp technology explode when each civilization combines other technology to achieve a new type of fire lamp. In 1841 Arc-lighting, 1854 incandescent lamp by passing an electric current through a carbonized bamboo filament, 1867 coated electric discharge tubes with luminescent materials, a process that was further developed in later fluorescent lamps. Now keep in mind this technology is adapting, and modifying as each person; each civilization…

Over 104 years ago, on August 7th, 1912, an Austrian scientist named Victor Hess changed the Astronomy and Physics world forever when he discovered cosmic rays through a strange experiment that took place in a hot air balloon. Cosmic rays are high-energy, subatomic particles that appear outside the Earth’s atmosphere. These rays are known to strike to down on Earth, which may seem dangerous but even very energetic primary rays crash into the Earth’s atmosphere and they basically never make it to…

nature of electromagnetic radiation is not clearly known, as it has the development of quantum mechanism in the first quarter of twentieth century. Wave properties of electromagnetic radiation Electromagnetic radiation consist of oscillating magnetic and electric…

They claim barrel horses are hauled for extensive amount of hours, sore, young barrel horses are rode before they should be and nothing matters other than a time. Many highly disagree with all this being said. Barrel horses are fed the best kind of sweet feed being made, with supplements that help horses with sore muscles, hock problems or anything else that may hurt. Horses are hauled in…
