He called them 'vitreous' and 'resinous' because they were created when amber (tree resin) was rubbed with fur and glass was rubbed with silk. This can have very serious consequences and even fatalities.ДЄs early as in 1729, a French scientist Charles du Fay suggested the existence of charges of different types and proved this experimentally. The electric charge stored on the clothes or the shoes when the fabrics and materials are rubbed against each other and other surfaces can destroy microchips.ДЄntistatic properties of fabrics and materials for shoes are also extremely important in the oil and gas industry because even a small spark can cause an explosion or a fire on the premises. We should note that the antistatic properties of clothes and shoes are very important in some clean industrial facilities, for example in production facilities that make microelectronic products.

This property, along with electric resistivity is a characteristic of anti-static properties. In order to control the antistatic properties of polymers, various methods of measuring the surface charge density are used. They use various ways to decrease static electricity, but the use of more advanced technologies increases production costs. There are different technologies that aim at producing fabrics with antistatic qualities. If you ever took off your synthetic sweater in a dark room, you would have noticed the sparks and heard the characteristic crackling sound of the electric charge.Дoctors are wary of this property of synthetic materials and recommend using more natural fabrics with as little synthetic additions as possible, at least for the undergarments. They are quick to gain static electricity, which we can literally feel on our skin.

Unfortunately, not everything is perfect with these synthetic materials. Synthetic fabrics have many other benefits, including durability, resistance to liquid, and anti-wrinkling properties among others. Indeed, thanks to these materials we were able to fully answer all of our needs for clothing, from lacy tights to light and warm sweaters and comfortable stylish jackets with synthetic insulation usually made of thin polyester fibers. Ever since viscose and nylon were invented, our chemical industry is generous in supplying us with various synthetic fabrics that we cannot imagine living without.

We live in an era of synthesized materials. The horizontal axis is the ratio of the distance to the rod divided by the length of the rod.A static discharge between a finger and a metal door Number of pieces (for the numerical calculation) = 100.I want to plot the magnitude of the electric field as a distance from the rod for all three methods (the two equations and the numerical method). The second formula is an approximation if the length of the rod is long compared to the distance from the rod. Skipping the derivation, I have two expressions for the magnitude of the electric field along an axis perpendicular to the center of the rod. This is a region that I can also calculate the electric field using calculus such that I can see how well the two methods agree. In order to determine the accuracy of this numerical model, I need to calculate the electric field along an axis perpendicular to the rod and in the center of the rod. That looks very pretty, but it's not that useful. However, I will show you what it looks like. There are probably many introductory physics classes that use this problem as part of a homework assignment or something. I know, that sort of stinks - but that's the way things are going to be.
