The electrophorus consists of a dielectric plate; it is an electrical insulator and a metal plate with an insulating handle. It works by the dielectric plate being charged through the triboelectric effect by rubbing it with fur or cloth. The dielectric gains create negative charge by rubbing together.

Electric Charge and Electric Field:-> 1. Electric Charge Electric charge is a fundamental property like mass‚ length etc associated with elementary particles for example electron‚ proton and many more. Electric charge is the property responsible for electric forces which acts between nucleus and electron to bind the atom together. Charges are of two kinds (i) negative charge (ii) positive charge Electrons are negatively charged particles and protons‚ of which nucleus is made of‚

In modern society‚ more and more liars

TREATMENT OF CORROSION Regardless of the type of corrosion or the metal involved‚ corrosion treatment requires three basic steps: 1. Remove as much of the corrosion as possible. 2. Neutralize any residual material. 3. Restore the protective surface film. CORROSION REMOVAL As previously discussed‚ the first step in corrosion control must be cleaning the surface. After the surface is completely clean and it is determined that corrosion does exist‚ the damage must be carefully assessed

Plant Pigment Lab Question: What pigments are present in Red Wandering Jews? Background: A leaf is filled with many pigments. The pigments are usually masked by the prevalence of the green chlorophyll. Anothocyanin(red or purple)‚ carotene(orange)‚ and xanthrophyll(yellow) are found in different proportions in different leaves. Leaf pigments can be separated by using paper chromatography. Paper chromatography is a technique that extracts pigments into a paper filter called chromatogram. What are

Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events. Plate tectonics is a relatively new science. It’s partially explained in the sense that we still don’t know fully about how the plates came together‚ what they were before they were the seven continents we know today. We already know‚ or have a theory‚ about what our world was like a long time ago and so if we already know that the plates can pull and push against each other‚ then surely
