Amwoga Khalwale What Is A Solenoid? A solenoid is a long coil of wire wrapped in many turn, when a current passes through it, it creates a nearly uniform magnetic field inside. Solenoids can convert electric current to mechanical action and so are very commonly used as switches. The magnetic field within a solenoid depends upon the … Read more
What Is Enantiomers? An Enantiomer is one of the two molecules (stereoisomers) that are mirror images of each other and are non-superposable. Enantiomers have identical chemical and physical properties such as boiling point, melting point and spectroscopic features except for their ability to rotate plane-polarized by equal amounts but in opposite directions. Enantiomers interact differently … Read more
Cryptogams A cryptogam is a plant that reproduces by spores without flowers or seeds. The best-known groups of cryptogams are algae, lichens, Hornworts, Liverworts, mosses and ferns. It also includes non-photosynthetic organisms traditionally classified as plants, such as fungi, slime molds and bacteria. Characteristics Of Cryptogams Phanerogams Phanerogams are plants comprising those having reproductive organs, … Read more
Stereoisomers are pairs of compounds that have the same chemical formula and the same atom connectivity, but they differ in their three-dimensional orientation. Monosaccharide like glucose, fructose, mannose and galactose can show different isomerism. For example glucose and fructose are functional isomers of each other as glucose contains aldehyde group and fructose contains ketonic group … Read more
Permanent magnets and electromagnets are two main types of magnets. A permanent magnet is called a permanent magnet because of ability to generate and retain its own persistent magnetic field. An electromagnet on the other hand is made from a coil of wire wrapped around a ferrous core and requires an electric current to generate … Read more
What Is Tension? Tension is described as the pulling force transmitted axially by the means of a string, a cable, chain or similar one-dimensional continuous object or by each end of a rod, truss member or similar three-dimensional object; tension might also be described as action-reaction pair of forces acting at each end of said … Read more
Job order costing or job costing is a system for assigning and accumulating manufacturing costs of an individual unit of output. The job order costing system requires a separate job cost record which reports each item’s direct materials and director labor that were used and assigned amount of manufacturing overhead. The record may also show … Read more
In digital logic and computing, a counter is a device which stores and sometimes displays the number of times a particular event or process has occurred, often in relation to a clock. The most common type is a sequential digital logic circuit with an input line referred to as the clock and multiple output lines. … Read more
What Is A Mineral? A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form and physical properties. Minerals also have a distinct shape and can easily be identified solely by their form and color patterns. Other distinctive properties of minerals include hardness, specific gravity, … Read more
Zucchini and courgette are actually the same vegetable, known by different names in different parts of the world. The term “zucchini” is commonly used in the United States, while “Courgette” is the term used in the United Kingdom, parts of Europe and some other English-speaking countries. In other words, there are no inherent differences between … Read more
