In 1873, a committee of the British Association for the Advancement of Science, including physicists James Clerk Maxwell and William Thomson recommended the general adoption of centimetre, gram and second as fundamental units, and to express all derived electromagnetic units in these fundamental units, using the prefix … What unitRead More →
The dielectric constant of a substance can be defined as the ratio of the permittivity of the substance to the permittivity of the free space. K = ε/ε0. As it is the ratio of two like entities, it is a unitless, dimensionless quantity. What is dielectric and dielectric constant &Read More →
Generally, permittivity of free space is represented by . Here the options are in the terms of charge, force and length. To find that unit, we can use Coulomb’s law. What is permeability unit? In electromagnetism, permeability is the measure of magnetization that a material obtains in response to anRead More →
Formal names of military units, including armies, navies, air forces, fleets, regiments, battalions, companies, corps, and so forth, are proper names and should be capitalized. … Unofficial but well-known names should also be capitalized (the Green Berets, the Guard). Is servicemember one word or two? Note that the word Servicemembers’Read More →
Level of Force. Does your machine require a unit that provides a consistent force, for larger-scale tasks? … Size Matters. The machine’s size is also as important as it’s functionality, as the power unit can be selected based on this. … Flow Rate. … Outlet and Inlet Hoses. How isRead More →
The thermal conductivity coefficient k is a material parameter depending on temperature, physical properties of the material, water content, and the pressure on the material . The coefficient k is measured in watts per meter Kelvin (or degree) (W/mK). What is a high thermal conductivity? Thermal conductivity, frequently represented byRead More →
A nanometer is a unit of measurement length in the metric system which is one billionth of the standard unit of measurement “meter”. It is denoted by ‘nm’. … Hence the relation between a nanometer and an angstrom is that one nanometer is equal to ten times of an angstrom.Read More →
What type of serological testing does the blood bank technologist perform when determining the blood group of a patient? B. Phenotyping, or the physical expression of a genotype, is the type of testing routinely performed in the blood bank. An individual, for example, may have the AO genotype but phenotypesRead More →
Why do chillers using low-pressure refrigerants require purge units? These systems require the removal of contaminated refrigerant. These systems operate below atmospheric pressure. Purge units remove refrigerant from the oil sump. What is the purpose of the purge unit? A purge unit is typically used to remove air and otherRead More →
Here are the steps for identifying the coordination number of a coordination compound. Identify the central atom in the chemical formula. … Locate the atom, molecule, or ion nearest the central metal atom. … Add the number of atoms of the nearest atom/molecule/ions. … Find the total number of nearestRead More →
