Molecular Mass Molecular mass is the sum of the atomic masses of all the atoms present in one molecule of a molecular compound. Simple…
Cloud Computing refers to the use of hosted services such as servers, data storage, databases, networking, and software over the Internet, maintained by a…
Shear modulus is the ratio of shear stress to shear strain. It measures resistance to a change in shape caused by tangential force.
Brahmagupta (about 628 AD) wrote rules for the symbol of nothingness, including how to treat it in calculation. Al-Khwarizmi's sifr gave European languages the…
Macroscopic Events: Phenomena that can be observed with the naked eye without considering the individual particles or molecules involved in the process.…
(a+b)n = sumr=0n nCr an-r br . There are n+1 terms. Coefficients are a row of Pascal's triangle. Meaning: you expand by choosing b from r of the n…
Proteins are very important molecules in our cells. They are involved in virtually all cell functions. Each protein within the body has a specific function.…
The half-life of a radioactive substance is the time required for the number of undecayed nuclei, or equivalently its activity, to fall to half its initial…
Efficiency is the ratio of useful work output to the total work input, or the ratio of useful energy output to the total energy input. It is a measure of…
Hepatitis: Hepatitis is generally characterized as inflammation of the liver including other symptoms. It is generally caused by viral infection or rarely…
A null model: if no selection, no mutation, no migration, no chance wobble, and random mating, allele frequencies stay put. p + q = 1. p^2 + 2pq + q^2 = 1 for…
Use less fossil energy, efficiency, trees as a slogan. Nuclear and solar appear in the energy chapter. No weather-weapon or SRM how-to. Mitigation slogans:…
Fitness here means relative reproductive success, not gym fitness. Types named: directional (one extreme), stabilising (middle), disruptive (both extremes).…
This topic compares the electrical behaviour of conductors and insulators.
Deoxyribose. Phosphodiester named as the link. 5' phosphate end, 3' OH end. Chargaff: A=T, G=C in amounts. Rosalind Franklin's pattern named as evidence in the…
Diamond and CO2 are inorganic in the school split. Organic: carbon compounds of living-style chains, with named exceptions. Crude oil is a mixture of…
Mass Spectrometry: An analytical technique used to determine the molecular composition and structure of a sample by measuring the mass-to-charge ratio…
Acidified silver nitrate gives white, cream, or yellow precipitates with chloride, bromide, or iodide ions.
Inductive Reasoning: A type of reasoning in which generalized conclusions are drawn from specific observations. Al-Ghazali's Challenge to…
An atomic spectrum is the pattern of discrete wavelengths or frequencies emitted or absorbed by atoms because of transitions between quantized energy…
Embedded Systems are small electronic devices which are a combination of hardware and firmware. They have a microcontroller or microprocessor that controls the…
Tension, gravity and the normal force can each act as the centripetal force in suitable situations.
Bases are substances that: · Taste bitter · Feel slippery in aqueous solution · Turn red litmus blue · Neutralize acids to form salt and…
