1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral.
In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions.
Castrol Limited is a British oil company that markets industrial and automotive lubricants, offering a wide range of oil, greases and similar products for most lubrication applications. The company was originally named CC Wakefield; the name Castrol was originally just the brand name for CC Wakefield's motor oils, but the company eventually changed its name to Castrol when the product name became better-known than the original company name.
Since 2000, Castrol Limited has been a subsidiary of BP, which acquired the company for $4.73 billion.
In physics, a fluid is a liquid, gas, or other material that may continuously move and deform (flow) under an applied shear stress, or external force. They have zero shear modulus, or, in simpler terms, are substances which cannot resist any shear force applied to them.
Although the term fluid generally includes both the liquid and gas phases, its definition varies among branches of science. Definitions of solid vary as well, and depending on field, some substances can have both fluid and solid properties. Non-Newtonian fluids like Silly Putty appear to behave similar to a solid when a sudden force is applied. Substances with a very high viscosity such as pitch appear to behave like a solid (see pitch drop experiment) as well. In particle physics, the concept is extended to include fluidic matters other than liquids or gases. A fluid in medicine or biology refers to any liquid constituent of the body (body fluid), whereas "liquid" is not used in this sense. Sometimes liquids given for fluid replacement, either by drinking or by injection, are also called fluids (e.g. "drink plenty of fluids"). In hydraulics, fluid is a term which refers to liquids with certain properties, and is broader than (hydraulic) oils.
Mercon represents a series of technical standards for automatic transmission fluid, developed and trademarked by Ford Motor Company. This designation serves as a mark of quality that Ford has established for fluids used in automatic transmissions. The Mercon name, which has evolved into a brand, is licensed by Ford to various manufacturers. These companies are authorized to produce the fluid according to Ford's specifications and market it under their own brand names.
The specifications outlined under the Mercon label cover various aspects such as viscosity, friction characteristics, and thermal stability, which are essential for the transmission fluid to perform under a wide range of operating conditions. This careful regulation ensures that all licensed Mercon fluids provide consistent quality and performance, giving consumers confidence in their use of aftermarket products.
The quart (symbol: qt) is a unit of volume equal to a quarter of a gallon. Three kinds of quarts are currently used: the liquid quart and dry quart of the US customary system and the imperial quart of the British imperial system. All are roughly equal to one liter. It is divided into two pints or (in the US) four cups. Historically, the exact size of the quart has varied with the different values of gallons over time and in reference to different commodities.
V, or v, is the twenty-second letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is vee (pronounced ), plural vees.
