what is nomenclature ??????
Answers
Answer:
Nomenclature, in biological classification, system of naming organisms. The species to which the organism belongs is indicated by two words, the genus and species names, which are Latinized words derived from various sources. This system, which is called the Linnaean system of binomial nomenclature, was established in the 1750s by Carolus Linnaeus. Subsequent to the work of Linnaeus, a proliferation of binomial names took place as new species were established and higher taxonomic categories were formed, with the result that by the late 19th century there was much confusion in the nomenclature of many groups of organisms. In the 20th century, the establishment of rules by international committees in the fields of zoology, botany, bacteriology, and virology has done much to clarify the situation.
The Conservation of Momentum Principle
The principle of conservation of momentum states that in an isolated system, two objects that collide have the same combined momentum before and after the collision. That is, momentum is not destroyed in the collision, but transferred between the two objects. In an isolated system, momentum is always conserved in a collision. In the example of you catching a baseball, the momentum from the ball is transferred into your hand.
How momentum is transferred depends on the type of collision. There are three types of collisions: elastic, perfectly inelastic, and partially inelastic
