In the text, we said that the five-times ionized oxygen (ovi) seen in hot gas must have been produced by supernova shocks that heated the gas to millions of degrees, and not by starlight, the way h ii is produced. producing ovi by light requires wavelengths shorter than 10.9 nm. the hottest observed stars have surface temperatures of about 50,000 k. could they produce ovi?

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
