Suppose a physics instructor seated himself at rest on a low-friction "piano stool" and held a spinning bike wheel with its angular velocity vector initially horizontal. Suppose the instructor then turned the bike wheel so that its angular velocity vector pointed vertically downward. When this turn was completed, the instructor would be spinning rapidly on the stool. What would be the final, total angular momentum of the system of instructor plus bike wheel, projected along the vertical axis, the only axis along which the system can spin?

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
