A boy pushes a 35 kg table with rubber padding under the legs across a dry concrete floor. How much force does the boy need to continue
applying to keep pushing the table? The kinetic friction coefficient is 0.8.
0 272 N
429 N
28 N

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

snell's law

refractve index = sin incidence / sin refraction
