A sled with a mass of 40kg is pulled along flat, snow-covered ground. The static friction coefficient is 0.40, and the kinetic friction coefficient is 0.20. A. What does the sled weigh?
B. What force will be needed to start the sled moving?
C. What force is needed to keep the sled moving at a constant velocity?
D. Once moving, what total force must be applied to the sled to accelerate it at 3.0m/s^2?

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

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
