Write the equation that links extension, force and the spring constant.

That equation is called Hooke law, and it is:

F = -k•x

Where F represent the force, k is the spring constant, and x is the displacement (extension) of the spring

F = -k × x

Explanation:

As an equation, F = kx, where F is the force we apply, k is the spring constant, and x is the extension of the material (typically in meters).

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
