If a spring stores 20 j of energy when it's compressed by 0.4 m what is the spring constant of the spring

250 N/m

Explanation:

Spring's Potensial Energi

SE = ½ c ∆x²

c = spring's contants

20 = ½ . c . 0,4²

20 . 2 = 0,16c

c = 40/0,16 = 250 N/m

ice to water 1 water to vapour 2 latent heat

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
