Calculate the work done by a 4.2 N force pushing a 450. g sandwich across a table 0.8 m wide.

3.36 Joules

Explanation:

Work done= Force × distance

F=4.2 N

distance= 0.8 m

work done= 4.2 × 0.8

work done= 3.36 Joules

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
