A student uses a pencil as a lever to launch a piece of trash into the trashcan. If the student positions a marker as the fulcrum just 2.8 cm from where she applies effort, and 7 cm from the piece of trash to the fulcrum, what is the mechanical advantage the lever gives?

Formulas:
Mechanical advantage = effort distance/resistance distance
Mechanical advantage = resistance force/effort force
Work = force × distance

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
