Calculate the efficiency of a four wheeled Pulley system if it is used to lift a load of 500N by using an effort of 300N

60%

Explanation:

Efficiency is given by the ratio of effort arm to load arm expressed as a percentage. In this case, the effort is given as 300 N while load is 50 N. The efficiency will be

Efficiency= 60%

scientific laws are the result of testing theories and proving them to be facts.

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
