Ac Hpat Physics Exam Solved 100% Correct!!

Efficiency {Ans: · Efficiency is a measure of how much work or energy is conserved in a process. In many processes, work or energy is lost, for example as waste heat or vibration. The efficiency is the energy output, divided by the energy input, and expressed as a percentage. A perfect process would have an efficiency of 100%.}Gravitational force {Ans: · The gravitational force is a force that attracts any two objects with mass. ... In fact, every object, including you, is pulling on every other object in the entire universe! This is called Newton's Universal Law of Gravitation.}kinetic friction {Ans: · Kinetic friction magnitude is directly proportional to the normal force magnitude and the roughness between the sliding surfaces. Static friction magnitude is directly proportional to the normal force magnitude and the roughness between the sliding surfaces.}Static pressure {Ans: · Static pressure is one of the most important factors in HVAC design. Simply put, static pressure refers to the resistance to airflow in a heating and cooling system's components and duct work. The push of the air must be greater than the resistance to the flow or no air will circulate through the ducts}Boyles Law
