A Carnot engine is reversible and has the maximum possible efficiency, given by the following equations. i>Now students who are prepping for exams, preparing to study new material, or who just need a refresher can have a concise, easy-to-understand review guide that covers an entire course by concentrating solely on the most important concepts.

Tracks a typical undergraduate optics course Detailed explanations of concepts and summaries of equations Valuable tips for study from college professors If you're taking an optics course for your major in physics or engineering, let Optics For Dummies shed light on the subject and help you succeed!

Physics Essentials For Dummies(9781119590286) was previously published asPhysics Essentials For Dummies (9780470618417). As you study physics, you will start to see, whoa, most of what we consider to be reality, our current understanding is based on these forces, but what are these forces?

Maths is the theory behind the idea in that maths is always right or wrong and it can be demonstrated to be, we don't need to know the whole universe inside out to know an equation is right or wrong.The amount of work performed in proportion to the amount of heat extracted from the heat source is the efficiency of the engine. Frictional forces, F_F, are in proportion to the normal force between the materials, F_N, with a coefficient of friction, μ. And even these things that we think are solid, when we go down to the atomic level, we see it's mostly empty space and it's really just the interaction of forces that make us think that something is solid or there or tangible is some way. png\" width=\"141\" height=\"24\" />\n
