I. Temperature Measurement 1. A thermometric property is a physical property that changes in a known way with temperature‚ and can therefore be used to measure temperature. The substance used as a thermometer must have a property that varies proportionally / linearly with temperature. [ In other words: When objects are heated or cooled‚ their temperatures change‚ along with some of their properties‚ these properties are known as Thermometric Properties.] Two commonly used thermometric properties

UNIT 1 Modern Physics 1.1 CLASSICAL PHYSICS Newtons laws of motion are the basis of the most elementary principles of classical physics. Equations based on these laws are the simplest and they are suitable for solution of simple dynamical problems‚ such as the motion of macroscopic bodies‚ Lagranges equations‚ Hamiltons equations and Hamiltons principle are also fundamental principles of classical mechanics‚ because they are consistent with each other and with Newtons laws of

Usually the power of the present societies is tripartite. The power is divided into an executive‚ a legislative and a judicative part. As though is it also in the science fiction film Equilibrium written and directed by Kurt Wimmer. After World War III only one civilised stronghold is left‚ the city-state Libria. The city-state contains the same structure of state as we know it today from totalitarian states. However the power of state is tripartite and Preston is part of the executive apparatus

it gets crisp in the fall‚” (Fitzgerald). In “The Great Gatsby” there are so many provocative and cryptic characters that have secrets to hide. A static character is a character that stays the same from beginning to end which in this case are many from this particular book. Tom Buchanan and Jordan Baker are two characters from this story that are “static characters”. A character that shows a lot of change in their personality is a dynamic character and in this book his name was Nick Carraway. To

Introduction of Physics: Physics ("knowledge of nature") is the science concerned with the discovery and understanding of the most basic fundamental laws of the universe that control the way everything in the world around us behaves. Discoveries in basic physics have important ramifications for all of science. Physics attempts to describe the natural world by the application of logic scientific methods‚ including modeling by theoreticians. As a core scientific discipline‚ physics is concerned with
