Pipetting‚ weighing‚ accuracy and plotting Introduction The aim of this experiment was to determine the density of water and‚ of unknown solutions‚ by being as accurate as possible‚ by pipetting and weighing the solutions. Density if defined as “The mass per unit volume of substance; common unitg cm-3” (Lewis. R and Evans. W.‚ 2011). As the density is an intensive property of all matter it depends on temperature and pressure. “The density of a mixture may also depend on its composition” (Nedelsky

Unlike geometry‚ algebra was not developed in Europe. Algebra was actually discovered (or developed) in the Arab countries along side geometry. Many mathematicians worked and developed the system of math to be known as the algebra of today. European countries did not obtain information on algebra until relatively later years of the 12th century. After algebra was discovered in Europe‚ mathematicians put the information to use in very remarkable ways. Also‚ algebraic and geometric ways of thinking

Introduction: A deep foundation is a type of foundation distinguished from shallow foundations by the depth they are embedded into the ground. There are many reasons a geotechnical engineer would recommend a deep foundation over a shallow foundation‚ but some of the common reasons are very large design loads‚ a poor soil at shallow depth‚ or site constraints (like property lines). There are different terms used to describe different types of deep foundations including the pile (which is analogous

The movie was so popular because of its mixture of historical accuracy and added drama to make the movie a thriller. This paper will go into detail about the accuracies and inaccuracies of the film Munich. This paper will show one example of how “based on true events” doesn’t necessarily mean everything in the movie is accurate. Munich is an on screen adaptation
