Objective: The purpose of this lab is to demonstrate that there is a linear relationship between the number of molecules that can absorb light present in a solution and the amount of light absorbed by a solution. This lab should prove that Beer’s law and the equation A=a x b x c‚ is a linear relationship. Procedure: The only deviations in the lab procedure was that the stock solution was made before arrival to the lab with 0.570 g of KMnO4 in 0.500 L. The diluted solutions and the

Abdullah Buchh Grade 4 Isaac Newton Background Information Isaac Newton was born On December 25th 1642 in the small village of Wools Thorpe‚ in Lincolnshire‚ England. His father‚ Robert‚ died three months before he was born. Isaac’s mother remarried a wealthy clergyman‚ Reverend Barnabus Smith‚ who wanted Isaac to be educated. He was sent to King’s School in Gratham. There is very little known about his school days. In 1660‚ Isaac went to Trinity College in Cambridge. There he scribbled

Introduction! ! The Michelson Interferometer is commonly used to determine the wavelength of light or measure very small distances. It was invented by Albert Abraham Michelson and is commonly used in optical interferometry‚ a branch of physics involving a family of techniques one could use to extract information about waves by superimposing them. ! ! The original application of the Michelson Interferometer was to the famous Michelson-Morley experiment in 1887. Prior to Einstein’s

Isaac Newton is considered to be one of the greatest theoretical and scientific minds of our world. The year that Galileo died‚ Isaac newton was born in Woolsthorpe Manor‚ his family’s estate‚ in Lincolnshire‚ England on January 4th‚ 1643 as a premature baby. Isaac was very frail and sickly. The women and housemaids didn’t even hurry to bring medicine to help him because nobody expected him to survive. But miraculously he did survive. Isaac’s father‚ Isaac Newton Sr.‚ had died few months before his

Ethanoic acid is a weak acids. That means that its solution contains a high proportion of molecules that haven’t split into ions. For all the reactions which give off hydrogen‚ the same ionic equation applies - whether the acid is strong or weak: Mg(s) + 2H+(aq) Mg2+(aq) + H2(g) The key factors to vary‚ control or take into account The amount of heat given out will depend on the mass of magnesium I use - the more magnesium I use‚ the more of the above reaction happens. But because I am going to

the water can therefore be determined to allow for the calculation of Reynolds’ number. A dye injection system is installed on top of the header tank so that flow pattern in the pipe can be visualised. In this experiment‚ we fix the time which is 5 second to collect the amount of the water. At the same time‚ we also observe the characteristic of the flow whether is it laminar‚ transition and turbulent flow. THEORY: Reynolds number basically determines the transition of fluid flow form laminar flow

Taxation Law Question: What is the “first strand” of the decision in FC of T v The Myer Emporium Ltd 87 ATC 4363? Did the courts apply the first strand in any of the following cases: FC of T v Cooling 90 ATC 4472‚ Westfield Ltd v FC of T 91 ATC 4234‚ Henry Jones (IXL) Ltd v FC of T 91 ATC 4663 and SP Investments Pty Ltd v FC of T 93 ATC 4170? If the first strand did not apply in some of these cases but amounts were nevertheless assessable‚ on what basis was this so? Answer: Introduction

Descartes and Newton The old saying "great minds think alike" is not just an old saying. It was at least partially true concerning the minds of Rene Descartes and Isaac Newton. The significant scientific contributions of each man share some common concepts and methodologies‚ but they generally explored different topics of research. Each scientist based his beliefs on different mind sets. The similarities between Newton and Descartes are found deep in the foundations of their beliefs and
