Section 7D Date Work Performed: October 18th 2012 Date Report submitted: October 25th 2012 Abstract Absorption spectroscopy is a practical way to find what the light absorption of a substance is‚ and whit this data combining the Beer’s law equation you can determine the concentration of different things in a solution‚ in this case using a orange Gatorade looking the concentration of its dye which is yellow dye #6 and what amount of this Gatorade sample is needed to kill someone. The outcomes

The outcome from this lab is to be able to differentiate when to use ohmmeter and voltmeter for the individual circuit. II. Theory Ohm’s Law states that the electric current through a material is directly proportional to the voltage across a piece of material (such as wire) while the resistance is held

Research Paper on Pascal’s Law Blaise Pascal’s findings and contributions to the behavior of fluid in an enclosed space have been an invaluable and important concept in fluid mechanics and its applications especially in the automotive industry‚ mechanical engineering‚ and hydraulics. Pascal’s law or the principle of transmission of fluid-pressure that was proposed by Blaise Pascal. According to Bloomfield‚ the law is a principle in fluid mechanics that states that for a particular position within

Title: Physical and Chemical Properties Purpose: The purpose of this experiment is to investigate the physical and chemical properties of pure chemical substances by subjecting them to various environmental extremes. Procedure: Filled each test tube with substances provided and subjected them to various conditions. These conditions included‚ heat‚ cold water‚ hot water‚ acid and basic additions and tested on litmus paper. The reactions were observed and documented at each step. Data tables:

Manual Testing Faq’s What is software testing? Software testing is the process used to help identify the correctness‚ completeness‚ security‚ and quality of developed computer software. Testing involves operation of a system or application under controlled conditions and evaluating the results. Controlled conditions should include both normal and abnormal Why Management some times not serious about testing? Solving problems is a high-visibility process; preventing problems is low-visibility
