first part‚ we began by measuring the initial position of the mass hanger with 200g from a spring attached to a support stand. Next‚ data for position and mass were recorded for each 100 gram weight that was added to the hanger up to a total of 700 grams. Data was recorded again with the removal of each 100 gram weight for uncertainty purposes. The data was entered in Graphical Analysis and graph for displacement vs. elastic force was created. In the second part‚ the same procedure was performed

Title: The Feasibility of Lemon Grass Extract as Anti-oxidant Abstract: This research aims to determine the ideal amount of quality effect for using anti – oxidant by getting the extract of lemon grass. The lemon grasses were chopped at the constant size and pressured afterwards and were tested for their physical appearance and effeitinity. After the preliminary test in finding out the best insulator for the making of anti – oxidant out of extract lemon grass. 46 people were tested in

by Bacillus sp.: The microorganisms in the most contaminated toilet Sink were isolated by dilution technique. The dominant bacterial strains are identified as Bacillus sp.‚ on the basis of morphological and biochemical characteristics. Gram’s staining: Gram positive and rod shape. They were serially diluted and spread on nutrient agar plates. The starch has been hydrolyzed and a clear zone by the addition of iodine solution. Visual identification: When bacterial biomass mixed with silver nitrate

9/25/13 Endothermic Reaction Lab Report The Effect Ammonium Nitrate has on the Temperature of Water During this lab students are going to mix water and ammonium nitrate one gram at a time and observe the change in temperature that is occurring. The students are then going to record the data on a table and later will be able to make a graph of the results. A hypothesis for this lab could be if ammonium nitrate is added to water then the water temperature will decrease. . Hypothesis: If

3.4 Linear Programming Linear programming is one of the most useful types of word problems we learn in Algebra 2. It takes a collection of information and produces the best possible solution. However‚ each problem is unique. This requires an overall understanding of how to set these up. You need to buy some filing cabinets. You know that Cabinet X costs $10 per unit‚ requires six square feet of floor space‚ and holds eight cubic feet of files. Cabinet Y costs $20 per unit‚ requires eight square
