where I divided its mass by its density to get its final volume so that I can create the perfect submarine for the experiment; final density of the submarine‚ where I added up all of the mass of balloon‚ pellets‚ and rubber band and divided by the volume of sphere so that I get the final density of my submarine and test if my submarine flow appropriately.

This part of the experiment yielded an exothermic reaction. The purpose was to calculate the specific heat capacity and molar mass of the zinc metal. The specific heat capacity was found to be 0.197 J/g °C with a percent error of -49.5%. The molar mass was found to be 127 g/mol with a percent error of 94.2%. Possible sources of error inherent to this segment of the experiment were the fact that when the temperature of the solution was being measured

is still open to controversy. Does a dose of caffeine heighten one ’s mental performance‚ or does it achieve the opposite? Many experiments have already taken place in order to discover how caffeine effects a person ’s mental performance. In the Radiological Society of America ’s annual conference in December of 2005‚ Florian Koppelstatter reported an experiment in which he used functional magnetic resonance imaging(fMRI) to determine how coffee effects brain activity. Subjects were then given

Cash flow management: The life force of your businesses By LaZandrea Porter Cash flow management is a vital force to the success of any business‚ large or small. Some have compared cash flow management to the life source of the human body‚ the blood. Much like blood‚ cash keeps a business going‚ and cash flow is the circulatory system of a business. With this in mind‚ it is important to understand that managing cash flow goes beyond the generating of sales revenue. This article will aid

paradox of flow in the realm of education and schooling. Although there is much potential for flow experiences in schools‚ there tends to be a relatively small amount of flow experiences in educational settings‚ especially in academic classes. The author of this article attempts to find the reason for the lack of flow in the classroom‚ thereby enabling educators to address this problem and increase the number of flow experiences in their classes. Numerous conditions and precursors to flow are available

A. Stanford Prison Experiment- In this experiment‚ students volunteered to be a part of a psychology experiment that was being conducted at Stanford College. Because of the situation around them‚ they conformed to the environment‚ even though it was only a simple experiment in a Stanford hallway. Embarrassed and yet impressed‚ the experimenters stated this‚ “The negative‚ anti-social reactions observed were not the product of an environment created by combining a collection of deviant personalities

DFD Yourdon Recently reviewed In the late 1970s data-flow diagrams (DFDs) were introduced and popularized for structured analysis and design (Gane and Sarson 1979). DFDs show the flow of data from external entities into the system‚ showed how the data moved from one process to another‚ as well as its logical storage. Figure 1 presents an example of a DFD using the Gane and Sarson notation. There are only four symbols: Squares representing external entities‚ which are sources or destinations
