History of Electricity Our knowledge of electricity has started from very humble beginnings when you look at where we are today. Electricity has been around for as long as humans have. When lightning strikes ancient people may not have understood what it was or why it happened‚ but they at the very least witnessed it happen. Nature acted as a sort of catalyst to spark the curiosity of early people. It was only until sometime between 624 BC and 546 BC where an understanding of electricity began to

Chapter 3 #2 - When is a company’s competitive advantage most likely to endure over time? A company’s competitive advantage is most likely to endure over time when the company has built barriers to imitation‚ which make it difficult for a competitor to copy the company’s distinctive competencies. Another element needed is the ability to quickly react to changes in the customer’s needs and have a high absorptive capacity in order to identify‚ value‚ assimilate‚ and use new knowledge. Lastly‚ the

PHYSICAL PROPERTIES OF THE PERIOD 3 OXIDES These pages explain the relationship between the physical properties of the oxides of Period 3 elements (sodium to chlorine) and their structures. Argon is obviously omitted because it doesn’t form an oxide. A quick summary of the trends The oxides The oxides we’ll be looking at are: |Na2O |MgO |Al2O3 |SiO2 |P4O10 |SO3 |Cl2O7 | | | | | |P4O6 |SO2 |Cl2O

Place is when your products will be offered‚ there location. A company wants there product in the right stores so people can see it and buy it. An example of this is selling cereal. You would rather have a big supermarket have you product then a little deli. A supermarket will sell more of your product. The problem with the four P’s is that this is all about the producer’s point of view. They don’t go buy the consumers. A lot of company’s want the consumers point of view so they use the 4 C’s. The

amount of dissolved NaCl in water effect the volume of one drop? Aim: This experiment plans to measure the volume of one drop of water and compare it the volume of one drop of sodium chloride solution. What will be attempted by this experiment is to measure the volume of one drop of distilled water by measuring a control and comparing it the volume of one drop of distilled water with dissolved NaCl. This will be done by using a burette for dropping the distilled water and a electrolyte solution. Hypothesis:
