Density of Metals Problem: How does the mass and volume help determine the density of known metal samples? Hypothesis: When comparing the density of Zn(zinc) and Cu(copper)‚ you will find that Copper is more dense than Zinc. You can test this out by using the density formula D=m/v. Materials: * 2 metals (options: zn‚ al‚ or cu) * 3 samples of each metal (small‚ medium‚ and large) * Scale/Balance * Calculator * Water * Graduated Cylinder Safety: * Be prepared for your

Consumer behavior or elasticity is a consumer’s response to a change in price of a good or service. Consumer behavior allows a consumer to rank and prioritize purchases according to their elasticity of certain goods and their dependence on others (Managerial Economics‚ 2010). When consumers recognize a change in price and respond strongly‚ they can adjust their consumption and therefore have their demand for that item become elastic. Automobiles tend to have elasticity in them in regards to make

Google Case What were the key factors behind Google’s early success? The main key factor for Google’s early success was the creation of PageRank algorithm. Stanford graduate students Sergey Brin and Larry Page transformed the spam problem of all search engines into an opportunity by creating an algorithm that favored pages that were referenced by other pages rather than simply counting key words. The page’s importance was determined by counting its inbound links‚ weighting the links more heavily
