Internet Advertising Essay -- Computers Technology Media Essays

Internet Advertising The November cover story for Newsweek was entitled â€Å"e-life† and the issue was dedicated to the many ways that the Internet is changing our lives and work. While the changes have affected many industries and many jobs, one of the biggest changes in marketing and sales is the rapid and unpredictable growth of Internet-based sales and advertising. Currently, many users benefit from the use of â€Å"free† email sites and Web-search portals, all of which are funded by revenues from banner advertising. (Sadly for these advertisers, many are increasingly able to ignore this stimulus). All types of businesses now want to reach an audience that is more consistently â€Å"logged on† to the Internet. If the Internet is where the customers are to be found, then that is where advertisers must go. While many of us are acutely aware of this fact, few of us know enough about how to place ads, what types of ads are available, and how the industry is changing. This paper is dedicated to understanding this topic further. The Context: Who Is Spending On Ads and How Much? In 1997, businesses spent $600 million on Internet advertising, and Internet ad spending rose to $1 billion in 1998.[1] To put these numbers in context, it is useful to compare the growth in Web advertising to the growth in non-Web advertising[2]: Year Web Advertising Spending $ Non-Web Ad Spending $ 1997 600M 133 Trillion 1998 1B 155 Trillion Such a table indicates clearly that Internet ad spending doubled while non-Web spending grew by 17%, and these numbers give marketers some sense of the urgency and immediacy of the need to learn about Web-based advertising. Interestingly, marketers have caught on: studies show that total I... ...arketers in cyberspace are: consider what type of ads you want to place, consider carefully how you plan to measure success of your campaign- attempt to monitor mindshare as well as final sales.

Hydrogen Gas Lab Essay

* For the mass, an uncertainty of0.01g was used, as the uncertainty was stated on the weighing machine. * For the volume, an uncertainty of0.05mL was used, as it was half the smallest increment on the graduated cylinder. * For the temperature, an uncertainty of0.5 was used, as it was half the smallest increment on the thermometer. Sample Calculation Converting mL to L Data Processing: Magnesium+HCl Reaction -Finding the molar volume at STP of hydrogen gas when HCl is reacted with magnesium. Finding Pressure of (Pressure of H2O at 21=0.02763) Finding Volume of at STP 0.002 Sample Calculation Finding Uncertainty for Finding moles of Moles of Finding Molar Volume of at STP. Zinc+HCl Reaction – Experimentally calculating molar mass of zinc using the ideal gas laws. Finding Pressure of (Pressure of H2O at 21=0.02763) Finding Moles of Determining Molar Mass of Zn Conclusion: In conclusion it was found that the molar volume of hydrogen gas that was produced when hydrochloric acid reacted with magnesium was 19L/mol3. Ideally it should be 22.4L/mol according to the ideal gas laws. There is a percent difference of 15% between the two values. But if uncertainties are considered the percent difference is reduced to 2%. This is an acceptable value because the actual value of 22.4L/mol is an approximation in ideal conditions according to the ideal gas laws. The ideal gas laws don’t take into consideration the attractive forces between atoms, or the volume of the atoms. And most likely if those factors were considered then the percent difference would be 0%. For the second part of the experiment it was experimentally found using the ideal gas laws that the molar mass of zinc is 124 g/mol. When compared with the actual value of 65g/mol, there is a percent difference of 90%. And even if uncertainties are considered, the percent difference is only reduced to 64%. This is too big; therefore the data is rendered unreliable. There were quite a few weaknesses and limitations in this lab. First of all the volume of H2O mixed in with the H2 gas was not considered. Had it been considered, then the volume found at STP would have been lower, and it would give a more accurate measurement to what the experimental value is. Another weakness in this lab was the fact that the molar mass of zinc was twice as big as its accepted value. The most likely reason for this is that when the zinc reacted, it is likely that some of the hydrogen gas was not in the beaker, but the hydrogen gas escaped into the air. That is why when the formula n=PV/RT was used, the volume in the numerator was half as big as it should be, which in turn caused the calculated molar mass to double. So it can be assumed that approximately half the hydrogen gas escaped into the air. Another weakness was the fact that the apparatus was left over night, and so if there was a microscopic hole or crack, then the chances of the hydrogen escaping is very high. This would be true because, and since hydrogen has the lowest molar mass of all the elements, it would have a very high velocity, and so it is possible that the hydrogen gas was able to escape through a microscopic hole at a fast rate because it has such a high velocity. Not only that, but since it was left overnight, it would have had more time to escape the beaker. There are a number of ways that this lab could be improved. First of all, a new graduated cylinder should be used to ensure that there are no cracks or holes through which the hydrogen gas can escape. Along with that the apparatus should not be left out overnight, but instead the reaction should be speeded up by heating up the apparatus, and then taking the measurements of the volume of gas every 1 minute. This in turn would decrease the amount of energy lost to the environment, and it would end up giving more accurate results. Next time, the volume of should also be considered. A percentage value can be used, since we know the pressure that gives, that pressure can be converted into a percent, and multiplies by the total volume, and then inversed. This in turn will in turn give the volume of .This will hold true because V=nRT/P, so pressure and volume are inversely proportional, and since nRT is a constant V and P have to change accordingly.

Invisible Man By Ralph Ellison - 1283 Words

Invisible Man, by Ralph Ellison, tells the story of a young, educated black man as he travels from the Deep South to the streets of Harlem, experiencing the oppression and the struggles of a dominantly white society. The narrator, who remains nameless throughout the entire novel, is on a search for his true identity. Along the way he meets many powerful white men who are more than willing to define him, often in the form of a document. While these papers seem to foreshadow good fortune for the narrator (whom I will refer to as IM), they are filled with nothing more than false dreams, and an underlying message to â€Å"keep this nigger- boy running.† The motif of documents is prevalent throughout Invisible Man, as IM accumulates several important papers such as his scholarship, his new Brotherhood identity, and the warning letter from Brother Jack. Each defines a social role, but together they show how the white men strive to keep IM â€Å"running a footrace against [himself]à ¢â‚¬ (380). One of the first documents IM receives is his scholarship from the white men after the â€Å"battle royal†. This is one of the most pivotal documents in the novel, as without it, IM’s search for his identity would never begin. IM is overjoyed to receive a scholarship to the state college for Negroes from the big shot white men of his town. Even more, he is pleased that his yess’m-ing has finally paid off. This scholarship defines and sets IM apart from the rest of the black boys in his town, and gives him theShow MoreRelatedInvisible Man By Ralph Ellison1366 Words   |  6 Pagesfighter left standing, amidst unbridled carnage.
