Metals and corronslon - Lab Report Example Metals react with acids to give the metal salt and water. The purpose of this experiment is the determination of the different properties of metals. The properties determined include conductivity, hardiness, and Brittleness. Also, the ability of copper, iron and brass to resist corrosion was investigated in this experiment. All the three metals were placed in three different open beakers containing tap water and left there for 3 days. After the tree days, it the changes in the physical appearance of the metal was observed and recorded When one end of the three metals were heated and time taken for the heat to be transfred from the end being heated to the other opposite end taken, it was found that it was faster in copper than in iron and brass. From the experiment, it can be determined that iron and brass are prone to corrosion as compared to copper. Also, comparison of the brittleness of the three indicates that iron is more brittle as compared to copper and brass. The alloy of copper and iron, brass is harder than the pure metals. From the experiment, it can be concluded that copper metal is a good conductor of heat, iron is more brittle and brass is harder. Also, it can be conclude that, substances containing iron are more prone to corrosion as compared to substance lacking iron. This due to the presence of iron II Oxide that is converted to iron III Oxide which is the rust that causes

President Obama and Agenda for Possible Second Term Essay

President Obama and Agenda for Possible Second Term - Essay Example Over the years, through the development of broadcast technology, candidates are given an opportunity by the media to sell their policies through a public debate. This platform helps them to improve on their campaigns, and it assists the voters to evaluate also the candidates. The communication advisor is necessary during the campaign period because he advises the candidate and party on what strategies to use to ensure victory in the elections. As a communication advisor in the Barrack Obama campaign team in the current elections, I would suggest prioritization of some issues during the final weeks of the campaign. This essay will highlight the current trending issues in the country’s politics, and advice on some arguments and the positions that the team should emphasize on. During the final campaign weeks, some issues should not be emphasized on as shall be pointed out in the essay; moreover, the last weeks of campaigning are prominent in gathering the votes of the undecided v oters, and developing trust from the voters on the direction, which the country should take. Political structures are social structures in the society; therefore, the campaign teams need to consider the social dynamics in the society for their success. The key factor is that campaigns involve communication of messages to the public with an objective of getting their support during the elections. Therefore, it is necessary to design the message to appeal to the voters (White, 2010). In addition, the social judgment theory applies to every person because people hear a message then they compare it with another, and they make a judgment on where to place it in the different mental categories. Further, people develop some mental yardsticks (Latitudes) of acceptance, rejection and non-commitment to a message. Therefore, in the case of Obama’s campaign, one needs to know what and how to communicate messages to the public in order to persuade them towards the desired direction or vot ing. In Obama’s campaign, the use of persuasive social skills to influence voters is easier than in Romney’s team because Obama has excellent, persuasive skills through his speech. Persuasion and influence of people is necessary in all the social theories, and is essential to getting people to accept the party’s political ideologies and policies. In the current political campaign, the candidates are contesting in their campaigns on several issues. Some of them include foreign policies, energy, education, healthcare and the economy. In this presidential campaign, I would suggest that the issues to do with foreign policy and energy should not be focused on by the Obama Campaign team during the last weeks towards elections. This is because the policies and suggestions on these issues are not different to the ones used in the previous four years of the Obama Administration. Therefore, based on the consistency theory, people do not expect them to change so the campai gn should focus on other, different issues (Clarke, 2008). In the economic, education and healthcare issues, there are many differences in policies between the candidates and hence, the campaign should emphasize on them in order to develop proper social judgment from the voters.

The Law of Comparative Advantage Essay Example | Topics and Well Written Essays - 2000 words

The Law of Comparative Advantage - Essay Example Because the theory failed to understand the laws of absolute and comparative advantage, which advocates that trade, may not necessarily be a zero-sum game, mercantilists regulations were gradually removed in Britain in the course of eighteenth century after the government has fully embraced Adam Smith's concept of laissez faire (Wikimedia Foundations, Inc). The greatest challenge to mercantilism was Adam Smith's theory of absolute advantage. It is said that Smith's publication of the book The Wealth of Nation in 1776 has ended the rule of mercantilism as an economic philosophy. In contrast to the necessity of government control in the mercantilists' philosophy, Adam Smith advocated the laissez faire system, with limited government intervention in the economy. Particularly, Smith believe that trade would be beneficial to both countries through specialization. In practical terms, when one country is more efficient than another country in the production of one commodity but is less efficient in the production of another, then both can gain by specializing in the commodity in which it has the absolute advantage. ... As trade is deemed beneficial to all, restrictions are discouraged and limited government intervention is advised. An Unchallenged Theory An enhancement and definitely a higher notch than the theory of absolute advantage is the law that says that one country can benefit from trade even if it is less efficient in the production of both commodities. It is the law of comparative advantage: an impetus for small nations to actively participate in trade as it is believed to benefit both the big and the small countries. Introduced by David Ricardo in 1817 through his book On the Principles of Political Economy and Taxation, comparative advantage posits that trade can create value for both countries even if one has the fewer resources in the production of all goods. Using the production possibilities frontier, Ricardo was able to prove this, achieving a significant breakthrough in the field of international economics. Practically, Ricardo believes that given the situation, both countries can still gain by having the less efficient country specialize in the production and exportation of the commodity in which its absolute disadvantage is smallest and import the product in which it has its greatest absolute disadvantage. The commodity in which one country has the least absolute disadvantage can be thought of as one in which it has the comparative advantage. The gains are realized as both countries specialize in the production of commodity in which it has the least opportunity cost (Mankiw). The Gains from Trade: A Simple Numerical Example To facilitate understanding of the gains from trade, we cite the example from the Principles of Macroeconomics book of N. Gregory Mankiw. Given that it takes 20 hours for farmer to produce 1 lb of meat and 10 hours to produce 1
