Static Electricity

Everything is made up of tiny particles called atoms. The atoms are made up of even smaller parts called protons, electrons and neutrons. Protons have a positive charge (+), electrons have a negative charge (-) and neutrons have no charge at all, they are neutral. Atoms normally have the same amount of electrons and protons, making them neutral and having no charge. When rubbing things together, electrons can move from one atom to another, resulting in some atoms having extra electrons and a negative charge.The other atoms now have more protons than electrons and a positive charge. When the charges are separated, it is static electricity. â€Å"Electricity is present in all matter in the form of electrons and protons. Any device that develops and maintains a voltage can be considered a voltage source. To accomplish this, the voltage source must remove electrons from one point and transfer electrons to a second point. † (Petruzella, 2001. ) One type of electricity is static ele ctricity. The term static means standing still which makes static electricity an electric charge that is at rest.Static electricity is defined as â€Å"an accumulation of electric charge on an insulated body. † (Free Dictionary) In other words, it is a charge that is created when two objects that are not good electrical conductors are rubbed together, and electrons from one of the object rub off onto the other object. Some of the results of static electricity may be sparks, shocks, or even materials clinging together. The simplest way to form static electricity is by friction. Friction is simply the rubbing of one object against another.By rubbing two different materials together, â€Å"electrons may be forced out of their valence shells in one material and picked up in the shell of the other material. The material that gives up electrons more freely becomes positively charged and the one that gains electrons becomes negatively charged. † (Petruzella, 2001. ) When the electrons are relocated from one material to another, it is called triboelectric charging. Static electricity is formed much better in areas with low humidity and dry air. With humid air, tiny water molecules can collect on the surface of different materials and prevent the buildup of an electrical charge.Although small amounts of water, such as those developed from humidity, can affect a charge, â€Å"extreme turbulence among water drops†, such as in a thunderstorm cloud, can cause static electricity to build up on the water droplets themselves. Benjamin Franklin showed that static electricity is created in a thunderstorm cloud by flying a kite during a storm. He noticed the static electricity by seeing the hairs on the kite stand on end and created an electric spark with a metal key. There are other ways to produce a static charge other than friction or contact.An object can also be charged by induction. Induction is used to produce a charge of opposite polarity. Inductance is defined in the text as an â€Å"electrical property which opposes change in current. † (Petruzella, 2001. ) An inductor is â€Å"a device that generates a counter emf that tends to oppose any change in current through the use of ac current flowing through a coil wire. † (Petruzella, 2001. ) Charging by induction makes use of the electrostatic field surrounding a charged body in order to charge an object without touching it.If a negatively charged rod is brought close to the sphere on the inductor, the negative charges in the sphere move as far away from the rod as possible. By touching the sphere, it is grounded and allows the electrons to completely leave the sphere. Once you remove your finger, the electrons no longer have a way of returning to the sphere and the rod is then positively charged. Static electrical charge can be produced by a high-voltage direct current source. Many air purifiers use both positively and negatively charged plates to remove tiny dirt particles from the air.This system uses an electrostatic precipitator and oppositely charged grids. The dirty air moves through the precipitator which gives the dirt particles a positive charge. All of those particles are then attracted to the negatively charged grid and then the air passes through a carbon filter to remove any odors. Static electricity is also used with photography to work a photocopier. An â€Å"electrostatically charged drum† attracts toner particles to the image in the original document. The metal drum inside the machine is charged at the eginning of each copy. The system inside the photocopier then puts an image of the document onto the drum. The electric charge goes away wherever light shines on the drum and so only the dark parts of the image are still charged on the metal surface. The particles of black toner are oppositely charged and then applied to the drum. The charged parts, which contain the image, are attracted to the toner and transferred to t he paper and finally attached to the paper with heat. Static electricity can cause materials to attract or repel each other.If you use a hair dryer on your hair and then comb through it or just comb it on a very dry day, the plastic comb will collect negative charges from the hair and leave the hair with an excess amount of positive charges. Since like charges repel, the hair strands will push away from each other causing your hair to stand up or â€Å"flyaway. † Static electricity can also cause a spark to jump from one material to another, like when you touch someone and â€Å"shock† them. As you walk across something like a carpet, electrons cling to you.When you have extra electrons, you then have a negative charge and are attracted to positive charges so once you touch someone else, assuming they have a positive charge, you will feel a tiny shock which is a quick movement of electrons. If there are enough positive electrical charges on one object or material and e nough negative charges on another, the attraction may be so great that the electrons will jump to the other object with out the two touching. After a few electrons make the jump, the air begins to heat up and causes more and more electrons to move and the air to get even hotter.This all happens so fast and causes the air to get so hot that it glows for a split second and is known as a spark. The same process occurs with lightning only on a much larger scale. Removing or preventing a static charge can be very simple such as opening a window or using an air humidifier to â€Å"increase the moisture content of the air and make the atmosphere more conductive. † (Wikipedia) Items that are very sensitive to static discharge can be treated with an antistatic agent. Wikipedia defines an antistatic agent as something that â€Å"adds a conducting urface layer which ensures that any excess charge is evenly distributed. † An example of an antistatic agent is fabric softener or dry er sheets which are used in your laundry to prevent and remove static cling. â€Å"Semiconductor devices† which are used in electronics are very sensitive to static charge. These devices are protected using antistatic bags and those who work with these devices ground themselves by wearing conductive antistatic straps to protect their bodies. To test for a charge on an object, you must see how that object affects another object with a known charge.If the two objects repel, that means their charges are alike and if they attract, the charges are opposite. To see if an object is neutral, test it with another neutral object. Neutral objects do not attract with each other, only with another positive or negative object. â€Å"An aluminum-leaf electroscope is a device for detecting the presence of an electric charge and also for determining whether the charge is positive or negative. † (Petruzella, 2001. ) This device is made up of a flask with an insulating stopper. A metal r od goes through the center of the stopper and a metal knob is fastened to the outside end of the rod.Two very thin pieces of aluminum are attached to the other end of the rod inside the flask. â€Å"Normally the positive and negative charges within the electroscope balance each other, leaving it neutral. When a negatively charged body touches the knob of the electroscope, electrons flow from the charged body into the knob and down to the aluminum leaves. Each leaf then becomes negatively charged. Since like charges repel and both leaves are negative, they will diverge, indicating that the object contained a static charge. † (Petruzella, 2001. )In conclusion, static electricity is all around us. It may clean our air or be the cause of a terrible hair day but has both positive and negative effects on many daily routines.Work Cited Page Petruzella, Frank. Essentials of Electronics. Second Ed.

Leadership - MBA - Essay Example Thus the only thing that will be found common between various leadership styles will be the â€Å"social influence† (Robert K. & Angelo K., 2004). This factor is the key in leadership. There are a number of leadership styles that are proposed in various books journals, periodicals and the internet. In this paper, only some of them are discussed very briefly as it is not possible to discuss each and every leadership style also these are discussed briefly so that these can be applied to the selected organization in much more detail. But are these styles of leadership actually followed in the organizations today? To look into the practical application of the various leadership styles, a company that specializes in the manufacturing of computer hardware components, Softech Company is selected and leadership styles followed at two different levels of management are discussed and analyzed. There is an in-depth analysis conducted on the style of leadership that these managers follow and the way they deal with their subordinates and what influence their subordinates have through their personalities. For the purpose of analyzing the application of leadership, Softech Company was selected. The company background and rationale for selection is discussed later in the paper. Two levels of the organization were focused for the analysis of the leadership style possessed by the leaders. One top level executive was chosen for the purpose of analysis and another middle level manager’s leadership style was studied. The names and complete designations are kept confidential as the respondents didn’t want to disclose this information. The styles of these managers vary broadly in terms of their approach to the tasks and subordinates. Unlike the trait theory, the behavioral aspect of leadership focuses on the behaviors of the leaders which largely influence their followers (Sadler, P., 1997). In this respect a number of

Marketing - Essay Example In the current case, an expensive line of women bathing suit is to be launched internationally. For this, the bathing line will have to create strategic alliance either with the host nation or with a local organization. The various criteria for choosing a country are as follows: Political assessment- It means accessing government stability as well as friendliness to foreign market entrants. Economic assessment- It involves documenting and analyzing of economic indicators such as, health, foreign investment activities, taxes as well as history or mergers and acquisitions. Social assessment- It involves collection of demographic information such as, age, employment rates, income history and population. Infrastructure assessment- It involves evaluation of ground conditions like, power, roads as well as telecommunications reliability. Legal assessment- It includes preparation of all regulatory compliances which the company is not following currently. Each of the countries chosen, Brazil, UAE and Spain are politically and economically suitable for the expansion business. Also, the infrastructure in all three countries is well established and shows constant growth (Lawrence, 2000). Brazil and UAE are major emerging economies and Spain has an established market for luxury swimsuit line for women. Thus, all these three countries are suitable according to most of the chosen criteria. Marketing communication Before entering into an international market, it is extremely important to understand the foreign market and the industry environment. Before marketing communication planning, the Swimsuit Company will have to look into following criteria: Assessment of growth potential It involves projecting realistic and opportunistic growth trajectory after entry into the market. Spain is one of the major European markets for swimsuits, after Italy and France. The overall yearly swimsuit sales are increasing. This can be attributed to huge tourist footfalls as well as local market consumption. Brazil has become one of the hottest destinations for luxury apparel market, as a result of increasing number of international brands as well as affordability among consumers. Even though apparel sector has seen a constant growth in UAE, the sale of men’s luxury swimsuits is much more than the ones for women. Competitor evaluation It involves identification of top players in the industry. Spain is the home for some of the top-notch luxury swimsuit brands such as, Women’s secret and Oysho, which are market leaders. Other prominent market leaders are Andres Sarda, TCN and Selmark. Brazil is still an emerging market in terms of luxury swimwear. Local brands such as, Gap and H&M, are not doing a good job. Brazil has the opportunity for luxury swimsuit market. Most of the women swimsuits in UAE are available only in malls. Customer evaluation It involves gathering customer behavior insights which can help in making useful adjustments in product designs as well as marketing communication strategies (Young & Aitken, 2007). Tools such as, fit matrix and customer opportunity matrix, can be used. As discussed earlier, both Brazil and Spain are preferable markets for expansion. However, Spain can be considered as a mature market and competition will be tough. Compared to this, Brazil has fewer competitors in luxury swimsuits category and market demand is constantly increasing. Pricing and positioning analysis It is important to forecast appropriate approaches

The PR Function Video Essay Example | Topics and Well Written Essays - 250 words

The PR Function Video - Essay Example PR exists in effective communications and is most importantly under control of the media (Smith & Place, 2013). Business enterprises use the media to promote brands and images. Such undertakings continuously engage the public to identify with the respective companies. There exist numerous PR strategies. Notably, reputation of an organization is always at a stake whenever it or its stakeholders engage in activities that activities that might compromise public image. Therefore, every company must engage relevant agencies in building self-image and restoring public trust. Publicizing a business is only effective if the consumer response is positive and the target audience take no offense for the nature of brand display (Smith & Navarro, 2014). PR differs from advertising concerning the control of marketing media. For instance, a company has full control over what is put forward for the audience in advertising. Whether in television of newspaper columns, business dictates the kind of images to use for brand or service promotion. On the contrary, there are regulatory mechanisms for PR that restricts businesses. Such limitations mostly focus on protecting the audience (Bernays, 2013).The image of a company is highly significant than promoting products. Believability is the most important aspect of PR.

From Data to Decision - Essay Example The data sets have been graphed accordingly as histograms in the graphs presented below. The graphs presented above clearly show that the best actors in the range between 0 and 30 are only 3 which represent only 3.8% of the entire data set. In contrasts the best actresses in this classification are 30 that represent 37.8% of the entire data set making it exceptionally high. Furthermore, as the classifications in the best actors categories proceeds the frequency increases most in the range between 31 and 60 with the greatest expansion in the range between 41 and 50 claiming a frequency of 31. In contrast, the best actresses graph tends to display the greatest frequencies between 0 and 41 with a total of 60. This is out of a total of 79 which in turn makes that best actresses graph skewed towards these age ranges. In contrast the best actor graph is somewhat centrally distributed around the 41 to 50

Civil Liberties, Habeas Corpus Essay Example for Free

Civil Liberties, Habeas Corpus Essay Civil Liberties, Habeas Corpus, and the War on Terror have all played a role throughout history. Throughout history, the motivation of man’s self interest has concluded in the domination of those with little or no power in the absence of the rule of law. The war on terror presents an unpredictable challenge for the United States since terrorists are apprehended and deprived of due process. Habeas corpus is considered to be one of the most fundamental guarantees of personal liberty that we cherished as a country since the inception of our Constitution. However, debates have arisen regarding the proper use of habeas corpus making the focus be brought back in the past decade. Since September 11, 2001 terrorist attack on the United States, many people have been detained by the U. S. government as part of its war on terror. Many of these detainees face indefinite detention and have not yet been charged with a crime. The right of Habeas corpus overrules man’s interpretation and allows those accused federal and state court representation before a judge, or jury. The accusers deemed innocent until proven guilty, they have the right to representation, and appear in person for the charges brought forth. The purpose of this paper is to show how Habeas corpus came about, and its suspension by the United States. Also, the war on terror will be addressed along with the Supreme Court’s interpretation. Learning the history of Habeas corpus and how it works, allows us to see just how these laws are supposed to be carried out from our Constitution and not to be reconciled with. Habeas corpus is a judicially enforceable order issued by a court of law to the prison official ordering that a prisoner be brought to court so it can be determined whether or not has been lawfully imprisoned or should be released from custody. The right of Habeas corpus is the constitutionally bestowed right of a person to present evidence before a court of law, showing that he/she has been wrongly imprisoned. Habeas corpus is granted in Article l of the Constitution which states, â€Å"The Privilege of the Writ of Habeas Corpus shall not be suspended, unless when in Cases of Rebellion or Invasion the Public Safety may require it. (Farrell, Iowa College) Habeas Corpus Petition is a petition filed with a court when someone objects to his own or another’s imprisonment. The petition mush show that the court ordering the imprisonment made a legal or factual error. The laws are put forth for a fair trial and freedom from laws passed after the fact. Ultimately, they protect us from the whim of those powers, and distinguish a government of laws from government of men. The historical evolution of Habeas corpus born from the Magna Carta, known as the English Bill of Rights, began in England in the early 1200s. King John of England initiated long drawn out wars against people. Growing tired of King John’s lack of leadership, concerned for the citizens they decided to come up with the Magna Carta which would limit the amount of power his Monarchy had. By means of fear and violence the Baron’s forced the King to accept and acknowledge the agreement that would honor the constitutional rights, privilege, and the greater protection of the people. Upon signing it meant that it would be null and void forever. (Harringer, K.  J, 2011) The Magna Carta states, â€Å"no free man shall be taken or imprisoned or diseased or exiled or in any other way destroyed except by the lawful judgment of their peers or by the law of the land†. (Obban, 2011) Habeas corpus was unknown to many civil law systems in Europe. European civil law systems generally favored authority from the top down whereas Angelo-Saxon common law tends to favor the individual. The Angelo-Saxon common law comes from England, after the English Civil War and the beheading of King Charles l in 1649; it led to establishing a clear position between King and citizen. Therefore, all the confrontation of top to bottom civil law principles continuously kept yielding with the ancient but law of the land. As a feature of common law, the right of Habeas corpus reflects the age old contest between individual and the state. Habeas corpus empowers the individual in holding accountable the exercise of the states power to influence liberty. Our founding fathers were well aware of the Magna Carta, and its astonishing abilities to be something great especially James Madison who was the primary architect of the American Bill of Rights. Greatly influenced by the potential of the agreement, James Madison began his own interpretation. James Madison borrowed heavily from Article 39 of the Magna Carta which limited the legislative power. Madison was a key player in growing that particular article into the Bill of Rights. It was through Magna Carta and our founding fathers interpretation of that article that the American courts used and still use today when interpreting the rights of enemy combatants. (Halliday, 2011) September 24th 1862 Lincoln issued a proclamation suspending the writs of Habeas corpus nationwide and specified whose rights would be suspended. All traitors and rebel militias against the U. S. shall be subject to martial law and liable to trial and punishment. (Longley, 2012) In 1866 after the American Civil War had ended the Supreme Court officially and fully restored Habeas corpus throughout the entire nation. That would not be the first time a president would suspend the writ of Habeas corpus. On October 17, 2006 President George Bush suspended the right of Habeas corpus by determining that certain persons were in fact â€Å"enemy combatant† during the Global War on Terror. It came about from before the September 11, 2001 terrorists attacks, hundreds of people have been detained by the United States government as part of its war on terror at locations such as the Guantanamo Bay Naval Base in Cuba and Bagram Airfield in Afghanistan. Most of these detainees have faced indefinite detention and have neither been charged with a crime nor afforded prisoner of war Status. Many of these prisoners have sought out to use Habeas corpus proceedings to challenge the legality of their detention. However, the government decided that their status as â€Å"enemy combatants† outside of the sovereign territory of the United States. In 2004, the United States Supreme Court determined that non-citizen detainees at Guantanamo Bay were entitled to file habeas corpus petitions in federal courts. Congress subsequently made a political determination as to the appropriate scope of habeas corpus and passed legislation that stripped federal courts of jurisdiction to hear Habeas corpus petitions brought by enemy combatants. However, the ruling was shortly overturned which led to President George Bush signing the law of suspending the right of habeas corpus. President Bush’s action drew severe criticism, mainly for the law’s failure to specifically designate who in the United States will determine who is and who is not an â€Å"enemy combatant†. Both presidents received sharp criticism for carrying out what many believed to be an attack on the Constitution. President Bush suspended writs of Habeas corpus through his support and signing into law of the Military Commissions Act of 2006. The bill grants the President of the United States almost unlimited authority in establishing and conducting military commissions to try persons held by the U. S. on the Global War of Terrorism. In addition, the Act suspends the right of â€Å"unlawful enemy combatants† to present, or to have presented in their behalf. On June 12, 2008, the Supreme Court ruled in Boumediene v. Bush, 5 to 4 that Guantanamo captives were entitled to access the U. S. justice system. Justice Anthony Kennedy wrote in the majority opinion: The laws and Constitution are designed to survive, and remain in force, in extraordinary times. The Court also ruled that the Combatant Status Review Tribunals were â€Å"inadequate†. Chief Justice John Stevens joined Kennedy in the majority. Chief Justice John Roberts, in the minority opinion, called the CSR Tribunals the most generous set of procedural protections ever afforded aliens detained by this country as â€Å"enemy combatants†. The Supreme Court ruling responded by Vincent Warren (executive director of the Center for Constitutional Rights) actions. The Supreme Court has finally given the men held at Guantanamo the justice that always deserved. By granting the right of Habeas corpus, the Supreme Court recognizes a rule of law that was established hundreds of years ago. This 6 year long crisis is a lesson on how fragile our constitutional protections truly are in the hands of very persistent executives. The role of presidents is a very hot topic throughout history on how they will act when the occasion arises with war on terror. I believe that many presidents have abused their power in the past against the Constitution and have taken measures into their own hands. The role of the president is one of the hardest occupations out there since they decide on our fates of the future and our lives. Habeas corpus and the president’s role as commander-in-chief has to be terrifying when faced with the decision on what to do on situations of dealing with â€Å"enemy combatants†. Therefore, every president wants to carry out the Constitution, but when faced with protecting our Nation it would seem unbearable. I agree that Congress should be able to deny or overturn the president when it comes to Habeas corpus so that not just one person is deciding the fate of others. Also, the Supreme Court should be the decision in the middle for a tie breaker so everyone gets the hearing that is deserved as fair and not unconstitutional. I do have concerns when it comes to our country war on terror because this is my nation and I want to protect it also. However, everyone has the right to a fair trial and is innocent until proven guilty; we also need to stick to the laws that our founding fathers intended for us so that the government cannot bend the rules on situations. The evolution of Habeas corpus has brought out many key factors that our government needs follow. There have been many heated debates over the years on how we must not bend the laws that is why we have the Supreme Court and Congress stepping in over the commander-in-chief. Nevertheless, these laws are in place to protect everyone, moreover to avoid unlawful apprehension, and ensure that Habeas corpus works are intended by the Constitution.
