Lightning And Static Essay Example For Students

Lightning And Static Essay Lightning is a discharge of static electricity in the atmosphere, which causes a bright flash of light. When lighting goes through the air, it heats the air to degrees hotter than the suns surface about 50,000 degrees fahrenheit. This heating causes the air to expand and contract. This causes the sound called thunder. Lightning is caused by a build up of negative ions in the atmosphere which discharges into the ground causing the negative ions to go with the positive ions in the ground. Static electricity is negatively and positively charged atoms. A static charge on the other hand is a individual atom with a negative or positive charge. There are three types of charges negative positive and neutral. Negative and positive ions attract. But two negatives repel each other, just like two positives will. Neutrally charged ions can attract to both negative and positive ions, because they have and balanced charge of negative and positive ions, this means it has the same amount of negative and positive ions. This is where the following rule is true opposites attract, and likes repel. Static electricity is generated when two different objects are rubbed together and some electrons are stolen from one object and then start to collect on the surface of the other object. The object that loses electrons becomes positively charged, because electrons are negatively charged and there is an absence of electrons and too many protons. Now because opposites attract and like repel the reason hair stands up when you rub something on it can be explained. When something is rubbed in a dry place, the thing takes electrons from your hair, leaving your hair with a positive charge it stands up as far away as possible from the other positively charged hairs. There reason there is little static electricity in areas with a high humidity, like the Virgin Islands, is because the humidity in the air is a conductor of electricity, so it helps trancfer the free electrons to an area that can accept electrons, like the earth so not many free electrons stay on any object that is saturated. Static electricity can be use to do many things, one of these things is keeping down air pollution by putting an electrode in factory smoke stacks so that the dust will collect on the electrode. Lightning and static can be hazardous. lightning is harmful, some people think it does not have any threat from a distance, like when a lighting storm is up to ten miles away. The most lightning strikes take place under the lightning storm where the rain is raining the hardest. Signs to tell if lightning is going to strike in your area are, If your hair stands up you hear static popping or crackling, and if you feel you body tingle due to ions moving through your body the static on portable electronic things increases suddenly, you smell the smell of statically charged air, or you see static sparks sparking in the air around you. Things to do inside to keep from getting hurt while in a lightning storm are, get away from doorways outside, porches, windows, and good conductors of electricity. A void phones that are not cordless and if it is a cordless phone avoid it if it is on the cradle. Do not touch things that use electricity unless they are unplugged. Do not stand near or lay on concrete walls. Do not use a metal building for shelter. And dont go into the basement because the electricity can travel through the ground. To not get hurt outside, go inside if you hear thunder, if the sky looks threatening, and stay inside for at least 30 minutes after the last sound of thunder. If you are caught outside and do not have shelter close to you during a lightning storm, you should crouch to the ground, get onto the balls of your feet, put your hands on your knees, put your head between your knees, make yourself as small as you can, and try to have as little physical contact to the ground as you can. Static electricity has been known about for some time. Some time around the year 600BC the Greek Mathematician named Thales was might have been the first to record that amber rubbe d with fur would attract small light objects. In 1733 C.F. de Cistenay Dufay named the two charges of static, resinous electricity due to too many electrons, and electron deficiency electricity. Now static electricity is discovered to be a source of many problems in industry. . Static can cause problems in Industry, like in the production of plastic materials, and the transportation or use of flammable liquids. With the production of plastic materials the plastic can cause the production machines to clog, and thin strips of plastic to stick together and clog machines. With transporting or using flammable liquids a static spark can igniht a whole container of the liquid. .u9198fda96228ba4e960d88a2f8ab3b8e , .u9198fda96228ba4e960d88a2f8ab3b8e .postImageUrl , .u9198fda96228ba4e960d88a2f8ab3b8e .centered-text-area { min-height: 80px; position: relative; } .u9198fda96228ba4e960d88a2f8ab3b8e , .u9198fda96228ba4e960d88a2f8ab3b8e:hover , .u9198fda96228ba4e960d88a2f8ab3b8e:visited , .u9198fda96228ba4e960d88a2f8ab3b8e:active { border:0!important; } .u9198fda96228ba4e960d88a2f8ab3b8e .clearfix:after { content: ""; display: table; clear: both; } .u9198fda96228ba4e960d88a2f8ab3b8e { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u9198fda96228ba4e960d88a2f8ab3b8e:active , .u9198fda96228ba4e960d88a2f8ab3b8e:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u9198fda96228ba4e960d88a2f8ab3b8e .centered-text-area { width: 100%; position: relative ; } .u9198fda96228ba4e960d88a2f8ab3b8e .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u9198fda96228ba4e960d88a2f8ab3b8e .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u9198fda96228ba4e960d88a2f8ab3b8e .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u9198fda96228ba4e960d88a2f8ab3b8e:hover .ctaButton { background-color: #34495E!important; } .u9198fda96228ba4e960d88a2f8ab3b8e .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u9198fda96228ba4e960d88a2f8ab3b8e .u9198fda96228ba4e960d88a2f8ab3b8e-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u9198fda96228ba4e960d88a2f8ab3b8e:after { content: ""; display: block; clear: both; } READ: BUS 640 Week Two Assignment Paper EssaySome techniques were developed to help prevent static problems with the production of static , the two major techniques are chemicals, or the use of carbon and or metal fillers. With the chemical way of controlling static the chemicals are mixed with the molding palettes or powder. The second way is to apply the chemicals directly to the surface of the plastic that has the molding. These two chemical methods work, because they help distribute the static into the air, by increasing the conductivity of the plastic. With the metal/carbon filler method you mix in the metal or carbon pellets in with the molding pellets/dust. This way works because it helps bring up the conductivity of the plastic molded with the fillers. Although these techniques for getting of the static may sound good, there are drawbacks, like with all good things. The chemical method corrodes the machinery and lets bacteria and/or fungus to grow in the product or production equipment it also easily wear out. The metal/carbon filler has its own set of problems, They either work themselves out of the product, because the fillers dont mix well with the plastic, and cause the work areas to get dirty (can be a major problem in some areas). The fillers also make plastic opaque, so that will make it difficult to track while being produced. This is bad because the product would need to be tracked to see how efficient the work is going. There are three major techniques for preventing static electricity in the transportation storage transference and use of flammable liquids. The first way is by bonding two containers when transferring the liquid between th em. What you do in bonding is you take something that can conduct electricity and you connect it between the two containers. What bonding is to do is make the static charges in the containers about equal, so that there will not be much static potential energy, and no sparks will form while transferring liquid, most of the transferring pumps that are made have special grounding things in their transfer hoses. Another way to prevent static electricity build up in the storage of conductive containers of the liquid is to ground them. You can ground things by connecting the containers on metal, or conductive material that is some how driven into the ground, but you must make sure that the container is in direct contact with the material or metal. The third way for controlling static electricity is by using non-conductive material so that it will be rather hard for any static to build up in the containers. There are some problems with these techniques though. The first two methods are not reliable because a good connection between to metal surfaces is hard to maintain, and the third method has some problems too, certain types of containers might not be able to take heat or shock. There are some inventions made to make static electricity, like the Van de Graaf generator, AKA tin can generator, made by Dr. Robert Van de Graaf. This generator can generate some 100,000 to 10 million volts of electricity. Although this generator was made in 1935, it was not the first one. There were other static electricity generators like Von Buschs generator, which was made in 1893, and is a generator made with two pulleys and a belt running between them, which rubs on a charge collector comb inside and a sphere that has been insulated. Another static electricity generator is Roulands generator. Roulands generator was made in 1785, this generator has a ribbon running between two pulleys with a charge collector tube in the middle. These three generators can be used to see how much static can effect some certain types of materials. The three generators might not work in humid places because the water in the air might help conduct the static charges to a place where they can easily be taken in by positively charged ions. .u46b7353af1a5996c47656b900f7c14c7 , .u46b7353af1a5996c47656b900f7c14c7 .postImageUrl , .u46b7353af1a5996c47656b900f7c14c7 .centered-text-area { min-height: 80px; position: relative; } .u46b7353af1a5996c47656b900f7c14c7 , .u46b7353af1a5996c47656b900f7c14c7:hover , .u46b7353af1a5996c47656b900f7c14c7:visited , .u46b7353af1a5996c47656b900f7c14c7:active { border:0!important; } .u46b7353af1a5996c47656b900f7c14c7 .clearfix:after { content: ""; display: table; clear: both; } .u46b7353af1a5996c47656b900f7c14c7 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u46b7353af1a5996c47656b900f7c14c7:active , .u46b7353af1a5996c47656b900f7c14c7:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u46b7353af1a5996c47656b900f7c14c7 .centered-text-area { width: 100%; position: relative ; } .u46b7353af1a5996c47656b900f7c14c7 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u46b7353af1a5996c47656b900f7c14c7 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u46b7353af1a5996c47656b900f7c14c7 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u46b7353af1a5996c47656b900f7c14c7:hover .ctaButton { background-color: #34495E!important; } .u46b7353af1a5996c47656b900f7c14c7 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u46b7353af1a5996c47656b900f7c14c7 .u46b7353af1a5996c47656b900f7c14c7-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u46b7353af1a5996c47656b900f7c14c7:after { content: ""; display: block; clear: both; } READ: What I've Learned as a Foreign Exchange Student EssayLightning can be dangerous and may hurt you badly and even kill you if it gets to you, But all Lightning is, is a enormous charge of static electricity.

Constitutional Republic Essays - Politics, Veto,

Constitutional Republic Between 1787 and 1791 the Framers of the US Constitution established a system of government upon principles that had been discussed and partially implemented in many countries over the course of several centuries, but never before in such a pure and complete design, which we call a constitutional republic. Since then, the design has often been imitated, but important principles have often been ignored in those imitations, with the result that their governments fall short of being true republics or truly constitutional. The Framers of the Constitution tried very hard to design a system that would not allow any one person or group within the government to gain too much power. Personally, I think they succeeded. In order to guard against what one of the Founding Fathers called an excess of democracy, the Constitution was built with many ways to limit the government's power. Among these methods were separating the three branches, splitting the legislature so laws are carefully considered , and requiring members of Congress to meet certain criteria to qualify for office. The Founders did leave a few problems along with their system. Separation of power was very effective. The three branches of government (executive, legislative, and judicial) are kept separate, and each has different powers. Congress has legislative, or law making, powers. Legislative powers are further divided between two legislative bodies. The President has the power to carry out, or execute, the laws. Lastly, the Judicial branch had the judging power, used to interpret the laws. Some powers were delegated to the central national government, while others are reserved to the component states or the people. In addition, each branch is able to restrain or balance the powers of the other two branches upon abuse of their power. If the President is suspected of unlawful acts, he can be impeached, or tried by the Senate for misusing his power. The Senate has the sole power to try all impeachments. If he is found guilty, he can be punished but his sentence can be no more than being thrown out of office and being forbidden to hold any government office. Furthermore, if the President wants to spend money, his request must pass through Congress, since it has control over spending. Lastly, Congress can re-pass a bill that was vetoed by the President. Congress also has checks and balances against itself. The President can veto a bill from Congress, and although Congress can override a veto, obtaining a two-thirds vote to do so is very difficult. Public speeches by the President may also concern the public with an issue, putting pressure on Congress to act upon it. The Judicial branch exerts control over the other two by deciding whether or not actions made by the President or Congress, i.e., laws are constitutional . The limitations on and difficulties of passing laws are very, very important. The split legislature creates a more complicated maze through which laws must find their way before being passed. First, a law must be introduced in either the House of Representatives or the Senate, the former having sole power to introduce laws concerning revenue. After the law is introduced, it must be approved by the other house, who may agree with, amend, or discard the law. Once both houses have agreed on the law, however, the President must approve it. If he does not, he may also amend it and return it to its originating house for reconsideration. If both houses then agree on the amended bill by a two third majority vote, it can be passed. The bill also becomes a law if the President does not return it to Congress within ten days (except Sundays) of his receiving of it. The labyrinth of Clerks, which is not even mentioned in the Constitution, makes law passing far more difficult, resulting in only th e passing of laws that have been extremely carefully considered. The reason that Congress is careful is because they are responsible for deciding matters that will have a great impact on the country. The President is able to make decisions quickly in order to react to urgent matters in a timely fashion, for example, not too long ago, Bill Clinton ordered an attack on Afghanistan, it

Antonio is Alienated essays

Antonio is Alienated essays I believe that in the novel Bless Me, Ultima Antonio is an alienated individual. He doesnt seem to act like any of the other kids his age and has been through so much more then they have. For example, Antonio is torn between making his mother happy and becoming a priest, or making his father happy and becoming a cowboy type figure. He also has experienced a lot of death in his life to people he cared deeply about. I believe that Antonio is alienated because he has the mind of an adult, he is the only one who can talk to Ultima, and he can see the future. Oddly, Antonio is the only one who understands Ultima. For example, in the beginning of the book Antonio shook Ultimas hand and he could sense the power of a whirlwind pass through him. Also, Ultima declares that only she will know what the future holds for Antonio. In the novel I noticed that Ultima rarely talks to anyone except for Antonio, he probably possesses something that no one else has. Sometimes Antonio and Ultima would work out in the garden and talk about what is going on in Antonios life. This makes me think that Antonio has some sort of special powers like Ultima if they understand each other so well. Throughout the book, Antonio has many dreams and some of his dreams tell about things that happen in the future. His dreams often foreshadow into whats going to happen in the next chapter. For instance, Antonio dreams of his brothers returning home from the war and the next day his brothers came home. Antonio also dreams that the owl flies the Virgin of Guadeloupe and all the babes of Limbo go to heaven. This power that he possesses is not human like and is considered abnormal. For some reason Antonio could see the golden carp even though he was mature mentally. Only kids are supposes to be able to see the golden carp. Childrens minds still believe in things such as the golden carp, so Antonio has ...

Questions-Communication Essay Example | Topics and Well Written Essays - 1000 words

Questions-Communication - Essay Example Diversity within an organization can take a number of different forms such as diverse cultures, religions, nationalities and job groupings (Shockley-Zalabak, 2002; Mor-Barak, 2011). In my organization, the implementation and maintenance of programs that value diversity is generally undertaken using a number of approaches, key among them is review and re-writing of policies so as to create a division within the organization tasked with prompting inclusion and workforce development (Mor-Barak, 2011). This division is mandated to undertake a special recruitment policy that is designed to seek to promote diversity within the organization. To this end, training programs are conducted to promote the adoption of diversity among the employees. The division also implements a variety of internal mentorship and internship programs that are designed to prepare some of the internal candidates both for competition with outside job applicants and upward mobility to prevent their being marginalized by the special recruitment program (Mor-Barak, 2011). The diversity valuing programs practiced by my organization are seen to be quite effective at increasing both the awareness and valuing of diversity in the workplace. They are designed to increase the organization’s diversity via the special recruitment policy while simultaneously promoting the competitiveness of the existing employees through the internal mentorship and internship programs (Mor-Barak, 2011). However, there are a number of changes that can be made to increase the overall effectiveness of these programs. While increasing the awareness and integration of diversity within the organization is seen to be primarily dependent on employees at every level of the organization working at fulfilling their roles, it is also critically important for the organization’s leadership to increase both the amount of resources and the level of guidance and support it lends to these programs (Mor-Barak, 2011). Reference: Mor-Barak, E. M. (2011). Managing diversity: toward a globally inclusive workplace. Los Angeles: SAGE. M4A1: The communication style used by a past leader in my organization, its relation to his leadership style and its suitability to our workplace and culture When I joined my organization, my direct supervisor primarily used to employ the use of an assertive communication style. His role of directing the new recruits on how to perform their duties necessitated that he used the style to ensure that he was able to portray himself to be in authority when working with the recruits (Shockley-Zalabak, 2002). The assertive communication style is seen to have been quite appropriate to the supervisor a suitable to our workplace as it perfectly complemented his transactional leadership style. In line with his leadership style, the manager used to provide us with a number of pre-agreed tasks to perform and would then punish or reward us depending on how these tasks were performed (Shockley-Za labak, 2002). In the event that one of us would continually fail to adequately perform the assigned task, the supervisor would then undertake to provide more intensive and closely supervised training to the employee and would then encourage the employee by providing the employee with bonuses if they managed to register performance improvements. However, the communication style used by the supervisor could have been drastically improved if the supervisor undertook to try and listen more to the input provided
