Fluorescent Light Science Experiment

Fluorescent Light Science Experiment Learn how to make a fluorescent light glow without plugging it in! These science experiments show how to generate static electricity, which illuminates the phosphor coating, making the bulb light up. Fluorescent Light Experiment Materials fluorescent bulb (tubes work best. Its okay if the light is burnt out.)Any of the following:Saran wrap (plastic wrap)plastic report folderpiece of woolinflated balloondry newspaperanimal fur or fake fur Procedure The fluorescent light needs to be perfectly dry, so you may wish to clean the bulb with a dry paper towel before starting. You will get brighter light in dry weather than in high humidity.All you need to do is rub the fluorescent bulb with the plastic, fabric, fur, or balloon. Do not apply pressure. You need friction to make the project work; you dont need to press the material into the bulb. Dont expect the light to be as bright as it would be plugged into an outlet. It helps to turn off the lights to see the effect.Repeat the experiment with other items on the list. Try other materials found around the home, classroom, or lab. Which works the best? Which materials dont work? How It Works Rubbing the glass tube generates static electricity. Although there is less static electricity than the amount of electricity supplied by wall current, it is enough to energize the atoms inside the tube, changing them from a ground state to an excited state. The excited atoms release photons when they return to the ground state. This is fluorescence. Usually, these photons are in the ultraviolet range, so fluorescent bulbs have an interior coating that absorbs the UV light and releases energy in the visible light spectrum. Safety Fluorescent bulbs are easily broken, producing sharp shards of glass and releasing toxic mercury vapor into the air. Avoid applying a lot of pressure to the bulb. Accidents happen, so if you snap a bulb or drop one, put on a pair of disposable plastic gloves, carefully use damp paper towels to collect all the pieces and dust, and place the gloves and broken glass in a sealable plastic bag. Some places have special collection sites for broken fluorescent tubes, so see if one is available/required before putting the bulb in the trash. Wash your hands with soap and water after handling a broken fluorescent tube.

Inflation Essay Example | Topics and Well Written Essays - 750 words

Inflation - Essay Example Inflation is defined as the rise of the level prices of goods and services in a given economy over a certain period of time. In the event of an inflation or the rise of prices of goods and services in a given economy, the purchasing power of a given currency is diminished to the effect that it will now require more units of money for the same goods and services purchased or the number of goods and services purchased with the same amount of money is reduced. In effect, inflation is the loss or the diminishing of value of money in a given economy (Blanchard 45). In plain language, inflation is the instance where goods and services get expensive or the phenomena where people complain that the price of commodities is rising. Concretely, if one unit of bread costs $1 before and it now costs $2 for the same unit of bread, the increase in price can be attributed to inflaction. Inflation is typically measured by comparing the annual change in Consumer Price Index (CPI) or the basket of goods that people normally buy over time. The effect of inflation can either be good or bad. Inflation has the effect of decreasing the net value of money because of the rise of the price of commodities. For example, the $1,000 savings this year may only have the purchasing power of $900 next year due to rising prices caused by inflation. This is not good for investors and consumers alike. For investors, this meant that the inputs for production will increase substantially over a short period of time and this could make the business uncompetitive because it has to pass the increase of the price of its inputs to its selling price making it more expensive than its competitors. For the consumers, it makes their lives difficult because their money cannot buy much goods and services and in extreme cases, excessive inflation, such as the case of hyperinflation can drive consumers to hoard goods to shielf themselves from excessive increase of prices causing shortage of goods. Inflation is gener ally caused by several factors. In the case of hyperinflation, it is typically caused by too much circulation of money or excessive money supply (Barro and Grilli 139). This meant that more money are printed and circulated for the same amount of goods and services that it now requires more money to buy the same goods and services. The classic example for this is the phenomena of the Mickey Mouse money in the Philippines during the Japanese occupation whereby the Japanese government issued Japanese peso in excess. The amount of money that was circulated was just too much that the currency was Mickey Mouse Money or play money because it became worthless that buying a mere loaf of bread requires a bag or case of money (Dijamco). Another common factor of inflation is the change either in demand or supply of goods and services. A sudden increase in demand of a certain goods or services can drive the price up given the same unit of supply (law of supply and demand, prices go up when deman d goes up). In the same vein, a contraction in supply can also result in inflation or the increase in price of commodities. The classic example for this is the decision of Organizationof Petroleum Exporting Countries (OPEC) to increase oil price in October of 1973 where the the increase of the world price of oil shot up as much as much as five times and backed by a selective embargo which was directed against the industrialized countries, Latin America and developing countries (Street, 1978). OPEC’s decision to increase the price of oil contributed to the recession of the US economy in 1974 to 1975. Another common cause of inflation is the excessive growth of money supply compared to rate of real economic growth (Mundell 280-283). For example, if an economy only produces an amount of goods services to $100 a year and yet it continues to print and circulate money to the amount of $150, it will naturally cause prices to go up because there are too much money circulating in the economy. Inflation however can also be good when its

Finance Ethics Essay Example | Topics and Well Written Essays - 750 words

Finance Ethics - Essay Example We shall address their views regarding such decisions and issues. Ford deals in automobiles that find a market all over the world. The success of the company is dependent on a number of stakeholders as viewed from the perspective of production of the end product. All stages of production call for integration of a couple of elements that move in the same direction (Preston, 1995). Employees are key stakeholders in this company. They feature in various departments and segments of the organization. Production process would need personnel in the form of engineers and technical experts. There would be a need for administrators, marketers, assistant managers and a whole range of other staff members. The organization would have to steer them towards achieving goals of the organization without ignoring other stakeholders (Preston, 1995). Financiers of the company are in the form of banks and shareholders. Their role is key in having the entire company on its feet. Hiring of personnel, making purchases from suppliers, marketing, and advertising are all dependent on funds generated and availed by suppliers. Another key stakeholder of this company is the target customer. The company has a moral duty to have their needs first by providing quality automobile and after sales attention. Their opinion and regards about the item bought is an area of concern for the buyers. Their suggestions define the success of the company (Harrison, 2010). Suppliers to Ford Motors complete a segment of the success puzzle. They avail resources to the company for the production process. Structural materials in the form of tires, metallic items, and other requirements make production happen. Ford Motor Company thrives in a community that is on its receiving end of the matters that come with production. The company has to be a good citizen to execute production responsibly. Governmental bodies have a stake

CBRN Chemical Biological Radiological Nuclear weapons Essay - 4

CBRN Chemical Biological Radiological Nuclear weapons - Essay Example in the fields of nuclear science and technology, a wide range of destructive weapons have been introduced that can be used to cause massive destruction in the targeted areas. If we talk about the United States of America, we can say that the United States has been on the red list of the terrorists for a long time because of its efforts towards establishing and stabilizing democracy and peace in the world. This paper includes a discussion of nuclear weapons as the weapons of mass destruction, as well as some non-state actors that pose this threat. Along with this, the paper also includes a discussion on the ways this threat can be mitigated by the government of the United States in the event that suspected states actually make an attack. The thesis statement for this paper is that ‘there is a continuous threat of the use of nuclear weapons by Al-Qaeda (non-state actor) and Iran (state actor) against the forces of the United States; hence, a well-planned strategy should be followed to mitigate the potential threat’. The type of weapons of mass destruction to be discussed in this paper is nuclear bomb. Nuclear bombs have been the most deadly weapon of mass destruction since their development. These bombs have been used against Japan during the Second World War in the cities of Hiroshima and Nagasaki causing thousands of casualties. The countries that possess these weapons include the United States of America, the United Kingdom, Russia, France, China, North Korea, India, and Pakistan. Among all these states, Pakistan is considered the most risky nuclear state because of presence of Al-Qaeda terrorist group and some other extremist and terrorist groups in the country. Pakistan is also one of those states that have not signed the Non-Proliferation Treaty (NPT) that ensures the peaceful use of nuclear energy. Moreover, the large-scale presence of Al-Qaeda in the region makes Pakistan the most risky and dreadful nuclear state of the world that can pose severe

Corporate Social Responsibility - example of a specific organization Essay

Corporate Social Responsibility - example of a specific organization that is building the future urban configuration of cities - Essay Example In Australia, air pollution costs are already very high. Human costs of health are estimated are approximately A$3 billion to A$5.3 billion each year with annual damages to materials, buildings, and property at between 3 and 5 billion Australian dollars, which is 1% of GDP (Ercoskun, 2012: p33). The biggest cause of pollution in the country is cars. Since most people in Australia do not use public transport and are reliant on their cars for transport, the country is among the highest polluter, per capita, in the world. Urban designs have a powerful impact on the quality of air, as well as exposing the population to pollutants. This results in most cities becoming unsustainable, both environmentally and economically. As pollution increases, living in these cities become worse. Most people in Australia have accepted driving to work over long distances and urban sprawl as a way of life. However, this may change because of the threat to supply of oil and increase in its price, enhancemen t of the greenhouse effect, and threat to their health because of poor quality of air (Gibson, 2011: p51). CSIRO has examined various alternatives in the evaluation of their capacity to reduce atmospheric pollution like emissions of greenhouse gases and energy consumption. In the past, similar inquiries have had their basis on subjective assessments concerning city planning and its impact on energy consumption and air quality. However, the magnitude order between various types of city structure has not undergone evaluation in many places, in the world. Integrated air-shed models, transport emissions, and land use that use advanced urban design software and spatial planning assisted researchers in the exploration of the effects that alternative transport, workplace, and residential structures could have on consumption of energy and urban air quality to 2011 (Gibson, 2011: p52). CSIRO examined six alternative future urban scenarios. The first was business as usual with extrapolation o f the current patterns to the future, which are dispersed, low density, and laissez faire. The second alternative was edge city with increased housing densities, population, and employment at elected nodes in the city, as well as increased investment that link edge cities via orbital freeways (Gibson, 2011: p55). The third alternative was corridor cities that focus on linear corridor growth that start from the CBD with support from upgraded public infrastructure. Fringe cities are the fourth alternative that involves additional growth that predominates on the city fringes. Finally, ultra cities involve additional growth that is predominant in provincial cities that lie within 100 km of the capital and are linked via high-speed trains. These urban configurations were applied by CSIRO to Melbourne City based on increased populations from 2.5 to 3.0 million by the year 2013 (Gibson, 2011: p56). Key assumptions in this included increment of residential density, a full uptake of controls of vehicle emissions, a varying ratio concerning private and public transport, and an increase in telecommuting, in specific industries. The results were dramatic in how they impact on quality of urban air. There are several worst-case scenarios identified by CSIRO. Photochemical smog can possibly decrease by 55%

Movie 1408 Essay Example | Topics and Well Written Essays - 750 words

Movie 1408 - Essay Example In his famous book on theory of Montage, â€Å"The Film Sense†, he elaborates this process of words turning into images through representations, quoting the poems of John Milton and Mayakovsky. â€Å" Mayakovsky doesn’t work in lines , he works in shots† ( Word and Image --- The Film Sense – sergei Eisenstein –page 62-63 } When a well read story ( or poem ) comes into light as visual images on the big screen as a film, it tends to disappoint the above said readers of the story. For the images on the screen will never match with the images, the above said reader carries with in him/ her self, of the story. Stephan King’s style of writing is such that, he draws out the horror slowly. He never allows the reader to plunge head long into the horror. This style of writing, gives more space for the reader’s imagination and thus for the â€Å"Cinematic Recreation† within himself. Thus Stephan King remains a tough writer, for any film ma ker. More over, short story is often considered to be the ideal literary form for depicting horror. Many writers consider it difficult to maintain the feeling of horror in the reader, over hundreds or more pages, that a novel as a literary form demands. The issue gets multiplied when one tries to make a film out of a horror short story. One faces the risk of ending up with a movie with lots of good patches of horror, but padded up between with lots of dead spaces. It is the absence of such dead spaces that makes Film makers like Alfred Hitchcock and Claude Chabrol, the masters of horror films. One technique used by the Swedish director Mikael Hafstrom, ( who made the film â€Å"1408†,based on Stephan King’s short story by the same name ,in 2007 ) to over come the above said problems of cinematic recreation of the images of the short story, is to confine the space of action of the film to a single hotel room. This gives scope for concentration of the

New Business Proposal Essay Example | Topics and Well Written Essays - 1000 words

New Business Proposal - Essay Example kit, 2011). The product is targeted towardsa customer base that has concern for the environment, and wants to contribute to its wellbeing by reducing their eco/foot print impact etc. The product is also expected to do well in the market because of its uniqueness and the fact that no online retailer has done this before. The detailed marketing strategy of the product has been discussed as follows: Product Strategy: The reusable and recycled bags are to be made of both recycled cotton and plastic materials. The brand awareness of ASOS will be relied upon as one of the key competitive advantages. Along with that, the good relationships of the ASOS brand with the suppliers and the high purchasing power that it has will also serve as a plus for the awareness and promotion of these bags. Another key aspect that would greatly benefit the product would be that of first mover advantage as up till now no online retailer has come up with this sort of idea. The bags will be made available to the markets of the UK and Ireland only. These bags would be large in size so as to serve for accommodating things for multiple purposes (posting, usage etc.) and they would have the ASOS logo on them. A specific percentage of the revenues generated would be granted to charities so as to better create an impact in terms of working towards the collective good of people and the overall society. The product is to be similar to Anya Hindermarch’s ‘I am not a plastic bag’ concept that encouraged people not to use plastic bags (Winterman, 2007) with a number of customized touches added to it. These would include a more stylish outlook, larger size that is to add to its value in terms of convenience, and finally, because of its outlook and size, these bags would be multipurpose serving the purposes of both shopping and delivering. The bag would also have specific customer number ID on it which would allow bag tracking/identification. The bag would be designed as such that i t would ensure maximum protection of the clothes etc. placed in it. The bags would say, â€Å"Yes I shop at ASOS because I carry their delivery envelope shopping bag†. Once, the product has established itself in the market, the producers can even go on to offer a variety in the colours and styles being offered and can eventually go on to offer customization options as well to grab all the more market share. Pricing: The pricing strategy has been decided to be cost based pricing in which the price is set in accordance to the production costs inculcating costs of goods and fixed assets plus a specific amount of profit margin (Allen, 2012). On that note, the price of the bags has been estimated to be in the bracket of about ?2.00 or 2.50 as a certain percentage of the revenues would also be going to some welfare cause or charity and hence that would also be kept under consideration while setting the final price. Place: The bag would be produced and supplied by a supplier with th e design accustomed to ASOS brand. Special trainings would be given to the logistics team in terms of identifying the bag, instructions on usage of the bag, dealing with lost or damaged bags (small charge, goodwill replacements) and in terms of teaching customers on how, why and where to use the bags. Promotion: The
