Solenoids – Physics coursework

Solenoids Permanent Magnet- Magnetic Field.http://www.diracdelta.co.uk/science/source/m/a/magnetic%20field/source.html Magnets have two poles called North and South.Similar (like) magnetic poles repel. Unlike magnetic poles attract. A magnet attracts a piece of iron. The most important of the two properties of attraction and repulsion is repulsion. The only way to tell if an object is magnetised is to see if it repels another magnetised object. The strength and direction of a magnetic field is represented by magnetic field lines. Field lines by convention go from North to South. A magnetic field is three-dimensional, although this is not often seen on a drawing of magnetic field lines.Electromagnets A magnetic field exists around all wires carrying a current. When there is no current the compass needles in the diagram shown line up with the Earth's magnetic field. A current through the wire produces a circular magnetic field. See what happens when there is a current in the wire. The magnetic field for a coil of wire is shown below. The magnetic fields from each of the turns in the coil add together, so the total magnetic field is much stronger. This produces a field which is similar to that of a bar magnet. A coil of wire like this is often called a solenoid.http://www.bbc.co.uk/bitesize/standard/physics/using_electricity/movement_from_electricity/revision/1/slideshow-1/2/An electromagnet consists of a coil of wine, through which a current can be passed, wrapped around a soft iron core. This core of magnetic material increases the strength of the field due to the coil. ‘Soft’ iron is easily magnetised, and easy to demagnetise- it does not retain its magnetism after the current is switched off. Steel, on the other hand, is hard to magnetise and demagnetise, and so it retains in magnetism. It is used for permanent magnets. The strength of an electromagnet depends on:The size of the current flowing through the coil The number of turns in the coil The material inside of the coil Heinmann physics Domains – http://hyperphysics.phy-astr.gsu.edu/hbase/solids/ferro.html#c4Ferromagnetic materials exhibit a long-range ordering phenomenon at the atomic level which causes the unpaired electron spins to line up parallel with each other in a region called a domain. Within the domain, the magnetic field is intense, but in a bulk sample the material will usually be unmagnetized because the many domains will themselves be randomly oriented with respect to one another. The main implication of the domains is that there is already a high degree of magnetization in ferromagnetic materials within individual domains, but that in the absence of external magnetic fields those domains are randomly oriented. A modest applied magnetic field can cause a larger degree of alignment of the magnetic moments with the external field, giving a large multiplication of the applied field.FerromagnetismIron, nickel, cobalt and some of the rare earths (gadolin ium, dysprosium) exhibit a unique magnetic behavior which is called ferromagnetism because iron (ferrum in Latin) is the most common and most dramatic example.

Monster Walter Dean Myers

Monster, by Walter Dean Myers, is about a 16 year old Harlem boy named Steve Harmon. Steve gets tried for murder in a court of law because he supposedly was involved in the burglary/shooting of Mr. Nesbit, the convenience store clerk on December 22. Steve is wrongfully arrested, and spends time in jail awaiting his verdict, which he is found innocent for after a long trial. While in prison, Steve put his time to good use and wrote a play word for word based on his trial. This book falls under the theme of stories that expose limits. This is true because Steve lost all hope in his case, and thought that he will be found guilty for the murder of Mr. Nesbit; however he found thestrength to push through and regain his confidence. Steve's main inspiration was his family because he does not want to look weak in their eyes, especially his younger brother. In addition, Steve has to live in prison for a few months awaiting his verdict; he has to keep up a tough attitude to get through the daily occurrences of beat-downs, molestation and corruption. Prison is even worse for an inmate when they are truly innocent. Steve Harmon is a very strong individual for being able to push through this whole trial without going over the edge; he coped with everything and kept sane by writing his play. Steve Harmon portrays the fear of a teenager who is in prison and portrays a confident teenager who is strong enough to pull through any adversity while having his world thrown upside down. He portrays fear of ones life in prison because the whole book he is trying to get out of prison and to have his life back. He also convinces his lawyer of his innocence and the fact that he was simply in the wrong place at the wrong time. If Steve Harmon had not put any effort in, or did not convince his lawyer he was innocent, he would have rotted for his whole life in a 6 by 8 foot cell. Steve Harmon portraysconfidence because he always believed in his innocence, and would stop at nothing to convince others. Steve's family and lawyer, Kathy O'Brien, motivated Steve to believe in himself because they believed that he could never commit a heinous crime such as murder. I can relate to Steve Harmon because when I was elementary school I did not have much confidence in myself. For example, when I would be in plays I did not like to be on stage and perform. When Steve started his trial he didn't have muchconfidence in himself either. Steve Harmon had such little confidence he thought he was guilty even though he was not. As time progressed, I felt much more confident in myself to take certain risks, try new stuff and make my voice heard. I can thank my parents and friends for this accomplishment. My parents would always encourage me to try new things, speak out, and always tell me I am the best. Steve Harmon gained hisconfidence from his friends and family also, his lawyer always telling him he is going to be ok and he will be tried innocent. What this taught me about myself is family is the most important thing in your life and they can only make your life better.

Strategic Financial Management - Coursework Example However, among all these objectives, the main one for business organisations is supposed to be an increase of the value to its shareholders. In this case, the bid to maximize the wealth of its shareholders becomes a fundamental goal of management. It is important to note that investors often anticipate earning satisfactory returns from the investments they establish in the firm. Shareholders are the actual owners of the business, which means that senior managers are have a responsibility to ensure maximisation of investor’s wealth, not just for the success of the business, but also for continued investments, thus gaining the ability to increase its market share and financial position. Maximizing this wealth can be determined by the payout of dividends as well as capital gains through an increasing market value for a particular share price of the business. In the process of achieving this objective, conflicts can sometimes arise in the business. In this case, business managers may end up making decisions based on their interests and not achieving the investors’ wealth. Therefore, traditional view is that profit maximization needs to be made the ultimate goal and objective for the business. Financial managers are often involved in managing cash flows on behalf of the companies they work for as well as their respective owners. In any firm, financial management is often concerned with the process of making decisions in three main areas, which include; investing, financing as well as dividend policy. In all these, wealth maximization always remains to be the fundamental goal for the firm. Business managers are expected to ensure that they effectively manage the stock prices for the benefit of their respective shareholders since they are needed towards increasing the financial muscles for the company so that it can achieve its other objectives (Kaen 2003, 87). In this case, the criticisms raised against this

Same-Sex Marriages Should be Legally Recognized Essay

Same-Sex Marriages Should be Legally Recognized - Essay Example Those people have to be given the possibility to legalize their relationships. As the relationship between gays and lesbians don't have any legal definition, and they aren't regulated by the government, those couples are left to se the parameters of their partnership by themselves, which sometimes has negative consequences, as Dorothy Pomerantz notes in her article about the legalization of the same-sex marriages published in The Advocate in 2000.1 Marriage has always been an important institution in the American society, as after tying the knot two people became able to make important decisions for each other, and the share the common responsibilities. For the U.S citizens marriage means that two people decided to share their money, resources, and responsibilities as well as their bed, a legal commitment made to the society. Almost any man and any woman in our country can register a marriage, despite of their age, social status, or their feelings towards each other. The few things that are needed to register an official union is being the representatives of the different genders, and being more or less mentally healthy. In the same time, two people who love each other, and want to share their lives, and, maybe, raise children together, are deprived of the possibility to legalize those intentions just because they are of the same gender. Eric Stoltz, the author of the article about Proposition 22, a law project that banned recognition of the same sex marriages in California, writes: I could, for example, fly to Las Vegas tonight, wed a prostitute in a drunken stupor, and return to Los Angeles tomorrow morning to have my marriage fully recognized by the law and society. Fifty women can vie on national television to marry a man they've never met for his money, and that union would be recognized by the state. Any man can marry a woman for her looks in a cynical but legally sanctioned form of concubinage, and that union would enjoy all the rights and privileges of marriage. But if two people of the same sex want to establish rights of inheritance or become legally empowered to make health-care decisions for one another, we are now told that the entire structure of Western civilization will come crashing down. (Commonweal, 2000).2 And, in fact, the situation indeed looks like it. The persuasion that marriage should be a union, which only the representatives of two different genders can enter, is a social norm that was established thousands of years ago, when people created families as they needed to unite in order to survive, and bring their children up. The social roles in the primitive society were very well-defined - men had to bring food, and women were to raise kids and maintain fire, thus such a union was perfectly justified (Sullivan, 2004). 3 As thousands of years passed after people left the caves, the distribution of social roles has changed. Today both men and women can be the breadwinners in the family, the same as both members of the family can stay home to care for the kids. The necessity in the different-gender unity nowadays is much weaker than it had been when this social norm was first formed.

Find two articles that are influential in the field of Organizational Development - Essay Example In this aspect, our major goal is to expand into the regional market. A major threat to our business has been the influx of cheap imports and the rise of competitors. Brainstorming has helped in achieving a technique in problem solving and team building since it creates new ideas, solves problems, motivates, and develops teams (Bushe & Marshak, 2009). The article provides readers with information pertaining to internal practices that ensure the success of an organization. An alternative method is the nominal group technique that encourages contributions from everyone. This ensures participation of all the group members, especially of people who think best in silence and for some members who are, thanks to this technique, more vocal and are not overshadowed by others (Nguyen, 2007). Motivating the employees is a good leadership practice. Motivation involves implementing an innovative reward system directly with the workforce. Development programs assist an organization in bringing up a clear understanding of the growth of an organization. Leaders are always under a lot of pressure to guide and direct their subjects or employees to achieve the set goals. For effectiveness in leadership, leaders have to adopt strategic leadership. Strategic leaders are leaders who are proficient in motivating and persuading people to acquire the vis ion of that company or institution. Strategic leadership is about managing the employees by using strategies of management in order to achieve set goals. Apart from expressing a strategic vision, strategic leaders should also be able to create an organizational structure for the business, which is an extremely crucial part in strategic leadership (Nguyen, 2007).

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

Poetry - Essay Example The poem â€Å"God’s Will for You and Me† by an unknown author seems to be written for the gentle of spirit, almost childlike in its’ innocence. The dominant theme running throughout is one of goodness. In an effort to impress upon the reader the importance of being a good person in order to carry out God’s will, the author hopes to set an example of ways to be to do so. The ending few lines impart to us a way to be faithful to his will itself. The mood is both cheerful and hopeful, as the reader may be inspired to act in such a way as to find favor with the Lord. Love he states should be the daily motivating influence. The Title â€Å"God’s Will for You and Me† is itself the message throughout the poem and is significant because of what it represents. It is quite a feat to live by God’s Will and the poem is daring in its’ desire to impress upon us the necessity of doing so. The motif throughout is further amplified by the sweetness of what is being said and by the many literary devices the author uses. The definitive stance the author has adopted is a way of being good in order to carry out God’s will. The mental and emotional disposition of goodness lends itself to an atmosphere with the same feeling. We feel gentle and sweet when reading it because of the sentiment so ably illustrated with the choice of words. The tone achieved is instrumental in evoking an appropriate inspirational feeling from the reader. We are compelled to act accordingly after imbuing the essence of the innocent sentiments expressed. The poem seems to be written almost as a stream of consciousness with an uninterrupted flow of thoughts and ideas. Here we see the author’s thinking process as a unified idea carried out. Flowing from one thought to the next, we see illustrated a number of ways we can model ourselves and our actions to carry out god’s will. Being â€Å"gentle and kind†, â€Å"merciful and mild† and â€Å"just to be cheery when things go wrong† are all things we can aspire to. The poem reads as a narrative of the author’s thoughts instead of a dialogue with the reader. A feeling of verisimilitude is created as we listen to the lofty ideals expressed in the poem. The lines are stated so matter of factly as to be true. They are structured as sentiments but sound almost like commands. With the influence of God written into the piece we can trust that this is the way to be. It seems to be an allegory for a grander concept. Simply stated, each line and sentiment sp eaks to us of being good. Gentle, kind, merciful, all speak to us about the teachings of the church. As we read the examples of good behavior we can sense the higher aspirations we can ascribe to. In hoping to carry out God’s will we can all benefit ourselves by living our lives in such a way. It is further stated that this is the way God wants us to be and we the devout can take comfort in this, hoping to be pleasing to the Lord. Rhyme and Rhyme Scheme â€Å"God’s Will for You and Me† is written in such an innocent way and almost seems to be addressed to a child. With the use of alliteration it has the quality of a nursery rhyme in both the internal rhyme and the rhyme scheme. It is actually a sonnet. Sonnets are often sweet

None - Essay Example Precisely, the Toyota Prius sold many vehicles to over eighty nations. The advertisements and word of mouth has influenced the demand for the Toyota Prius. The iPhone competes with the increasing alternatives, and the prices have dropped. The distribution of the iPhones has intensified, and the products are available in different parts of the globe. The adverts in maturity stage focus on promoting the product by influencing the consumers to increase the purchasing power (Cant et al 242). Fundamentally, the adverts aim at creating a competitive edge in the ever-competitive market through a differentiation strategy. The iPod advert is an excellent example of product in the decline stage of life cycle. With introduction of new products, iPod sales have decreased. Similarly, a notable decline of interest from the consumers and retailers is evident. Maximum competition has occurred leading to negative sales growth, as well as, lower profits. Cant et al argues that stagnation characterize the decline stage of product life cycle
