Electric Charge :: essays research papers

In some Greek experiments, objects attracted each other after rubbing. Other experiments produced objects that pushed away, or repelled, each other. The evidence showed that electric force made matter either attract or repel other matter.   Ã‚  Ã‚  Ã‚  Ã‚  Electric force is caused by electric charge. Electric charge is a property of the bits of matter within atoms. Electric force can cause matter to attract or repel because there are two kinds of charge – positive and negative charge.   Ã‚  Ã‚  Ã‚  Ã‚  The effects of electric force can be summarized as the law of electric charge: Pieces of matter with the same kind of charge repel each other. Pieces of matter with the same kind of charge attract each other. 2 objects with a positive charge repel each other, as do 2 objects with a negative charge.   Ã‚  Ã‚  Ã‚  Ã‚  Most objects are made of matter with equal amounts of positive and negative charge. Objects with the same # of positive and negative charges are electrically balanced, or neutral. Electric force is observed only when the balance of charge on objects is disturbed.   Ã‚  Ã‚  Ã‚  Ã‚  An electric charge on an object that causes the object to attract or repel other objects is called static electricity. The adjective static describes something that does not move. Charges on an object are called static electricity to contrast then with the moving charges in an electric current.   Ã‚  Ã‚  Ã‚  Ã‚  How can you disturb the balance of charge on objects so they exert electric force? The easiest way is the same way the ancient Greeks did it – by rubbing the 2 objects together. Rubbing neutral objects together allows charged pieces of matter to move from one object to another.   Ã‚  Ã‚  Ã‚  Ã‚  The invisible bits of negatively charged matter that move between objects are called electrons. The words electron, electricity, and electronics all come from the Greek word for amber – elektron. The transfer of electrons explains the electric force that attracts the balloon to the wool. Rubbing the neutral balloon with the wool cloth allows some electrons to leave the wool and stick to the balloon.   Ã‚  Ã‚  Ã‚  Ã‚  Neutral objects, like the balloon and the wool, become positively or negatively charged when their charges are disturbed. When an object becomes charged, no new charge is created; charge is simply moved around. This observation has been tested many times and is always true. It is stated a scientific law. The law of conservation of charge states all electric events occur by rearranging or moving charge.

A Fortune

Well at least according to his mother, the lady with a black gig, using most of her time crying, because she fears the narrator will grow up and be like his father. Growing up in a trailer park, the family didn't have a lot of money. This is one of the reasons for his father teaching him pick pocketing in the age of five. This pick pocketing is still a part of his life, even after his old man left town without leaving a note or a phone call. The reason for him still pick pocketing lies in the hope he has, of his father someday returning: â€Å"One day Pop will show up again.I'll hand him the boxful of money, he will throw me some bills, and then Ill Just stow them way without counting them. That's what I think. † (Line 31) It's not that he needs the money. In fact he has a Job. But he Is longing for the recognition from his father. As he says himself, when arguing why he didn't ever count the money his dad gave him: â€Å"l Just didn't want to know how much Pop thought I was worth. † (Line 13) When working his Job, he earns enough money to take Sundays of. It's not to go to church, but to recharge his batteries.Not being religious is something he learned in his childhood. His uncle Barney used to come around dressed like Santa, only to lose his eared and ask for at stiff drink. That taught him to be realistic, only to believe in what you can see yourself. Though not having had the most love full childhood, he still loves his mother: â€Å"l have to give her credit for trying to make me an honest boy. † (Line 1 5) He still visits her at the trailer park, reading the notes from fortune cookies aloud to her. When speaking of the fortune cookies, these play a big part In his life.He always saves them, after eating a low-price dinner at the Chinese restaurant. As he says: â€Å"I love those stupid fortune cookies. † (Line 38) When using â€Å"love† and â€Å"stupid† in the same line, he contradicts himself. The fortune notes inside the cookie are stupid, it's such a small thing, and the fortune usually doesn't come true. But he loves them, because when they tell him things like â€Å"love and happiness will be yours in abundance† it's something he has never heard before, it's something he hopes will come true.These fortune notes tell him everything he has longed hearing from his parents, the loving things they never told him. When seeing the little boy at the market, he reminds him of himself. The boy is about seven ears old, following his father, Just like the narrator at the age of five used to follow his father when they would go pick pocketing. When he sees the boy standing all alone In the street, he feels forced to take care of him: â€Å"l don't know what compelled me, but my feet Just sort of walked over to him before I told them to. Kid, you lost? â€Å"Do you want to come with me? † I heard myself talking and I swear I sounded Like a stinking Clapper. Eve never Ana a problem wi lt stealing wallets, D stealing lost kids is out of my territory. It's Just that, it must be nice, you know, to be mound† (Line 75) He feels a connection to the boy, which express itself in the last line. When saying it must be nice to be found, the narrator is no longer talking about the boy. He is talking about himself, and how he is longing to be found by his father. To be found, and being told that he is loved.When taking the boy to his house, the similarity between the two gets stronger. At first the narrator doesn't quite know what to do with the boy. But because of his loneliness, it's nice to have some company. He chooses to show his collection of fortune notes to the boy, and the two of them are paving a blast. The narrator never cries. But this boy touches something in him. When looking at his lop-sided smile, he gets all emotional. He has already given the boy a fortune note saying â€Å"time is of the essence, use it wisely,† when choosing to give all his fo rtune notes to the boy.Why? Here's why: mean it, kid. I want you to have my fortunes. You know why? You deserve it, kid, you earned it. † â€Å"Here it says, ‘Long life will be yours. ‘ I want you to have that one especially, because you deserve a long life† (Line 116) The narrator puts on the role of fatherhood, making sure that this id, opposite to himself, knows what he is worth and that he is deserves to have a good, long life. He is telling the boy the things that the father is supposed to tell him.By telling the boy what he is worth, he states the fact, that the boy is a fortune in himself – hence the title. His father is a lucky man, and he doesn't appreciate it. If he did, he wouldn't have yelled harshly at the kid when they were at the market. The text is build up as a flashback at first. The narrator is looking back at when he first saw the boy, then going on telling about his old childhood. When he's done telling about myself, he returns to the story: â€Å"Like I said, it was a Sunday when I saw this man and his son†¦ (Line 34) It goes on chronologically from here on, and the story ends sudden when the narrator has dropped the boy of at his house. The narrator is a 1. Person narrator, not knowing how other people know or think. By this kind of narrator, we focus on the narrator himself, although the main event of the story is the little boy. As fortunes being the main theme of the text, there's no talk about fortunes as a materialistic thing, but the fact that everyone is a fortune in themselves.But people aren't told, and it hurts the most when not hearing it from one's parents: â€Å"That guy didn't need his credit cards or cash or oilskin wallet. He didn't know what a fortune he had 159) Before meeting the boy, the narrator got a fortune cookie that said: â€Å"A change in your daily routine will lead you to treasure. † When telling the boy what he is worth, he immediately feels better with himself. The message of the text comes as a result of this: It's important to tell people what they're worth, no matter if they are rich or poor, leaving them happy and leaving you as feeling like a good person.

Med terms

By defining the word elements, one could define the medical words. Learning to combine and recombine the word elements into medical words is an integral component for those enrolling or practicing in the medical field. Word elements include prefixes, suffixes, and root or stem words. The stem or root word usually denotes the body part. Prefixes are placed before a root or stem word to modify the root or stem. Suffixes are placed at the end of a root or stem word to explain what is happening to the root or stem word. Below are examples of medical terms: Biology is the study of life and living things and bi/o means life; the o/logy means study of, when it is at the end of a word. Biolysis means the chemical decomposition of living tissue by the action of living organisms; lysis means decomposition, setting free, separation, destruction; thus, biolysis Cardiomegaly means enlargement of the heart; megaly means to enlarge; thus, cardiomegaly Neurotome means a fine knife used in the division of a nerve; -tom means to cut;-e means instrument (in this word) and/or noun marker; thus, neurotome. Pathoanatomy means the anatomical pathology; Path/o means disease, feeling, or suffering; thus, anatomy is the study of the structure of living organisms.[1] With the complexity of functions in the clinical area, it is imperative that a health care provider or those pertaining to the health team should know and understand these terms for easy accessibility and continuity of work. The use of medical terms has become the language in the clinical area, and so every health provider should understand in order to ensure that there is healthy communication between him and the client and within the health team. With the right knowledge and understanding of these medical terms, it is easier for the physician, or the nurse, or any health care giver to administer diagnoses and interventions and let the responsible subordinates carry out the task. The use of these terms is standardized which promotes integrity and clarity of information in the clinical area. Therefore, it is a must that there should be sufficient knowledge on these to promote optimum and faster delivery of care.

Comparing Linear Graphs Essay Example | Topics and Well Written Essays - 500 words

Comparing Linear Graphs - Essay Example However, in case of linear inequality graph, there will be more than one (infinite) value of y for one value of x. A linear equation graph can be easily plotted if some points (x, y) are known. Similarly, a linear inequality graph can be plotted if the points for linear equation of the linear inequality are known. The above two examples of linear equation and linear inequality have same expression (only difference is = and ≠¤ or ≠¥) and therefore can be plotted (graphed) similarly. If there are several linear equations than they can be plotted by choosing different colors, line types and size. Similarly, if there is more than one linear inequality (various supply and demand graphs) than for each linear inequality different types of color and shades can be used for differencing them. In addition, intersection (combined shaded area) of all the linear inequality will be solution area (for supply and demand graphs) and the points of intersection of linear inequality will be the break-even

Fair trade provides no significant benefits. To what extent do you Essay - 3

Fair trade provides no significant benefits. To what extent do you agree - Essay Example mplishments, the structure by which Fair Trade aspires to attain its objectives is severely weak, restricting its market opportunities and the value it gives to workers and farmers. As such, some claim that fair trade provides no significant benefits. This essay argues that Fair Trade does suffer from internal and external problems, but that does not mean that it provides no significant benefits. There is a wide array of criticisms about whether Fair Trade accomplishes its objectives of raising living standards for the most underprivileged producers and other players in global trade. Basically, there is a major problem at the core of the present development and achievement of Fair Trade (Cole & Brown, 2014). So as to achieve dominant presence and significantly influence the market, Fair Trade advocates have to collaborate with major corporate players. These corporate traders usually pursue clearly different objectives and usually reluctant or unable to totally commit themselves to Fair Trade principles (Smith, 2013). For instance, Starbucks’s dedication to Fair Trade principles has been criticised. A small percentage of Starbucks coffee was fairly traded in 2007, but its brand image or corporate reputation became known as socially responsible immediately after declaring its involvement in the Fair Trade system (Cole & Brown, 2014). Since Starbucks is the biggest global coffee retailer, it is in charge of buying larger volumes of Fair Trade coffee than any other vendor. Nevertheless, a meagre portion of its overall coffee is Fair Trade. The Fairtrade Labelling Organisation (FLO), tasked to give Fair Trade authorisation, was also criticised for not obliging major multinational companies (MNCs) to pursue or maintain higher ideals before granting them certification (Cole & Brown, 2014). Simply put, the increasing incorporation of the Fair Trade stamp without completely implemented Fair Trade ideals undermines the general objectives of Fair Trade principles and

William Faulkner's Barn Burning Essay Example | Topics and Well Written Essays - 1250 words

William Faulkner's Barn Burning - Essay Example Faulkner has used the plot, and the interactions between the characters, to explain the concept of mental and emotional slavery in man. However, what strikes most in Faulkner’s story is the use of symbolism. Through different symbols in the story, the author has described the internal conflict that a human being experiences before he succeeds in getting freedom. Hence, it is a story of spirit of freedom in human beings. In the short story, Faulkner has also explained how slavery is not just situational in nature, but also psychological. The author has made an excellent use of symbolism to explain the nature of freedom in people’s lives. According to Faulkner, the strongest obstacles in achieving freedom in life is not the external circumstances, but the internal demons of emotional and psychological attachment to destructive and negative people in life, and hence, the only way for human beings to get freedom in life is to win over the internal demons, because they are m ore dangerous than the external circumstances of slavery. Symbolism The story ‘Barn Burning’ is an excellent work by William Faulkner, where he has used symbolism to explain the purpose of his story. Symbolism is a method of describing the essence of a story ‘indirectly’ through objects, events and actions of the characters in the story. In case of the short story ‘Barn Burning’, the author William Faulkner has used interesting symbols to describe the conflict, spirit of freedom, rebellion, and courage in human beings. Right from the first paragraph of the story, the readers sense the use of symbols in the story. The author has used symbolism not only through objects but also through the actions of the characters. The symbols that he has used are blood, Sartoris’s actions and peculiar behavior patterns of characters in the story. Blood Right from the beginning of the story, the author grips the attention of the reader by introducing him to the complex idea of smell and its associations in life. Human beings have a tendency of developing mental associations with things related to sensory objects. For example, if a person listens to a song that was his favorite in the childhood, then the memories of childhood floods to his mind and he relives the good and bad experiences associated with that song. Faulkner has used the ‘sense of smell’ as a symbol of conflict in the mind of Sartoris Snopes, a ten year old protagonist of the story. The story begins with the description of the court proceedings against Sartoris’s father, who is accused of burning the barn of his owner. The proceedings take place in a store where the tins of cheese are kept. The boy is shown going through an internal conflict through the sensation of smells. Sarty (Sartoris) is found torn between the smell of cheese and the smell of ‘blood’. Sarty is sure that he smelt cheese even though he is unable to read the letters on the tin cans. The smell is pleasant and he likes it. However, he is unable to enjoy the smell of cheese as it is polluted with the smell of ‘blood’. Here, the author has used ‘blood’ as symbol of ‘loyalty and duty towards the family’. The smell of blood is not ‘real’ but is a psychological symbol of ‘family’. Interestingly, the smell of blood that Sarty senses is also joined by the sense of fear. It reminds Sarty of the despair and grief that he has experienced. Sadly, the smell of cheese that he senses is momentary and comes intermittently. However, the smell of blood is permanent and consistent in his mind. The words ‘fierce pull of blood’ shows that Sarty is somehow being forced to be loyal to his family, and particularly, towards his father. The word ‘

Intervention plan Essay Example | Topics and Well Written Essays - 1500 words

Intervention plan - Essay Example Apparently, her painful memories of such a traumatic experience were triggered when she and her workmates visited a friend’s farm in the country. While in the farm, she had flashes of her painful childhood memories which she thought she has forgotten over the years. However, the sights, smells, sounds, etc. of the farm only made the flashbacks more vivid. Sherry was only four years old when her grandfather began sexually molesting her in his barn. He did this to her until she was nine years old when she and her family had to move to another city due to her father’s employment. Sherry used to adore her grandfather because he brought her on trips around the country side and had ready treats for her every time she and her parents came to visit him and her grandmother. It is in the barn when he would sexually abuse her in the guise of pretend play. Sherry did not enjoy that kind of play at all and felt uncomfortable with her grandfather’s touch. Even if she was already toilet trained, she would sometimes soil her underwear in the hope that her grandfather will not rape her. Although he told her that it was their secret and she was not supposed to tell anyone, she tried to tell her mother when she was five years old, and in response, she was spanked, in the belief that she was lying. She never told anyone again. Bowlby’s Attachment Theory (1969) is one theory that explains the development of attachment of children to their significant others. It posits that a person’s real relationships in the earliest stages of life shape his or her survival functions as he or she grows and develops throughout the life span. To Sherry, her attachment relationships to both her grandfather and mother may have been shattered by her disappointment in them. Ringel (2012) contends that children like Sherry develop disorganized attachments alternating between ambivalent and avoidant behaviors as well as dissociative behaviors like
