Effects of Electricity essays

Effects of Electricity essays In this lab, the effects of electricity were studied. This was done by observing the effect on a strip of metal foil when a charged rod was brought closer to it and by completing other similar experiments. These other experiments included examining the charge on common scotch tape and the various ways to give a rod charges. In the first experiment, a piece of tape was peeled off of the table and held close to some bits of tape, which it attracted. This showed that simply by removing the tape from the table, the tape became charged enough to attract the paper. Next, two pieces of tape were stuck to the table and when they were held together they repelled. The repulsion got stronger the closer together the pieces were held. Then, a piece of tape was hung off the edge of the table. A second was stuck on the table and a third was stuck on top of it. They were pulled from the table together and the peeled apart. When the bottom piece was brought close to the hanging tape, it repelled it. This shows that two pieces of tape, peeled from the same table, will share like charges, and thus repel each other. Next a series of experiments were completed using an ebonite rod, a glass rod, wool, silk, and an electroscope. In the first experiment, the ebonite rod was charged by rubbing it on wool and brought close to the hanging tape, which it repelled. This shows that the charge from the wool would easily transfer to the ebonite rod, and then share the same charge as the table and the tape. Next, the glass rod was charged with the silk and when brought close to the hanging tape it attracted it but when it was brought close to the straw in the electroscope, it repelled it, which shows that the tape shared the same charge, but the straw held an opposite charge. Then, the electroscope was neutralized with a finger and the charged ebonite rod was brought near the plate and the opposite side of the plate was touched with the finger...

1970 Palestinian Hijackings of Three Jets to Jordan

1970 Palestinian Hijackings of Three Jets to Jordan On Sept. 6, 1970, terrorists belonging to the Popular Front for the Liberation of Palestine (PFLP) almost simultaneously hijacked three jetliners shortly after they took off from European airports on routes toward the United States. When hijackers on one plane were foiled, hijackers seized  a fourth jet, diverted it to Cairo, and blew it up. The two other hijacked planes were ordered to a desert airstrip in Jordan known as Dawson Field. Three days later, PFLP hijackers seized another jet and diverted it to the desert strip, which the hijackers called Revolution Field. Most of the 421 passengers and crew on board the three planes in Jordan were freed on Sept. 11, but hijackers held on to 56 hostages, most of them Jewish and American men, and blew up the three jets on Sept. 12. The hijackingspart of 29 hijackings attempted or carried out by Palestinian factions between 1968 and 1977triggered the Jordanian civil war, also known as Black September, as the Palestine Liberation Organization (PLO) and the PFLP attempted to seize control of Jordan from King Hussein. Husseins toppling failed, however, and the hostage crisis was resolved on Sept. 30 when the PFLP released the last six hostages it held in exchange for the release of several Palestinian and Arab prisoners held in European and Israeli jails. The Hijackings: The Five Planes PFLP hijackers seized a total of five planes during their September 1970 operation. The planes were: Sept. 6: El Al Flight 219 from Amsterdam to New York, a Boeing 707 carrying 142 passengers and crew. It was Hijacked by Patrick Argà ¼ello, a Nicaraguan-American doctor, and Leila Khaled, a Palestinian. An Israeli air marshal and passengers on the plane subdued the hijackers, killing Argà ¼ello. The plane landed safely in London. British authorities released Khaled on Sept. 30 as part of a deal for the release of hostages held in Jordan.Sept. 6: Trans World Airlines (TWA) Flight 741, en route from Frankfurt to New York, a Boeing 707 carrying 149 passengers and crew. Hijackers renamed the plane Gaza One and ordered it to the Jordanian airstrip. It was blown up on Sept. 12.Sept. 6: Swissair Flight 100 from Zurich to New York, a DC-8 with 155 passengers and crew. It was over France when hijackers seized it, renamed it Haifa One, and ordered it to Dawson Field in Jordan. It was blown up on Sept. 12.Sept. 6: Pan American Flight 93, a 747 taking off from Amsterdam and carrying 173 passen gers and crew, was ordered to fly to Beirut, even though the international airport there didnt have a runway for 747s. One more PFLP member, an explosives expert, boarded the plane in Beirut. The hijackers then ordered it flown to Cairo, where it landed at 4:23 a.m. and was blown up shortly afterward.The hijackers told us the plane would be blown up, but they said it so politely and with such smiles that we couldnt take this too seriously, Cornelius Van Aalst, the flights service supervisor, told reporters in Cairo, after the ordeal. The hijackers were very friendly, according to Van Aalst, showing exemplary manners and helping to carry an injured woman in a blanket from the plane. Sept. 9: BOAC Flight 775 from Bombay to London, a VC-10, was seized while flying over Lebanon. (The British Overseas Airways Corporation is the forerunner to British Airways.) PFLP hijackers said they had seized the plane as a ransom for the release of Leila Khaled, the foiled hijacker aboard the El Al plane. The BOAC plane carried 117 passengers and crew. It was allowed to land in Beirut, where it refueled, then flew to Dawson Field in Jordan to join the two other hijacked jets there. Why the Hijackings PFLP leader George Habash had planned the hijackings with Wadi Haddad, his lieutenant, in July 1970, when Jordan and Egypt agreed to a cease-fire with Israel that ended the War of Attrition that had stretched back to 1967. Habash, whose militants had been taking part in raids on Israel from the Sinai, Jordan, and Lebanon, was opposed to the settlement. If a settlement is made with Israel, Habash vowed, we will turn the Middle East into a hell. He was true to his word. Habash was in North Korea (on his way home from Beijing), on a shopping trip for weapons, when the hijackings took place. That created confusion over what the hijackers were demanding, as they had no clear spokesman. At one point a hijacker on board the Pan Am flight said the PFLP wanted the release of Sirhan Sirhan, the Palestinian convicted assassin of Senator Robert F. Kennedy in 1968, and serving a life sentence at the California State Prison, Corcoran. The PFLP then submitted a formal list of demands that called for the release of Palestinian and Arab prisoners in European and Israeli jails. There were about 3,000 Palestinian and other Arab individuals in Israeli jails at the time. Over three weeks, hostages were released in tricklesand the hijackers demands were met. On Sept. 30, Britain, Switzerland and West Germany agree to release seven Arab guerillas, including Leila Khaled, the El Al Flight 219 hijacker. Israel also released two Algerians and 10 Libyans. The Jordanian Civil War PLO leader Yasser Arafat seized on the hijackings to go on the offensive in Jordanagainst King Hussein, who nearly abdicated his throne. A Syrian military column was on its way toward Amman, the Jordanian capital, in support of the Palestinian assault. But with the backing of the United States Sixth Fleet in the Mediterranean and even the Israeli military, which was ready to intervene on the kings behalf, Hussein mobilized his forces and turned them against Palestinians in a bloody three-week war. Hussein triumphed, severely weakening the hijackers stance. A turning point in the battleand the hostage crisiswas the Jordanian militarys rescue of 16 British, Swiss and German hostages held captive near Amman.

Energy, Sustainability and Renewability Assignment

Energy, Sustainability and Renewability - Assignment Example Various issues will be discussed in this assignment related to energy and its other variables. KEY TERMINOLIGIES For better understanding of this report some key terminologies have to be discussed in detail. These terms are the essence of this paper and cannot be comprehended without excessive research from different books and journals related to physics. Energy Although energy has been described in the introductory paragraph, a further analysis will be produced here. As described before that the ability of a system to do work on another system is known as energy. Coming towards the sub-division or the types of energy present in the language of physics. Energy can be divided into mechanical, solar, thermal, chemical, electrical, electromagnetic and nuclear energy. Mechanical energy is further broken down into two very important categories, potential and kinetic energy. Potential energy is the form of energy stored in a body for e.g. a fully stretched elastic band and kinetic energy i s the one when a body is motion for e.g. the same elastic band when being released. Sustainable Energy The fact that energy is utilized by burning or disfiguring other natural resources brings about the change in thinking of man, can we provide energy otherwise? The answer to this lies in the definition of sustainable energy. It is the provision of energy that meets the need without compromising the ability to generate energy in the future (Smith, 1998). Several factors go into making energy sustainable. The first is whether or not the current use of the energy is something which could potentially persist into the future, which leads many forms of renewable energy to qualify as sustainable. Therefore renewable and sustainable can be termed as in-lieu terminologies. Some of the renewable energy sources are hydroelectricity, solar energy, wind energy, wave power, geothermal energy, bio-energy, and tidal power. Examples Some of the examples of sustainable/renewable will be discussed in this report to better understand the various benefits and downsides of this form of energy. Hydroelectricity is the first term that will be discussed. It is one of the most used alternate energy being used in the modern world today. The flow of water in the river is used to turn turbines which in turn produce massive amount of electricity. Then comes wind energy which is the most blossoming alternate energy source in the commercial market is the ability to produce energy with the help of wind. Wind energy has had a huge impact in the energy industries. Wind farms have been set up in various windy cities of the world top produce large amount of electricity. The output power produced has been increasing by the day. The fact is clearly shown by the figure (Maggie, 2008) Issues with Renewable Energy Various questions have been raised with the alternate energy process. Although that the new renewable sources are cheap and effective, still many organizations and researches show that this form of energy production is more harm, since cost effectiveness is not the only issue at hand. Even before the low cost electricity is produced the problem which arises is that the setup of such plants which produce cheap energy, be it a dam or a wind city. Solar panels cost way more than burning fossil fuel and setting millions of panels for sustained energy providence is also a very costly factor. The problem is just not cost effective. Natural and environmental damages have huge costs

Palestine by Joe Saco Essay Example | Topics and Well Written Essays - 500 words

Palestine by Joe Saco - Essay Example On reading Joe Sacco’s graphic creation ‘Palestine’, I had my personal encounter of Palestinians under tumultuous state of oppression. It was as if I inevitably swam from the surface down to depths and depths of grievances which the Palestinian nation has every right to raise against the bureaucratic Israel. For one, Palestinians must be delivered from taking the ordeal of battling with armed Israeli soldiers who ruthlessly torture them to psychological, emotional, and physical deaths. Second of all, they deserve more than to grieve or wail at occupied territories which drove them out of their homes since the 1960s, making them live in inhumanely poor shelter conditions as refugees dwelling in camps without paved roads, proper roofing nor toilets as depicted in Sacco’s reports – a picture worse than an abandoned civilization. Moreover, I personally advocate support for Palestinians who express grievance for the absence of fair trial when their family members are put to jail at Israeli’s unjust discretion. The enemy’s brutish behaviour of inflicting extreme physical harm against the innocent in jail who barely know the grounds for their suffering must be highly condemned indeed.

Naturalism and Symbolism in the Poem Design by Robert Frost Essay

Naturalism and Symbolism in the Poem "Design" by Robert Frost The poem "Design" by Robert Frost is a sonnet written about man's relationship with nature. Frost deliberately uses the form of a sonnet, using the octave for a discussion and the sextet for questioning the fact that there is a force that controls our existence. There are natural characters and some degrees of irony also that give this poem a naturalistic feel. Frost uses the style of a sonnet in "Design" to present a philosophical problem - who controls our destiny. The octave is a single, smooth flowing sentence full of description. We are introduced to three things the narrator happened upon one day. There is a scene of contradictory pictures. The color of the white heal--all, the white spider, and the white moth all suggest purity and innocence. These are the, as the speaker describes them, "characters of death and blight." The octave has a lighter tone than the sextet. Even thought the tone is lighter there still seems to be a tension and seriousness that flows evenly to the sextet, which seems to bring chills to the reader's spine. The sextet is a series of questions that reveals a blend of emotions. The sextet brings about an unexpected change in tone. The poet is no longer observing, but questioning. The first question sounds like he is questioning something that doesn't fit in. The next question brings about a harsher image. The last question is the revelation into the speaker's torment. In the sextet, where the issues are raised, they should be solved in the following octet. They are not. Frost poses three unanswerable questions. The speaker seems reluctant to asks these questions and face them openl... ...ting there. It may be considered fate. The fate of the moth lay in the spider eating it. It was born to fly near that white flower and feed the spider. There is also a third reason that could be addressed. Naturally, a white moth would be attracted to a white flower as camouflage from predators. The white spider would use the flower as concealment from prey. There is a design at work but not a "design of darkness." It is simply an order of nature. It can be attributed to survival of the fittest. The final verse however calls to doubt not just evidence of natural darkness but the entire epistomogical basis of the poem. Is there someone or something controlling us or are we so small that is doesn't really matter in the grand scheme of things. "If design govern a thing so small" questions the result and method of the rest of the poem.

Death of a Salesman Willy Loman’s Mental Breakdwon Essay

In Death of a Salesman Willy Loman was a man made of false dreams. Willy Loman was a man who destroyed himself with his false hopes and dreams. Throughout his whole life he was trying to become a Salesman like his father and he thought he would die a rich and successful man. Willy Loman was a man who tried so hard to achieve the American dream but failed to do so due to the multiple circumstances throughout his life. Environment around Willy Loman has had a huge affect on him which is causing him to be instable. Willy is not only destroyed by his own ideals but destroyed by his own two children Biff and Happy and Howard firing him also broke him down even more. Willy Loman is destroying himself trying to achieve the American Dream and trying to become a salesman like his own father but is failing to do so. He wants to own his own business. Willy also wants to be â€Å"bigger† then Uncle Charlie and that is why he never takes a job under Uncle Charlie even after getting fired. He wishes to die the â€Å"Death of a Salesmman† where many people to mourn for him and remember him as a great salesman. Willy has spent his whole life trying to achieve all these dreams of his but he still hasn’t really achieved any of them which is causing him to have a mental breakdown. However Willy aims in life have been useless as he hasn’t really achieved anything. Willy Loman is constantly lying to himself and his family to escape from being a failure. He is constantly trying to achieve his dream of becoming a great salesman but is lost in reality and is running out of time. In the play Charlie said to Willy â€Å"When are you going to grow up. † Even though Charlie was made fun of by Willy he still is his only friend and cares for him and even offers him a job after Willy gets fired by Howard but Willy refuses to take the job because of his high standards and his dreams which he hasn’t be able to accomplish yet. Willy knows he hasn’t accomplished anything yet and that is why he is guilty and starts lying to himself and to his family and even goes on and has an affair with another woman. He has the affair with the other woman to give himself a â€Å"boost† or to go into another world because he feels he has been a failure at not achieving the â€Å"American Dream. † Having an affair also caused Willy to breakdown because Biff caught him cheating and Willy feels guilty about it. Willy put in his whole life for his sons, Biff and Happy and they turned their backs on him. Willy always loved Biff and thought he would be an amazing business man but after Biff saw Willy cheating it tore Biff apart. Biff failed math and went to Boston to get his dad to talk to his math teacher but at that time he caught his father cheating which made him not get along with his dad for the rest of his life. Willy knows deep down it his fault that Biff never became a successful business man. The fact that he feels guilty is also a huge factor in his mental breakdown. The psychoanalytic theory describes how the environment around a person has an effect on the person. In Willy’s case it his sons and his failiures in life which is causing him to be unstable. From the multiple causes of Willy’s mental breakdown the biggest thing that broke him down was when Biff at the end of Act II shows him the rubber tube he found and explains to him that he was never what Willy wanted him to be. After all that Willy realizes his sons actually do love him even though they aren’t successful businessman. When will realizes he is almost finished is when Biff says â€Å"Pop, I’m nothing! Im nothing Pop. Cant you understand that? There’s no spite in it anymore. Im just what I am, that’s all. † Biff also says â€Å"Will you let me go for Christ’s sake† Will you take that phony dream and burn it before something happens? After this situation Willy realizes he has not accomplished much in life and his life is almost finished but Biff does love him. Willy has been chasing the American dream for ever trying to follow his father but has never succeeded which has caused him to fail throughout his whole life because he never really did what he was good at which was using his hands. After Willy committed suicide biff tells us what Willy could have been which could have made him successful. Biff says â€Å"Charley, there’s more of him in that front stoop than in all the sales he ever made. † This shows that Willy was never a salesman but was good with his hands. The played concluded with Willy committing suicide so his sons could collect the insurance money and because he had realized he was a failure in life but still wanted his children to be happy and successful. The multiple complications lead to the destruction of an American Dream. Willy wanted a dream that seemed materialistic and unimportant which caused his own life and destruction of his kids. Willy trying to chase the American dream and trying to be better then Charley and trying to be like his dad caused him to be a failure and eventually take his own life. Him not being able to achieve his dreams throughout his life caused him to be a failure and destroying his kids as well.
