Newton's Law Cooling - Lab Report Example ’s law of cooling the change in rate of the object temperature is directly proportional to the ambient temperature and the own temperature difference. Ambient temperature involves that temperature of the environment. The law makes some statement that concerns the instantaneous temperature rate of change. Translating the verbal description into to the differential equation gives a differential equation whose solution is a function which tracks the total temperature record with time. In order to understand the Newton’s law of cooling, an experiment was set to investigate. The room temperature was recorded using a similar thermometer that was used in the experiment. The thermometer was placed the boiling water up to when the reading of the thermometer was about one hundred degrees Celsius. The thermometer was quickly attached to the stand and started counting whenever the temperature reached eighty degrees Celsius. The temperature was read and recorded for the thermometer each and every thirty seconds for duration of five to six minutes. The procedure was repeated to obtain good data set and the average temperature reading recorded on the data sheet. The fan was set to about six to nine inches from the thermometer so that the thermometer bulb is inside the stream of air after the activation of the fan. The thermometer position was observed on the stand for the thermometer to be set on the stand at about the same position as in the previous experiments. The procedure was repeated. The fan was started and set to be low, the procedure was repeated with the fan on. The position of the fan was not changed between the experiments and the thermometer placed on the similar location as per the fans in the experiment. The prior procedure was repeated with the fan on a higher setting. The obtained data was recorded in table 1 and 2 under the result section of this report. According to the obtained results T(t) is the temperature at time t in minutes and T(0)a involves the

Native America and Hispanic Cultures in Michigan Research Paper

Native America and Hispanic Cultures in Michigan - Research Paper Example (US Bureau of Census 2008) I will address these two cultures separately in this paper but that both would be examined through the same parameters as demonstrated by the concept maps previously drafted. The parameter worked around three issues. These are education, family traditions and political background. I believe that these factors collectively characterize the wider cultural characteristics of the subject cultures. In regard to education, it varies through time and across cultures and so, it is necessary in establishing the cultural background of an ethnic group. Family traditions, meanwhile, reflect the way of life of the ethnic groups and, hence, demonstrate their culture. Finally, the political background was included in order to determine the minorities’ views on social issues in the context of their way of lives. These three variables characterize the cultural dimensions required in order for me to achieve my objectives. The methods employed for the research of sources used is a mix of first-hand interview, first-hand sources from government publications and research of second-hand sources from available literature such as books, journal and magazine. In regard to internet sources, the keywords used in the research include â€Å"Michigan demographics,† â€Å"Michigan Native Americans,† â€Å"Michigan education statistics,† and â€Å"Michigan voters profile.† The main search engine used was Google. I think the most important sources would be the government data from the US Bureau of Census as they represent the holistic status of the both the ethnic groups demography and cultural background. Because of this, it became easier to compare specific characteristics. The first-hand sources and interviews are also important because they allowed me to confirm and experience the major findings of the research. Because of this I was able to synthesize all the information that I was able to collect from all the relevant literature

Rising Fuel Costs and US Transport Industry Essay

Rising Fuel Costs and US Transport Industry - Essay Example Consequently, comfort is often sacrificed in an attempt to cut back on the fuel budget. Often, Americans have had to make do with fewer cars, or shift to fuel efficient ones. In addition, car pooling has become a common practice among friends and families while air travel is not only restricted, but also limited to either official travels, or longer journeys that would otherwise be uneconomical with the use of a car (Coyle et al, 2006). By and large, the use of public modes of transport has increased. In fact, ridership by public transport in the United States rose by 15 percent in 2007. For those in the taxi business, these have especially been hardest hit , and this has forced some of the operators to increase fares, only to have their customers walk away from them (ACTE, 2008). The airlines too, have not bee spared either, with a coupe of them such as Delta and American airlines recording massive annual losses in the range of $ 1 billion (KLEIN, 2008). With such a gloomy picture having been slapped on the American transport industry, is there any respite for the Americans in the near future For the last six years, the price of gasoline, crude oil and natural gas has significantly risen. In 2000, a barrel of crude oil ranged from $ 25 and $ 30 per barrel. This was later to rise to a high of $ 75 per barrel six years later. Due to this, such petroleum products as jet fuel, gasoline and diesel fuel, and which are primarily dependent upon by the transportation industry in the United States, have risen sharply. In addition, the price of a gallon of unleaded gasoline almost doubled to $ 2.36 in 2006, up from $ 1.46 in 2000. The rate at which both India and China are developing, has led to a sharp demand for oil, and this has had a massive impact on the petroleum-based products such as gasoline (Hiare & Machemehl, 2007). The reliance of the transport industry on fuel is in no doubt, and its usage keeps on increasing by the day. In 1973, the consumption of petroleum was pegged at 9.05mb/day, and this was later to rise to 13.9mb/day by the year 2005. In addition, there was a strong growth in petroleum consumption to 28.2 percent in 2005, up from 24.6 percent in 1973. Furthermore, the annual average vehicle per capita mileage has also immensely improved from 5,440 miles in 1970, to 10, 087 miles in 2005 (ACTE 2008). Automobiles For the automobile makers, they too have not been spared by the rise in fuel cost, as customers are no longer shopping for cars. Both Ford and General Motors have witnessed a slump in sales in recent years, leading to a recording of major losses. As a result, the auto makers have had to institute changes (VOA news, 2008). According to Rich Wagoner, the chairman of General Motors, the company has no choice but to close down some of its factories, following in the footsteps of Ford motors, who proceeded by closing shop on the manufacturing factories for non-fuel efficient vehicles. The General Motors boss views this as a proactive move, in a bid to ensure the survival and success of the company. This will mean that thousands of jobs will have to be cut down. There is also a shifting trend in the auto industry towards the manufacturing of

social Science Fiction In Asimovs Work :: essays research papers fc

PART I"Social science fiction?"Science fiction is a term familiar to many people. This is especially true due to the tremendous influence of television. But the term "social science fiction," although not heard too often, is a term is descriptive of most of today's science fiction literature."But what does it mean?"Social science fiction is the term given to literature "which is concerned with the impact of scientific advance upon human beings."(1) It is to be set apart from the adventure or "gadget" science fiction which is characterized by simplistic plots and flat characters. Social science fiction is concerned with the problems presented to humanity by technology and science.This theme can be seen readily throughout many of Isaac Asimov's science fiction works. But, Mr. Asimov was not too concerned with the problems of atomic power or overpopulation when he was three years old.Asimov was born in Russia in the year 1920. He and his parents emigrated to the United States when Isaac was three years old. Upon arriving, young Asimov wasted little time in beginning his writing career. He had taught himself to read and by the age of seven, he had his own library card.(2) But, of the two books he was allowed to take out, only one of them could be fiction. Thus, Isaac took a liking to many science and history books, and his amazingly retentive memory allowed him to recall many of the things he read.Because of his excellent reading habits and his superb memory, Asimov was considered brilliant when he entered school. A grade of 95 from a person capable of 100 was considered a poor grade by Isaac's father. Although he was an excellent student, Asimov was frequently bored by school. In order to escape boredom, he would create stories in class for himself and others. Although he did this verbally at first, he began writing down his stories at the age of eleven. Yet these in-class activities did not distract him from his schoolwork. He graduated the Boys' High School in Brooklyn when he was fifteen. From there, he went on to receive a B.S. from Colombia University in 1939, a Masters in 1941, and then a Ph.D. in 1948.(3) Asimov says he would have continued his studies had it not been for World War II.Asimov's first exposure to science fiction occurred one day while he was working in his father's candy store.

Early Civilizations

Early Civilizations HUMA215-1205A-32 Topics in Cultural Studies Unit 1 Discussion Board Shannon Sullivan There were many different forces that have contributed to the cultural makeup of early civilization. The beginning of human culture predates back to thousands of years which can be seen through evidence that has been discovered. This evidence that was left behind by the earliest of humans is found by cave paintings that helped to understand how these prehistoric individuals lived and survived in their everyday life.One aspect that contributed to the cultural makeup is from geographical areas from where these early humans lived. The geographical region determined what their main focus was when it came to agriculture, hunting, trade and religion. The availability of these natural resources would affect the kinds of houses they lived in, the types of weapons and tools they used, the food they ate and the type of containers they used to store food and supplies (Trigger, 2003). A numbe r of social issues occurred because of this cultural makeup. These issues were the cause of war and conflicts between many of these early humans.One of the factors that caused social problems was a result of different spiritual and religious beliefs. Others factors were political, economic and the development of one’s social class. Since early civilization started, humans lived successfully in small hunting and gathering tribes. This was the dominant way of life until agriculture began to gradually replace hunting and gathering of necessities such as food, clothing and homes which was some of the main cultural influences on early civilizations (All World History for Us, n. d. ). Revisionist history can be bad.The problem with revisionist history is that it usually is written by someone who has a curriculum that they want to publicize. Most of this comes from inaccurate information from an unbiased viewpoint. Their minds tend to be made up prior to looking at the facts. This r esults in choosing facts that support their viewpoint and ignoring facts that disprove their predetermined ideas. Another problem with revisionist history is that it tends to judge people, cultures and experiences in the past by the values, ethics and morals of today's society.People in the past lived with the knowledge, superstitions, values and ethics of their day and should be studied to find the correct information. The only good thing about revisionist history is when the correct information has been given. All World History for Us. (n. d. ). Farming and the Emergence of Complex Societies.

The Effects Of Optimal Arousal And Performance - 1686 Words

Introduction The effects of optimal arousal and performance has been studied extensively in psychology. Throughout sports psychology it is known that there is an optimal arousal level at which athletes perform their best. In previous studies surrounding the relationship between emotional states and performance, have been examined using the individual zone of optimal functioning (IZOF). IZOF is a sport-specific framework that describes the relationship between emotional experiences and success on the basis of individual patterns (Ruiz, Raglin, Hanin, 2015). In a review done by Ruiz et al. (2015), it was found over 183 IZOF based studies making it one of the most popular models for an analyzing subjective experience and athletic performance. From past research the IZOF model has found that anxiety heavily influences performance of athletes and each athlete has an individually optimal level of anxiety, which with probability will lead to a successful performance (Hanin. 1978, 1986, 1989). Even though IZOF is one of most widely used models when examining arousal and performance, research using the model has its limitations. As a model, it focuses on individual patterns, therefore most research with the model has been used on individual athletes and not team sports. By applying the IZOF model to a team sport, there may be differences in the individual zones of functioning between those who take part in team versus individual sports. It could be that people in team sports onShow MoreRelatedPsychological Factor That Affect Sports Performance997 Words   |  4 PagesArousal is a psychological factor that can affect sports performance and is defined as the level of activation or readiness that an individual will experience when faced with a task (Malpeli 2010, pg. 369). Effective performance requires an athlete to achieve optimal arousal which can be recognised in certain arousal theories (Malpeli 2010, pg. 369). The level of arousal that is considered to be optimal varies among every individual (Abernethy 2013, pg. 304).

How Stress Affects The Body Health - 1838 Words

Ever wonder why people get stressed out either if it’s School, Marriage, work, and family? Or some good stress for example is a job promotion, buying a new house, and getting married. Stress can also affect the body health for example it can lead to cancer and cardiovascular disorders. All the stress the person can’t let go will hold on to the person in some form of guilt or regret and they will think about it over and over again and make scenarios in their head. When people are mostly stressed they usually drink alcohol or smoke tobacco to release stress and forget things for a while and enjoy it. That’s when people start getting addicted to alcohol, drugs, and tobacco. There is treatment for that for example to have a strong personal motivation and stop what they’re doing and try new things. One big stress is called PTSD which is called posttraumatic Stress Disorder, it means it’s an anxiety and traumatic experience, an example would be if a per son went to war, and after they came back from the war they can get flash backs and remember the event what happened and can’t stop thinking about it, another example would be a near-death experience where probably someone got in a car accident and almost died and survived the accident and they get flashbacks and have regret of what they should have done.
