Measurement of Free

Measurement of Free-Fall Acceleration Essay Introduction Galileo Galilei (1564-1642), the man first accredited with the correct notion of free-fall with uniform acceleration, stated that if one were to remove entirely the resistance of the medium, all materials would descend with equal speed. Today, this statement holds true for all objects in free-fall near the Earths surface. The purpose of this experiment is to verify Galileos assertion that acceleration is constant. In addition, the magnitude of acceleration will be calculated. Theory By definition, acceleration is the rate of change of velocity with respect to time. Instantaneous acceleration is the derivative of velocity with respect to time. a(t) = dv / dt. Average acceleration is the change in velocity during a time interval, Dt, divided by the length of that interval, aave = Dv / Dt. In this experiment, average acceleration of gravity will be determined by measuring the change in position of a falling object at regularly timed intervals. With this, average velocities for these intervals will be calculated. A graph of the average velocities versus time should give a straight line whose slope is the acceleration of gravity (g). Apparatus To determine the acceleration of gravity the Behr apparatus will be used. The device consists of two vertical conducting wires, a thin strip of paper held  between them, and a metal-girdled weight designed to fall between the wires along the length of the paper strip. A spark timer transmits a high voltage electric pulse to the wires approximately 60 times a second. Every time a pulse is transmitted, two main sparks flow through the system. One spark passes from one wire to the metal girdle around the weight. The second spark causes a small burn in the paper, marking the location of the weight at that instant. Procedure Turn on the electromagnetic power supply and suspend the weight from the end of it. Confirm that the weight falls smoothly into the cup at the base of the apparatus when the electromagnet switch is turned off. Run this test run about three or four times before you continue. Next, draw a fresh strip of paper from the base of the device and clamp it in place. Turn on the electromagnet, and suspend the weight at the end of the magnet. Hold down the spark switch, and then immediately turn off the eleectromagnet power supply. The weight should fall down to the base of the apparatus, causing sparks to pass between the two wires and itself. Turn off the power to the spark timer and inspect the paper strip. A series of burns should be visible along the length of the paper. Remove the paper strip from the apparatus and immediately mark the spots with a pen or pencil to see them more clearly. Data and Results The following table shows the data calculated for the experiment. The spots found on the paper strip are shown as (n). The distance of the metal girdle along the strip is denoted by (x). Velocity is (v) and acceleration is (a). The estimated time (Dt) for this test was 60.2  ± 0.7s-1.

The average of uncertainties for the calculated accelerations is a better as choice of uncertainty because it provides a narrower field of uncertainty than does standard deviation. In conclusion, the calculated value of 9.47  ± .69 m/s2 for acceleration is acceptable.

English Immersion Programs: Who is Targeted? Essay -- Essays Papers

English Immersion Programs: Who is Targeted? The topic of immigrant students entering not only our country but our public school systems, is slowly becoming a bigger and bigger controversy within the United States. Students are coming in from all over the world and entering our English-speaking school system without a word of English in their vocabulary. When they are thrown into the melting pot of today’s pubic schools, their presence affects so many more people than one would think. My belief that English immersion should replace bilingual programs can be correlated with three main groups all taking opposing stances on my argument. The three primarily affected groups are the immigrant students themselves, today’s workforce, and the bilingual education teachers. These three groups, all things considered, all take different approaches to the abolishment of bilingualism. Students would most likely agree with English immersion so that they can adapt better and sooner, while teachers would most likely disagree because their entire curriculum and teaching style would be subject to drastic changes. While these two groups are extreme opposites, today’s workforce serves to go either way. The three groups: students, the workforce and bilingual education teachers, serve as representatives for the many sides of the controversial changing of bilingual education in today’s high schools. Students are without a doubt, the most affected group within the bilingual education controversy. They are the children who are entering a new environment at one of the most crucial time in their lives. They need to learn the academics to help them succeed in the future, but how can they learn anything if they don’t even speak English? Fo... ...English immersion programs. There are perhaps thousands of groups that are and will be affected by bilingual education now and in the future. However, three main groups are affected more directly than most. Their correlation with the bilingual education controversy makes their standpoint on English immersion very biased. Students, today’s workforce, and bilingual teachers take very different sides when the education debate is considered. These three groups represent different sides of the growing controversy over the replacement of bilingual education with English immersion education in the United States.

International Management and Ethics: Culture Dimensions

INTERCULTURAL MANAGEMENT & ETHICS ACTIV-1 ACTIVITY 1 – TOPIC 1: CULTURAL DIMENSIONS DIALOGUE 1 1) Which cultural differences cause the misunderstanding or confusion? Which cultural dimensions can help us understand the situation? On my understanding of the situation – bearing in mind that when in a multicultural dialogue, many meanings can be found or understood by just context without the use of words – I believe that the confusion has its origin by the cultural difference amongh both characters. The conversation lied on Mr. Bakr’shoulders although Mr.Amstrong tried to redirect it to the field that was occupying his mind but without success. Mr Bakr has the strongest part of the dialogue: having a flexible concept of time, paying more attention to social talks –business small talks in this specific case – , focusing to address the conversation to become more social and mentioning the religion makes Mr. Amstrong to have a conflict with his cu ltural dimensions. Mr Bakr coming from an arab culture through this dialogue shows to be polychronic, particularistic, control oriented and collectivist.The reality could be a little bit different from my own words here. We need also to bear in mind the context where this conversation is taking place, the circumstances and sometimes, even the mood of the interlocutors. Mr Amstrong really wants to skip the social talk to stick into business but should he knew that Mr Bakr’s culture gives more importance to social talk rambling would have accept it and take some more time on this to try to redirect the conversation to his key point afterwards. 2) How do you think that the people involved feel in regards to his / her partner?How would they interpret the other party’s answers? I think in this case Mr Amstrong may have felt a feeling of frustration as well as distressed since he can think that Mr Bakr has been rude to him for avoiding the topic he wanted to talk about it. M r Bakr may have not probably even noticed Mr Amstrong’s troubles otherwaise he could have done something change it during their conversation. However Mr Bakr could also feel upset for Mr Amstrong’s insistence on the distribution subject. So from a small thing could become a big misunderstanding and depending on the context this could be a very grave problem.Maite Molina Sabate MIBTM INTERCULTURAL MANAGEMENT & ETHICS ACTIV-1 3) What would be helpful to avoid misunderstandings? Why is Mr. Amstrong unsuccessful trying to get the conversation where he wanted? This may be due to that Amstrong’s and Bakr’s cultural dimensions were just opposite to each other’s and neither of them tried to understand each other’s different cultures and respect that it is necessary to adapt oneself to other’s at some stage and show respect. And this should have been done by both parts. In real life this is not happening as often as it should.Most situations a re resolved by one of the characters taking the lead and the other respecting the culture difference and filling the gap as better as possible showing respect. But before introducing ourselves in another culture context –either by a meeting, a business trip or any sort of communication with someone from abroad – we should need be more conscious about the possible cultural differences and learn a little bit about customs and facts from that other culture in order to understand better the person who we will communicate with and the communication we will be holding.DIALOGUE 2 1) Which cultural differences cause the misunderstanding or confusion? Which cultural dimensions can help us understand the situation? I don’t see any confusion or misunderstanding in this second dialogue but an understanding. However if a subliminal confusion or misunderstanding is flowing it might be for the situation itself. Carolina’s priority is her daughter’s illness and so taking her at the doctor’s appointment whilst Alice is thinking in setting up a time to hold a meeting.Fortunately this meeting can be reschuled so there’s not a big problem on this situation. Cultural dimensions that could bring this situation would be from Carolina: polycronic (her sense of times and priorities can be diverse from anglo’s Alice), particularistic (decisions can be made by subjective decisions like in this case), a little bit egalitarian (in this case there’s no hierarchical since the meeting will be moved for everybody due to Carolina’s personal reasons and this brings us to the individualist concept as well.For Alice could be as follows: Hierarchical, collectivist (she moves the meeting’s day to meet Carolina’schedule) and harmony oriented since she is willing to adapt her and the fellow colleagues to Carolina’s needs. 2) How do you think that the people involved feel in regards to his / her partner? How wou ld they interpret the other party’s answers? I believe that in this situation Alice may feel frustrated since she cannot help but moving the meeting to help Carolina’schedule. Very understandable and comprehensive by her side but leaving business hierarchy and control aside.If every employee would ask for a change that would be needed and finding a date for a single meeting could be a nightmare every time that the question would arise. So some organization should be on demand or company’s policy to try to organize this gap at Maite Molina Sabate MIBTM INTERCULTURAL MANAGEMENT & ETHICS ACTIV-1 the same time as supporting employees that need some sort of help with personal and professional lifes. Carolina can feel very relieved to have Alice’s acceptance and support for the situation and very valuable for the company since not just understand the situation but change the date so she can assist. ) What would be helpful to avoid misunderstandings? In this cas e a good communication and having an internal policy to follow that would organize this and support either the employees as well as managers. Good communication is important because Alice could knew about Carolina’s problem earlier and reschedule the meeting beforehand and not just the day before. Carolina should know that a company needs an organization a hierarchegy so if she needs some time off that should be regulated and everybody that should need to be informed beforehand.

Colgate Palmolive’s Strategies Essay

A distribution channel is defined as a set of intermediaries performing a variety of functions. These interdependent organizations are involved in the process of making a product or service available for use or consumption. Marketing channels for a product are considered one of the more important decisions made for a product. It is believed that these channels not only serve the markets that the products move thru, but they make the markets. Distribution channels determine the price thus the profit of any given product. The final stop for any product/service is the consumers, what channels the product move through has many options. One very important decision in the channel is the push verse pull marketing. A company’s push strategy uses a sales force and other promotions to pursued intermediates to carry, promote and sell the product to the consumer (Kotler & Keller, 2009). This strategy is most effective when market share or name recognition is low, when consumers have no brand loyalty and product benefits are well known. In contrast, pull strategies use advertising and promotions to provoke consumers to request the product from intermediaries. The strategy is successful when consumers make a choice prior to purchase and choose based on brand loyalty and name recognition. A company must first identify the types of intermediaries available to assist with distribution to the consumer. When Colgate-Palmolive developed the new Precision toothbrush, they had to determine the distribution channel for the product. Like its other products, the Precision toothbrush would be sub-contracted to Anchor Brush. Anchor Brush would produce the new toothbrush (which required three different types of equipment), warehouse- hold inventories, and handle transport- channel is responsible for ensuring quicker delivery. Precision’s positioning as a niche or mainstream product played a major part in the pricing and production schedules being determined. Each positioning had a different effect on pricing and adequate supply for the market. The product positioning also determined what markets and where the product would be sold. Since research had shown the new product would create a new market of consumers and Colgate-Palmolive was an established brand in the toothbrush category, a â€Å"pull strategy† would seem effective. CP could collaborate with Anchor Brush, and sell the niche Precision toothbrushes in food and drug stores. Selling a mainstream Precision toothbrush would send product to mass merchandisers and club stores. Prior to the introduction of Precision toothbrush, Colgate-Palmolive did not sell directly to dentist, a definite area of opportunity for the product, whether niche or mainstream. Colgate-Palmolive like most companies developed a product and determined what distribution channels would be used to get the final product to the end users/consumer. A production, warehousing, and transporting partner were used to move the product to the final stage of the process, retail stores for consumer purchase. Colgate-Palmolive could benefit from using a sales force that worked directly with dentist to distribute the Precision toothbrush. This partnership between the niche product –Precision and dentist would increase awareness and provide â€Å"expert† endorsement to the new product. Once the demand was increased- fueled by dentist promotion, Precision can be moved to a mainstream product with little adjustment in production and warehousing. Colgate-Palmolive’s uses a vertical marketing system strategy to move the Precision toothbrush to market. Colgate-Palmolive is the channel captain with name recognition and the product ideal that the producer, warehouse, and transporter collaborate with to produce the product.

Personal Impact of Substance Abuse Research Paper

Personal Impact of Substance Abuse - Research Paper Example You came light at night and that is what made your eldest son to bring you over here. You need to see the fact that your kids need you right now. They are also going through the same phase as you are but they are trying to cope with it. They have already lost their mother and they do not want to lose their father as well. If you will go on to take alcohol like this, you won’t only destroy your life but you will also be responsible for snatching away the future of your kids. Instead of being calm and patient with them, you shout at them and indulge in arguments with your loved ones (Wolfenden, 2010). Whenever you drive with alcohol in your body and mind, you are risking your life. You exhaust yourself, you make yourself numb through alcohol and thus you do not have the energy to talk to your kids. It is necessary that you communicate with them. In this way, not only you will feel better but your kids will also feel better. If you will keep on taking alcohol, you will be subjecting yourself to heart diseases (Wolfenden, 2010). Moreover, these habits also lead to high blood pressure which in turn leads to strokes, acute kidney failures and in many sever cases, cancer. When you said that you have tried to stop, but could not, it is because you cannot get rid of this problem in a day. You need medical supervision when you withdraw from this alcohol abuse. The symptoms are direr when you stop taking it after a period of over dose. You will suffer from headache, nausea; increase in the heart beat level, decrease in appetite, tremors, exhaustion and sometimes insomnia (Wolfenden, 2010). But you should not worry because this all is normal when you withdraw from alcohol. After a month or two you start to feel immensely better. You will also be given some medicines to curb the urge of drinking alcohol. These medicines will be temporary and will be stopped after a certain time period. You need to organize your life once again, and I understand that it is easier said
