The Physics Behind Parking :: physics science cars vehicles

Background: After a long day of cruising through town with your buddy, the two of you have grown quite an appetite. You spot a McDonalds at the top of a very steep hill. Unfornately a local biker gang must of had the same idea. Encredibly, the only available parking spot is on the street, uphill of nearly 15 Harleys. There are no other restaurants for 100 miles in all directions. Famished, your friend skillfully manuvers his car to the side of the road. The breaks shudder as the car comes to a stop on the hill. He holds the brake, puts it into first, and shuts off the car. Problem: Biker's don't take kindly to people messing with their bikes. Your friend is about to let off of the brake. Being the physics major you are, you have to decide whether it's safe to park or safer to go hungry. Your friends car is pretty old, and the e-brake hasn't worked for years. The car will be held in place solely by the moter. There are two mean looking bikers smoking outside entrance. They are watching you so there probably wouldn't be time to make a run for it. Known What You Know: Your buddy's car is classic, and I'm sure he would want to make more than an educated guess. I've done a little investigating to help you out a bit. I took a torque wrench to the motor, and resists it resists aproximately 46 ft*lbs of torque at the crankshaft. After the compression bleeds down this number is reduced to 38 ft*lbs. The cars rear differential has a 3.73 to 1 gear ratio and a manual transmission with a 3.35 to 1 ratio in first gear. The tires are 28 inches in diameter and the gross weight of the car is approximately 2100 lbs. The hill is often travelled by truckers, and on the way up you noticed a sign that said the hill was at a 26 degree angle with the horizontal. Summary: When the car is at rest this means it is in a system of static equilibrium. Gravity is pushing forward on the car, and the tires are pushing back on the car via the reaction force of friction in the motor. The steeper the hill, the greater the force of gravity acting on the car, the greater the reaction force in the motor must have. As stated before, the maximum torque that can be applied to the motor before it rotates is 38 ft*lbs.

Prevention Plan for Divorce Before Marriage

Phuong Ho Prof. Janice Falbert CDFS 321 Section 9 Personal Relationships Wellness Philosophy Paper (PRW) Fall 2012 Marriage is one of the most essential factors of human life. It creates the basis for everyone to pursue a better, healthier, and happier life. However, it is the fact that there are more and more couples marrying and then ending up with divorce, and this rate is increasing faster year by year. Actually, all the divorce cases are originated from some of the forms of emotional illness that gradually appear in each partner during the time of their relationship.It is good to cure these forms of emotional illness to solve the martial problems of the specific patients. However; it is absolutely the best when the original points are studied and determined before they become the serious and fatal clues to damage marriage. What I am talking about here is the prevention efforts to be applied to the time period before couples marry, not after. I also present my Prevention Plan con taining the ideas, of preventing any chances that can cause divorce, for pre-marital couples.This is the ultimate result of the combination of my total knowledge about marriage and the practical philosophy of Primary Prevention material. It is true that relationship before marriage plays an important role in coupled life ahead; it also builds the foundation for the good, healthy, and happy marriage. However, it is completely wrong saying that dating works effectively to screen out future divorces, particularly those that occur early in marriage.Actually, dating does not have anything to do with the separation of married couples. The point here is that dating and marriage are different. Of course dating is important to lead to marriage. However, dating is a step to get two people closer and to see if they are for each other, and marriage is a commitment with full of incidents and probabilities. Loving someone, committing to him/her, and living together for the rest of your life are t otally different. This illustrates well for the divorces happening early in marriage.Many troublesome things happen when marriage life starts out. Things change dramatically, and the couples have to work through themselves or asking for professional help or divorces is the consequence. Another reason to say that dating is nothing to do with future divorces is that dating not working out leads to break-up right after that. People do not wait until they get into marriage, and then regret for what happen and say goodbye to each other. It does not work this way.Really, problems can appear during the dating; couples tend to learn how to overcome it (just like married ones); however, if they cannot find the same solution for this problem, break-up is easy to be brought up right away. Separation in dating is a lot simpler and easier than marriage. No such couples resist each other’s problems until they get married. As what I said previously, my Prevention Plan, which I will introduc e to you, is built upon my martial knowledge and the information from Primary Prevention material. So what is Primary Prevention?It is actually a distinct level from the three-tier model, which is pretty much similar to the main Prevention model, containing Primary Prevention, Secondary Prevention, and Tertiary Prevention. Secondary Prevention (treatment activities) is about trying to decrease the length of time an individual or family experiences an emotionally distressful situation; Tertiary Prevention (rehabilitation activities) is about preventing the recurrence of a debilitating problem and to restore as high as possible the level of individual and family reorganization.Like the other two, Primary Prevention, considered as a hybrid form originated from Prevention, has its own characteristics and techniques, which are about aiming to reduce the incidence of new cases of mental disorder in the population by fighting against harmful forces which operate in the community and by str engthening the capacity of people to resist stress. So, unlike the purpose of Secondary Prevention shortening the time the patients resist and purpose of Tertiary Prevention avoiding the repetition of the illness, the Primary Prevention is more straightened method of anti-emotional-distress.It focuses directly on the fight against the mental illness created during the process by helping patients develop the abilities to avoid stress. Primary Prevention focuses mainly on groups of patients but for the specific problems that those groups obtain. To get a wider and deeper view of these concepts, let get back to the original Prevention. The fact is that the perception of Prevention is not new at all. The ideas that mental distress might be prevented and eliminated happened a long time ago, back to the ancient time.However, the fully attainable concept of Prevention as a Public Health treatment was recently developed when the number of serious mentally ill patients as well as divorces go es higher and faster. Prevention provides strategies that not only help all the patients take part in avoid illness and promoting health, but also enlighten the misunderstanding and wrong claims and opinions about emotional distress. Really, there were any people bringing on the ideas saying that major illness is surely in large part genetically determined and is absolutely not preventable, at most modifiable.Prevention proves that these ideas are wrong and that mental problems are not such diseases that can be hinted to any microorganism or DNA thread. They are actually troubles derived from the very normal routine life of each individual. Sometimes they can be cause from the factors of that patient’s life like family, friends, colleagues†¦; sometimes they are from the patient himself/herself. Therefore, because those problems are not genetic and instinctive, it is easy to result that they can be controlled, prevented, and eliminated. 4] So, how does Prevention do its j obs as a helpful treatment of promoting mental health and avoiding illness? The answer is in its technology given by four specific tools as Education, Community Organization, Competency Promotion, and Natural Caregiving. Each of them has different perspective, way of approaching, and practical application but they all have the same purpose of preventing mentally illness and promoting health. [3] My Plan of prevention of Divorce is a combination of martial and relationship tips, academic and proved material, and practically social information.The points are simple rules and tips to some people in their lives, but these people are failed to recognize or even ignore and underestimate them. This leads to number of serious consequences to their marriage lives, even divorces. As I mentioned, all my attention will be the Prevention applied to the time period before couples married. Firstly, the optimal step for the all couples before they commit to each other in order to have a good and st able marriage is to question themselves and each other â€Å"Am I sure? Are you sure? [6] That means a premarital couple have to make sure the other is the only one and their ultimate finish of love. Both of them have to make it clear that the other one think the same and is literally willing to commit to this life ahead. [5] There are some couples rushing to marriage by their contemporary passion and feeling without thinking reasonably. Certainly, this kind of marriage later will obtain many obstacles and problems and suffer from the multiple consequences including divorce if they do not ask for any help. Marriage is an important thing ever happening to a person.Make sure that is the right one and be ready to spend the rest time of your life with him/her. [1] The second point of the Prevention Plan is â€Å"Professional help is not supplementary, at all. † Some couples think they are fine with everything; all they need to do is go ahead and be ready for a wedding without th inking twice about this as a big incident that will change their lives forever. Premarital counseling is extremely important that helps couples have a clearer and more complete view of what is going happen and how things change dramatically after they become husbands and wives.Besides, this is also a chance for the couples to make up their mind again and see if the other one is really the one. This may create disappointments for some couples when they think they already know everything about their relationship (but they do not). However, this is one of the most effective ways to prevent the probability of divorces happen right before the marriage happens. [2] Another thing that affects most to the stability of marriage life of any couple is â€Å"Defining expectations can help build a good plan. † Any victorious battle has its own strategy.What are the expectations? They are intentions, standards, rules that are summed up by both sides of couple and will be applied for their future family. The same with this situation, a happy future house is not only built with love, but also with wisdom and knowledge. The expectations can be only found, treasured, and carried by communication, and the best way to communicate is, of course, talking. [6] Beside building, reinforcing, and enriching the love, respect, understanding to each other, the couples should take time having some serious talking, discussing about their future family.Many things this talking can come with are such as finance, children, sex, housework, religion, jobs†¦ Having a clearer and practical view of these factors can help couples avoid many unexpected issues popping up in their future life together. It will be a lot easier and simpler to avoid, deal with and fix these problems when the insiders already know the concepts of original issues. [2] Many people think it is wasting of time and unnecessary to spend their time for their future marriages while they have not even get married yet.Ac tually, this period of time is the bridge between the dating and marriage. Maybe dating does not work effectively to screen out future divorces, particularly those that occur early in marriage; however, preventing is much better than fixing. This period of time is the most magnificent transition step for couple to reinforce their points of view, concepts, and knowledge about the marital lives waiting for them ahead. Therefore, I can surely say that my Prevention Plan will work effectively in any society, including a nation with a high rate of divorces like U.S. As you can see above, this plan with three general tips is simple and trivial point in premarital relationship; however, missing, ignoring or even misusing them can lead to serious problems. Not only the citizens are educated about marriage promoting and divorce preventing, but also the influence of mental health service in U. S. will get more appreciations, attentions, and profits from the public. These profits can help impr ove the U. S’s medical health development in many ways also.The open behaviors that I encourage couples to do are completely suitably helpful for Americans especially young people to develop themselves a confidence in dealing with different situations that life brings to them. Number of stably happy families maintains and improves; divorce decreases; society is higher in standards; the country is stronger. The best way to get the Prevention Plan maximized its power is to publicize and popularize them as a guide for premarital, engaged, or long-termed couples.The therapists, professionals, or mentalists of Marital Mental Healthcare need to know about and encourage the couples to apply it. The plan should be also introduced to people by media like Science newspapers, Family or Health magazines, the online articles†¦ In order to get more results, the government also should legalize the law that each premarital couple have to take mandatory Marriage and Family course in orde r to have better perspectives of what they are going to face in the near future and to give them a chance to rethink if what they are doing is right or wrong.This will raise a flow of opposing ideas from media and public about imposing and frustrating premarital couples. This Prevention working means the rate of marriage of U. S. will decrease in some way also due to the cut way of couples who realize they are not ready for marriage. The birth rate is also stable due to the couples already talked about children issues before marriage. There are absolutely less poor or foster-care children due to the number of broken families reduce. The children’s future life quality is more clearly defined in a positive way. [1]Divorce rate decrease can lead to many social advantages and benefits to both people and government. My plan simply gives a little help to the couples that will be the future husbands or wives. Hopefully with its help, our nation will develop in a stable tempo. Though my plan plays as a tool to prevent Divorce for couples before marriage, it is the most important when the couples themselves are willing to do what the plan says.

Religion-Effect of Dispossession on Aboriginals

Religion Discuss the connection between the dreaming and the land rights movement. Aboriginal spirituality is determined by the dreaming. The dreaming is a complex concept of fundamental importance to Aboriginal culture, embracing the creative era long past of the ancestral beings as well as the present and the future. The Dreaming's importance to the aboriginal people is emphasised through it providing for the obligations and responsibility of the aboriginal people, and furthermore accounting for their past, present, and future.The dispossession of land of the aboriginal people has led to various problems, including psychological and social issues experienced by communities and individuals, who in the past, have been forcibly removed from their land, their ‘home'. The Land Rights Movement is a movement targeted at recognising the issue of dispossession and progressing towards a. Thus Land Rights Movement, a movement based on the claims by the Aboriginal and Torres Strait Islan der peoples to repossession and compensation for white use of their lands and sacred sites, became the resolution.The motivation of this movement was ultimately base upon Aboriginal peoples reliance on a sense of spirituality connected to the land. As the movement strengthened, so too did the awareness of the effect of the dispossession, leading to an increase in the movement itself, and also enforcing the Aboriginal people’s sense of spirituality. Essentially, it becomes evident that the importance of the Dreaming was ultimately the reason for, and motivation behind the Land Rights movement. Thus it is needless to say that the Dreaming is fundamental to the Lands Rights Movement.Analyse the importance of the Dreaming for the land rights movement Land rights are of critical importance in relation to Aboriginal spirituality, because the Dreaming is inextricably connected with the land. Therefore the dispossession of Aboriginal native land is also the dispossession of Aborigina l spirituality. The link between the Dreaming, land and afterlife holds significance spiritual importance to the Aboriginal peoples as the land is the resting place for all aboriginal beings. Furthermore each Aboriginal community is connected with the land through their spiritual totems.Specific areas of Aboriginal communities’ have important spiritual meaning for those particular groups of aboriginal people-these are known as sacred sites. What’s caratagoried in ever aboriginal sacred site is the connection to the Dreaming and aboriginal mythology. There are special responsibilities attached to sacred sites such as important ceremonies like weddings and it could be a place of death for an aboriginal elder. The identity of an Aboriginal person is inextricably linked to the land and hence the land is like a mother for the people.

buy custom Achilles in Homer Iliad essay

buy custom Achilles in Homer Iliad essay Death is a natural phenomenon and something that virtually no man can escape. Death has been described to have several interpretations such as life after this world, permanent rest, judgment time and etc. However, there is no vivid information of what happens after death, since there are virtually no accounts of people who died and came back to life. We all seem to pay less attention to thinking about what happens with the person after death. Still, much thinking was focused on the kind of death the person suffered and the circumstances surrounding his death. From this indication, I would say that Achilles is a personality, who does not deserve my sympathy in the story, The Homer Iliad. As a person, there were several instances, Achilles proofed that death is not an entity to be feared as it was inevitable and bound to happen to everyone. Achilles than was focused on this principle to kill as many people as possible and infringe pain to families. Achilles used to kill so many people that Xanthus, the river god, had to cry for space, because the water had been filled with an abundance of the dead. But Achilles would fight on. Ironically, when Achilles was at the verge of being killed, he prayed to Zeus to save him. Indeed, that was a moment for Achilles to have a fair taste of what he had been putting all those people through. With saying that he who pulls a machete dies from a machete, Achilles did not deserve any sympathy for his evil deeds. Though Achilles escaped death at the hands of the roaring waters, he certainly managed to taste some pain when he lost any compensation for his effort. Buy custom Achilles in Homer Iliad essay

DNA Definition and Structure

DNA Definition and Structure DNA is the acronym for deoxyribonucleic acid, usually 2-deoxy-5-ribonucleic acid. DNA is a molecular code used within cells to form proteins. DNA is considered a genetic blueprint for an organism because every cell in the body that contains DNA has these instructions, which enable the organism to grow, repair itself, and reproduce. DNA Structure A single DNA molecule is shaped as a double helix made up of two strands of nucleotides that are bonded together. Each nucleotide consists of a nitrogen base, a sugar (ribose), and a phosphate group. The same 4 nitrogen bases are used as the genetic code for every strand of DNA, no matter which organism it comes from. The bases and their symbols are  adenine (A), thymine (T), guanine (G), and cytosine (C). The bases on each strand of DNA are complementary to each other. Adenine always binds to thymine; guanine always binds to cytosine. These bases meet each other at the core of the DNA helix. The backbone of each strand is made of the deoxyribose and phosphate group of each nucleotide. The number 5 carbon of the ribose is covalently bonded to the phosphate group of the nucleotide. The phosphate group of one nucleotide binds to the number 3 carbon of the ribose of the next nucleotide. Hydrogen bonds stabilize the helix shape. The order of the nitrogenous bases has meaning, coding for amino acids that are joined together to make proteins. DNA is used as a template to make RNA through a process called transcription. The RNA uses molecular machinery called ribosomes, which use the code to make the amino acids and join them to make polypeptides and proteins. The process of making proteins from the RNA template is called translation. Discovery of DNA The  German biochemist Frederich Miescher first observed DNA in 1869, but he did not understand the function of the molecule. In 1953,  James Watson, Francis Crick, Maurice Wilkins, and Rosalind Franklin described the structure of DNA and proposed how the molecule could code for heredity. While  Watson, Crick, and Wilkins received the 1962 Nobel Prize in Physiology or Medicine for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material, Franklins contribution was neglected by the Nobel Prize committee. Importance of Knowing the Genetic Code In the modern era, its possible to sequence the entire genetic code for an organism. One consequence is that differences in DNA between healthy and sick individuals can help identify a genetic basis for some diseases. Genetic testing can help identify whether a person is at risk for these diseases, while gene therapy can correct certain problems in the genetic code. Comparing the genetic code of different species helps us understand the role of genes and allows us to trace the evolution and relationships between species

Globalization and it's effects on Hawaii Essay Example | Topics and Well Written Essays - 1500 words

Globalization and it's effects on Hawaii - Essay Example Being an island nation, Hawaii has always attracted tourists from among all regions of the world and it has remained their main source of revenue. Globalization has also facilitated transnational â€Å"capital flow, transportation, tourism† and other kinds of alliances amongst nations, which played a major role in boosting Hawaii’s economy (15). Thus, the phenomenon of globalization, on the one hand, has accelerated economic and technological developments in Hawaii, but, on the other hand, it has had devastating effects on its environment and ecological balance as well as reduces the employment opportunities of local population. The capitalist philosophy that the elimination of national boundaries and the â€Å"rational operation of the free market† nourish prosperity does reflect on the economic growth of the island nation (Sheppard 308). In early days, agriculture has been one of the main resources of Hawaii but â€Å"sugar transformed† the nation initially as an industry based economy (Firth 183). Subsequently, falling in tandem with the trends of globalization, the Hawaiian outlook further changed from an agricultural society to a service based community primarily gaining strength from the exponential growth in tourism and allied industries. This transition, characterized by the emergence of â€Å"new market forces† coupled with the â€Å"new technologies of transport† has further accelerated the economic development of Hawaii (179). Similarly, â€Å"economic globalization† can have several positive outcomes for countries, in terms of enhanced quality of life, as can be evidenced from the progress that Hawaii has made in various aspects (Globalization and Environmental Sustainability 259). In addition, the liberalized policies of immigration, and the ease with which it can be processed as a consequence of globalization,

Commnuincation skills Essay Example | Topics and Well Written Essays - 500 words

Commnuincation skills - Essay Example Passive listening is one directional communication whereby the receiver does not give feedback or make inquiries and probably may or may not comprehend the message of the sender. Passive listening is known to lead to mistakes that are costly, employees being unhappy and customer dissatisfaction. Some passive listening examples include listening to radio and television. Passive listening is one of the most common forms of listening in today’s world. While active listening is a two directional communication where both sides are contributing, as well as engaging in conversation. Furthermore, in order to become a better active listener, studying and training are necessary (Shwom and Snyder 36). Therefore, it is safe to utter that the listening skill that would enhance better communication would be active listening. In order to develop better active listening skills as well as bring success within a workplace of which every employer seeks, they are three main categories that need e mphasis, namely; accurate hearing, comprehension and interpretation, and lastly response. For example, distractions from the environment like noise from vehicles or ongoing construction sites can be considered a hindrance to accurate hearing while for comprehension and interpretation, which would include the language factor. An example to this would be if someone speaks in a different language, like say Spanish it is impossible to comprehend and interpret what has been said if the person does not know Spanish. In order to combat this, one needs to be multi-lingual, and this is where employers’ of multinational companies invest in, as well. In addition to being a more effective listener in comprehension and interpretation, the in cooperation of non-verbal communication and verification of personal understanding through queries and paraphrasing is necessary. Some examples of non-verbal communication would include voice of tone, facial expression, body language, as
