One-Dimensional Kinematics Motion in a Straight Line

Before beginning a problem in kinematics, you must set up your coordinate system. In one-dimensional kinematics, this is simply an x-axis and the direction of the motion is usually the positive-x direction. Though displacement, velocity, and acceleration are all vector quantities, in the one-dimensional case they can all be treated as scalar quantities with positive or negative values to indicate their direction. The positive and negative values of these quantities are determined by the choice of how you align the coordinate system. Velocity in One-Dimensional Kinematics Velocity represents the rate of change of displacement over a given amount of time. The displacement in one-dimension is generally represented in regards to a starting point of x1 and x2. The time that the object in question is at each point is denoted as t1 and t2 (always assuming that t2 is later than t1, since time only proceeds one way). The change in a quantity from one point to another is generally indicated with the Greek letter delta, Δ, in the form of: Using these notations, it is possible to determine the average velocity (vav) in the following manner: vav (x2 - x1) / (t2 - t1) Δx / Δt If you apply a limit as Δt approaches 0, you obtain an instantaneous velocity at a specific point in the path. Such a limit in calculus is the derivative of x with respect to t, or dx/dt. Acceleration  in One-Dimensional Kinematics Acceleration represents the rate of change in velocity over time. Using the terminology introduced earlier, we see that the average acceleration (aav) is: aav (v2 - v1) / (t2 - t1) Δx / Δt Again, we can apply a limit as Δt approaches 0 to obtain an instantaneous acceleration at a specific point in the path. The calculus representation is the derivative of v with respect to t, or dv/dt. Similarly, since v is the derivative of x, the instantaneous acceleration is the second derivative of x with respect to t, or d2x/dt2. Constant Acceleration In several cases, such as the Earths gravitational field, the acceleration may be constant - in other words the velocity changes at the same rate throughout the motion. Using our earlier work, set the time at 0 and the end time as t (picture starting a stopwatch at 0 and ending it at the time of interest). The velocity at time 0 is v0 and at time t is v, yielding the following two equations: a (v - v0)/(t - 0) v v0 at Applying the earlier equations for vav for x0 at time 0 and x at time t, and applying some manipulations (which I will not prove here), we get: x x0 v0t 0.5at2 v2 v02 2a(x - x0) x - x0 (v0 v)t / 2 The above equations of motion with constant acceleration can be used to solve any kinematic problem involving motion of a particle in a straight line with constant acceleration.

Machiavelli vs Islamic Political Thought - 2559 Words

Machiavelli vs Islamic Political Thought Niccolo Machiavelli was a political realist. He thought there were certain skills and characteristics needed to become a political ruler. In his work, The Prince, Machiavelli gives advice on how to be a successful prince, or ruler. Successful is partly based on how powerful a ruler was during his lifetime (reign), but largely based on how much the prince affected the lives, through laws or societal norms, of future generations. Machiavelli was mainly interested in attaining and keeping political power. He believed people were inherently selfish and would, by nature, not respect the law or work for the common good, without civic virtues. The only way to ‘control these human urges was to instill†¦show more content†¦Regardless of how good a ruler Borgia was though, when the time came to install a new pope and it wasnt his father, Borgia fell short and was no longer the ruler. While Machiavelli seemed to put no stock in the role of t he citizen in determining a ruler, he thought rulers could protect their power by evoking the love of their people. But even this isnt enough all the time, because of the question always asked by citizens of its government, what have you done for me lately. The ruler must protect the citizens property, prosperity, family, and well-being. For people to lead happy, full lives, they must be allowed to do what they want, within the guidelines of a state. But this is a cycle easier to maintain, than to begin. For people to do as they wish, there must be guidelines in place, but for guidelines to be established, people have to know what they want to do and what they are unable to do. Here is the reason governments were built in the first place. The group of people chose someone to establish guidelines, because people wanted more than they had. This is the real purpose of a ruler, to help establish a society. Machiavelli was consumed with rulers having and keeping power, by whatever force necessary. This seems to contradict what he is saying about the common good and civic virtues. If the ruler is only interested in power, what care would he have for the people? None, it seems to me.

Marketing Management Selling and Promoting

Question: Discuss about the Marketing Management for Selling and Promoting. Answer: Introduction: According to Hollensen (2015), Marketing involves the selling and promoting the products. Before one jumps into the business it is mandatory that he decide what to sell and where to sell. He added that the planners chalk out the necessary plans to form a network of firms through which the distribution of the product takes place. Let us discuss about the effective distribution channels in detail. Rosenbloom (2012) opined that distribution of products is always the creation of space and time utility. Products should reach at the right place, at the right time and in the proper condition. Otherwise, it fails to satisfy the customers. Basically, it is a process through which the products are transferred from the producers to the customers. According to Iacobucci D (2014), a distribution channel involves the following members: Manufacturer Wholesalers Retailer Consumers Iacobucci D (2014) stated that, before the products are reached to consumers, wholesalers and retailers play the role of the intermediaries who carry the products. The manufacturers are the ones who make the products. Then the wholesalers buy it in large quantities and sell it to the retailers in small quantities. Iacobucci D (2014) added that in many instances, the manufacturers have given the wholesalers the responsibility to transfer goods to the retailers. Rushton et al (2014) opined that another vital task of the wholesaler is to store the large amount of goods to a particular place before they sell it to the retailers. On the other hand, the retailer buys the products from the wholesalers and makes it available for the customers. For example- the manufacturer of the Pixar sells the products to the retailers, i.e. the local movie theatres and then only the customers get it. Oppewal et al (2013) opined that this network of channels might involve another intermediary in the networ k who transfers the goods from the manufacturers to the wholesalers. They are called the agents. During the customers emergency, the agents play a crucial role. They added that it depends on both the nature of the product and the placement of the product to determine the best way to distribute it. Therefore, the planner should consider the following issues before he designs the distribution process. These are as following: Consider the importance of convenience Consider the cost trade-off and customer service Evaluate the major channels of distribution including the number, types, terms and responsibilities. Although the placement of the products is the primary consideration during the distribution channel designing, the marketers need to check the other elements in the marketing mix strategy. These are the price, product, and promotion. Consideration of these parameters helps the planner to design the channel effectively. He can do the planning in various ways. According to Dawson (2014), the categories are: Intensive distribution Selective distribution exclusive distribution Through the intensive distribution system easily transported and inexpensive products are widely distributed. He opined that the marketers use the pull strategy to promote these products directly to the end customers so that they get the product easily. Most of the snack food items are distributed by using Intensive distribution system. While selling the expensive products including cars and appliances, the marketers use the push strategy. As discussed by Wilkinson (2013), it is a limited or selective distribution process. Here the manufacturer exercises his control over the products. However, they impose most control over the products in case of Exclusive distribution. Marketers willing to sell expensive Rolex products use this strategy. Multiple ways and channels also give birth to situations of conflict. Be it the manufacturer, the wholesaler, or the retailer, whoever is large in size, tries to exercise his power over the other members. Undoubtedly, the domination often leads to resentment and lack of cooperation. This is a reason of the collapse in the system. However, these conflicts can be resolved if the businesspersons try to make communication process transparent because it builds trust among the members .It is important to know the others perspectives and for that, they should exchange the personnel for a better understanding. However, third parties can do negotiations. They are the one who understands both and takes the decision neutrally. With the increase of demands and expansion of global market, the distribution system has changed a lot. Online distribution is the best example of it. Nowadays, the decision-makers taking considering the speed and efficiency level of online distribution and they are taking decisions according to that. The advantages of online distributions are- improved communication among the channel members, instant service, cheaper channels, and long-term relationship building with the members. Thus, the products can reach at distant places in shorter time. Reference Dawson, J.A., 2014.The Marketing Environment (RLE Marketing)(Vol. 1). Routledge.

Earth Summary Essays - Planetary Science, Astrobiology,

Earth Summary Earth An Inner Terrestrial Planet Size: About 8,000 miles in diameter Distance: 1 A.U. from the Sun Day: About 24 hours Year: About 365 days General Description: Earth may be the most unique of all planets because of the life forms we know exist here and the way they utilize the Suns energy. The Earth is composed of a great amount of water, mostly in the form of oceans, which make up most of its surface. It also contains various gases, of which make it possible for us humans to exist and is a system that exists between plants and animals here. Core/Interior: The Earth has three layers to it's interior, the inner core, outer core, and mantle. Of these the outer core is thought to be liquid. Like most of the terrestrial planets at birth, the Earth has been molten and undergone some differentiation allowing the heavy material which is consisting mostly of an iron, nickel, and cobalt core making it's density five and a half times the density of water. Surface: Earth probably has the most unique surface with all its various landmasses and water systems. It also has polar caps, volcanoes, and continents that have trees and living organisms moving about on its surface. Much of the tectonic activity on Earth created new landforms and changed other landmasses. Atmosphere: The Earth has one of the most versatile atmospheres because of the way the solar system here picks up water and carries it around the Earth for redistribution. We have a thick atmosphere that consists mostly of oxygen and nitrogen that helps plants and animals survive so well here on Earth. We also have a greenhouse effect that warms our atmosphere and it's surface. Satellites: The Moon is the only satellite known to exist to Earth. Magnetic Field: The Earth has a superior magnetic field due to a core consisting of iron and nickel. Currently the rotation of the Earth and its Coriolis effect help to create this pull of the tides from the oceans. The northern lights or lurora Borealis can be seen at various times in a mystifying view of beauty. When Discovered: N/A Notes: By far the most unique item found on Earth is the Fact that life is known to exist here and successfully grow, cultivate and prosper due to our oxygen content. Mostly due to the fact that we exist in a system of gases that are exchanged between plants and animals. Nowhere else is there such a known diverse system of travel that allows us to explore our planet. Astronomy Essays

Essay about Black Band Disease

Essay about Black Band Disease Essay about Black Band Disease Black Band Disease By Mitchell Jones Tolerating a very narrow range of environmental conditions including temperature, salinity, and solar radiation, reefs are very sensitive to damage from environmental changes. Corals, in particular, are susceptible to a number of diseases including black band disease, white band disease, and coral bleaching. Black band disease was first described in the early 1970s as a black band moving on the surface of star corals and brain corals. It destroys live tissue as it moves over the surface of the colonies, leaving behind bare white skeleton. This disease may kill entire colonies within a matter of a few months, however tissue loss from a colony can be only partial with recovery after the black band disappears. This black band consists primarily of the filamentous cyanobacterium Phormidium corallyticum along with other microorganisms. Research has shown that the death of coral tissue is caused by lack of oxygen as well as exposure to hydrogen sulfide in the tissue adjacent to this black bacterial band The black band microbial consortium consists of an assortment of photosynthetic and non-photosynthetic bacteria that co-exist synergistically. The consortium has three functionally and physically dominant members as well as numerous heterotrophic members whose role in the disease is as yet unknown. The three functionally dominant members are populations of cyanobacteria and sulfide-oxidizing and sulfate-reducing bacteria. The black band disease microbial consortium is structurally and functionally identical to cyanobacterial-dominated microbial mats found in other illuminated, sulfide-rich environments. Black band disease occurs when corals are stressed by environmental factors including sedimentation, nutrient levels, pollution, and high water temperatures but a main cause is cyanobacteria. Several species of cyanobacteria have been found associated with black band disease, the most well-known of which is Phormidium corallyticum. Sulfide-oxidizing bacteria, dominated by Beggiatoa, are present in well-developed bands and exhibit visible vertical migrations within the band matrix. When present on the band surface Beggiatoa appears white due to intracellular

Free to choose - Assignment Example It is natural that different people may form diverse opinions of a person and therefore, the necessity to consider their opinion as a part of identity rises. As the most significant and well-known part of King’s legacy we will consider the famous speech â€Å"I have a dream† to examine people’s attitude towards racial identity. Identity of an individual is formed under the influence of numerous factors – social, political and cultural – that predetermine the way he/she will present him/herself to the society and his/her perceptions of various aspects of life. Moreover, in conditions of the modern culture, people tend to form their identities following the trends or adopting the legacy of certain prominent figures. Pop icons and mass media shape people’s views and behaviors and thus offer a wide range of opportunities for identity expression. Particularly, racial identity is the phenomenon that typically develops in close connection to such concepts as equality and segregation. This aspect of identity implies the way one feels about his or her race and, of course, the way society feels about it. On the other hand, one’s attitude towards certain race-related issue or figure might be subjected to this/her position in the historical and social contexts. Here, the issue of racial ide ntity for ethnic minorities like African Americans attracts much attention in this respect, as it used to be the issue of controversy and oppression for many years before African Americans succeeded in the struggle for their rights. Currently, the figure discussed is Martin Luther King, who made an immense contribution to formation of many people’s racial identity and proclamation of total racial equality. The personality of Martin Luther King is of extraordinary significance in the long struggle against racial discrimination and violation of human rights, which took so many years from the racial minorities.
