Newton Second Law of Motion Essay

According to newton’s second law of motion, Acceleration is produced when a force acts on a mass. The greater the mass is, the grater the acceleration is needed to move forward. This law basically states that a force applied to the objects changes its velocity overtime in the direction of the force that is applied, the acceleration is directly proportional to the force, as an example, if pushing on an object, causing it to accelerate, and then you push, the same object three times harder, the acceleration will be three times greater and the acceleration is inversely proportional to the mass of an object, if you push equally on two objects, and one of the objects has five times more mass than the other, it will accelerate at one fifth of the object. SUV’s have the greater mass than the car. So SUV’s need more force than light car to move forward in the direction the force is applied, we can say that SUV’s need more force to act than a car, for example driving an SUV and light car at the same velocity, the force needed for car would be less than the SUV and the car would run faster than a suv as it need less force than an SUV. SUV requires more fuel than a normal car. A Car could run faster than an SUV and it even requires less fuel. Therefore, the more mass the object has, it requires more force to make it move forward and to act on it. Newton’s second law of motion states that the heavier objects require more force to get them moving but smaller objects or lighter objects require less force to actually get them moving. The formula that is used is force equals mass times acceleration. For example if you throw a 5lb weight stone and a 2lb weight with the same amount of force the 2lbs weight will travel faster than the 5lbs weight, That is because there is less mass to be moved, A truck hits a car and allows the car to move forward. The truck provides the force and the car’s mass, and the acceleration is how quickly the car (mass) moves forward. The larger and heavier the car mass is, the more force it takes to move forward. If the car has very less mass it move’s forward quicker than the car with more mass. Thus, we can say that more people would prefer a car than a SUV’s because of it’s mass and fuel efficiency that is required which is very less in consumption in a car than compared to SUV’s.

Art History Formal Analysis – Comparison

Formal Analysis Paper The pieces Ann Whitley Russell, done by an unknown artist in around 1820 and Lady Frances Knowles, also done by an unknown artist, in the mid-late 17th century are both examples of portraits that portray the sitters in diverse yet insightful ways to viewers. Both Ann Whitley Russell and Lady Frances Knowles are works of art composed of oil paint on canvas. Although these portraits are different, the aspects of space, color, and composition are all important elements that must be considered while comparing the woman in these two pieces.The significant element of space comes into play while analyzing the portrait of Ann Whitley Russell. The figure of Ann Whitley Russell herself is very flat and appears to be two dimensional, rather than three. The two dimensionalism of this portrait says something about the skill level and amount of training that this unknown artist holds; they were most likely self-trained. Since there is a shallow depth of field in this piece th e viewer is automatically drawn to the sitter, Ann Whitley Russell, who is positioned in the foreground of this piece.Ann Whitley Russell is illustrated sitting on a chair with a decorative cloth draped over the left arm, which is positioned in the middle ground of the portrait. The background is monochrome, blurry and is indistinguishable to make out other than the column to the side of the portrait. The column looks as if the artist based it on Greek and Roman architecture due to its rounded appearance and indented texture. These columns would have been found in Europe throughout the early to mid eighteen hundreds, which was around the same time that this portrait was created.By including this type of column in the background the artist may be trying to portray the sitter, Ann Whitley Russell, as someone who is elite, wealthy and privileged enough to live in a place where this type of architecture exists. Although the artist made this column visible, it is still impossible to dete ct a specific setting in the background of this portrait. Furthermore, although the significance of the element of space also effects how viewers perceive the portrait of Lady Frances Knowles it does so in a different way.The viewer is automatically drawn to the center of this piece, which is the vivid three-dimensional figure of the sitter, Lady Frances Knowles. While studying the portrait Lady Frances Knowles I was able to detect a clear distinguishable foreground, middle ground and background. The artist positions the sitter in the foreground of the piece sitting on a stone bench with one arm resting upon the ledge of a stone fountain which is positioned in the middle ground.The stone fountain in the middle ground which has a statue of a Roman mythological winged figure attached has water flowing down from it and appears to be solid in space and volumetric due to this. The statue of a winged figure appears to be an angel, which is a symbol of love, peace, and protection. The back ground of this piece has trees with flowering leaves which may be where the flowers upon the lap of Lady Frances Knowles and the bench she is sitting on came from.The background seems to be slightly shallower compared to the sitter who is lifelike and three-dimensional. The background is less defined than the sitter is however the trees, fountain and flowers are distinguishable and give evidence that she must be sitting somewhere outside. The artist may have positioned the sitter somewhere outside in order to show the importance of nature and natural beauty because the sitter herself is so naturally beautiful.The artist of Lady Frances Knowles and of Ann Whitley Russell both use space to visually demonstrate what type of person the sitter is in the portrait, even though the way the space is represented is different in both. Another very important aspect that must be considered during the analysis of the portrait of Ann Whitley Russell is color. In this portrait the artist tends to u se a narrow array of colors that are bland and monotonous. The artist uses the same colors of black, white, brown, grey and red throughout the entire piece.The background is incredibly dull and the shades of brown get darker as it moves further away from her head. In this portrait the red is only bright and exciting color, it is found used for the plain velvet looking chair, the red accents on the cloth draped over the chair, the stone in the center of her necklace and the thin line of lipstick on Ann Whitley Russell’s lips. The black of the sitters dress contrasts her pale white skin and due to the incredibly dull background color more attention is given to her.By using these colors the artist shows how although Ann Whitley Russell is a woman of great wealth, she is a plain woman and instead of embellishing her with vibrant colors he focused on maintaining the sitters true essence. Additionally, while analyzing the portrait of Lady Frances Knowles the importance of color is also used however it is to express different meanings. It is easy to see that the artist of this piece finds color very important due to the vast color pallet he uses in order to contrast the colors of the sitters dress and her skin tones.The pallet consists of a diverse amount of blue, white, pink, red, grey, brown, and black shades, which are used to illustrate the sitter and her surroundings. The artist uses flowing brush strokes to engage viewers in Lady Frances Knowles, a strong example of these brush strokes can be seen in the sitters long brown flowing hair that she is trying to show off. The background of the portrait, which contains a variety of red and pink accents against a darker black background, deeply contrasts the white and pink shades of the sitters skin tone and the shades of blue on the sitters dress.Shadowing is used on the skirt and sleeves of the sitters dress to create realistic folds and wrinkles in the expensive fabric. The shades of red and pink are used fo r the flowers held by and surrounding Lady Frances Knowles, and are emblems representing femininity, beauty and fertility. The artists use color in contrasted ways in the portraits of Lady Frances Knowles and Ann Whitley Russell in order to illustrate the sitter’s unique personal attributes. The aspect of composition is one of great value while discussing the portrait of Ann Whitley Russell.Ann Whitley Russell’s figure takes up the majority of the piece and viewers are pulled into the portrait by the way the sitter’s head is slightly tilted in a contrapposto pose causing her gaze to fall upon us. The way the artist positioned the sitter with both of her arms resting over one of the arms of the chair seems uncomfortable and awkward, however this may have been seen as a proper way of sitting in 1820. Ann Whitley Russell’s portrait is a half body portrait from the waist up rather than a full body portrait that would have been more expensive at the time.The a rtist also focuses on the importance of lines by making them very defined so the viewer is able to depict where everything is easily. Due to the blurred and empty space in the background the sitter appears to be placed in an empty environment the artist may have done as to draw more attention to the subject (the sitter). Moreover, while analyzing the use of composition again in the Lady Frances Knowles portrait it is evident that it’s use is different.The artist gains the viewers full attention by the way the sitters face is held up gently by her hand and her soft eyes connect with the gaze of the viewer, drawing us even closer to the work of art. The way the artist positioned the sitter looks as if the sitter is going to get up at any moment due to how comfortable and relaxed her position is. The figure is directly centered with the background however her arm resting on the edge of the fountain on the side brings the main focus from herself to the intricate fountain.The back ground of the portrait is cluttered and the brush strokes are heavy and dark so the viewer will keep their focus on the sitter rather than the background. The proportions of the sitter in the portrait are accurate and almost entire the body of the sitter is portrayed, showing how she is willing to pay more for something more elegant. The artists for Ann Whitley Russell and Lady Frances Knowles both communicate diverse and very distinct characteristics about the sitter to viewers through the use of composition.After analyzing both of these portraits in excessive detail I have found that although they are unique in a variety of ways, both artists concentrations of work are the same. Some contrasts between the two portraits are that Ann Whitley Russell is two dimensional with a bland color pallet and is a half body portrait; while Lady Frances Knowles is three dimensional with a broad expanse of a color pallet and it is almost a full body portrait. The use of the elements space, color, and composition all influenced how the artists created the portraits of Ann Whitley Russell and Lady Frances Knowles and the themes within them.The unknown artist of the Ann Whitley Russell portrait used all three elements in order to illustrate how the sitter is a simple woman yet wealthy and elite as well. In the portrait of Lady Frances Knowles the artist, who is also unknown, uses these aspects to portray the natural beauty, femininity and wealth. Both themes are similar because they relate to how both sitters for each portrait aspired to be portrayed by the artists as attractive and wealthy.

Assignment - Math Problem Example The multiple regression analysis helps in examining relationship between one continuous dependent variable with one or more continuous independent variables. The regression analysis uses numeric data for analysis. In the field of public affairs, a researcher usually has to study various variables to quantify effect of one variable to other. In the case researcher does not include other factors affecting a particular variable it would lead to a particular bias known as ‘omitted variable biases. Multiple regression analysis helps in removing this bias by dealing with large number of explanatory variables. The study of these variables helps in asserting hypothesis wrong or vice-versa. This helps in identifying and generalizing the research findings for a larger population. The sample size needs to be sufficient for the analysis. The t-test or ANOVA is used with the data where variables are categorical and continuous. The mean scores of the groups are compared in order to understan d the difference between the groups. In the case of public affair, this analysis helps to test the probability differing two means. The correlation studies help in conducting rigorous research that can be done in order to understanding the nature of relationship between the variables. The correlation study helps in testing the validity of the research. The paired variables are linked with each other. The scatter plot produced to graphically present the correlation of a variable with the help of a linear line. The more is the gap between points from the straight line, the higher will be the weakness of relationship between those two variables. The direction refers to the slope of the scatter point. The variables can be in positive or negative relationship. The difference in one variable will have corresponding changes in the other variable. The positive correlation provides us information about the nature of change towards one another. The negative correlation shows that the change i s opposite direction. The correlation method is an appropriate method to examine the relationship of meaningful data. The data should be quantifiable. The correlation cannot be examined using categorical data. The correlation and regression studies are used for testing hypothesis and determining cause-and-effect relationships. The associated variables are studied for the association and the nature of association. There are various benefits of correlation test. This can help in predicting and helps in validating. This is a reliable method and helps in verifying theory. The Pearson coefficient is used when the variables are continuous. This requires one independent and one dependent variable. For example if there is a need to study the level of awareness of a social-environmental sustainability programs among different genders and its relation with success of program in particular geographic region. The level of awareness and the difference of awareness among the population can be und erstood by the correlation study. The regression analysis will help in identifying if the level of awareness was linked to the level of success of program. The t-test can help in accepting or rejecting the hypothesis that success of progra

In order to increase their revenue this company should market through digital media. This can also be categorized as low hanging strategy. I strongly recommend the use of this digital media i.e. online marketing, blogs, forums, social media etc as customer behavior is changing every day and people (doctors) mostly use internet as the source of information for new drugs. This would definitely have positive effect on the company as it can have direct contact with customers through this. This can result in great financial improvements (Abbott 2011). DEAN FOODS: Dean foods is an American food company which mainly deals in milk and dairy products. Marketing plan for dean foods can be advertisements through newspapers or pamphlets, door to door service and change in the way of presenting the product. All these are very common yet effective ways of marketing. Advertisements in newspapers and door to door service both can lie in low hanging fruit category. The success of the change in the presentation can be risky because it depends upon the consumer’s taste. ... It is one of the top brands worldwide for women’s undergarments. It needs to be very innovative when it comes to its marketing strategies and it is already doing very well in it. New models should be hired every year so that consumers are not bored by the same faces. More and more ads should be put in all kind of magazines instead of just fashion ones. Any new product that comes up should be immediately advertised. All these will help Victoria’s secret to continue being a monopoly in lingerie business. Hiring new models can be low hanging fruit for the company. Putting ads in different magazines can be both low hanging fruit and home runs. Hiring new models can be a little risky because the success of it actually depends upon customer’s taste. I would strongly recommend my second advice of advertising the product in all kind of papers and magazines because this would also target customers who do not read fashion magazines. It will increase the demand and will enh ance public relations (Business Week 2006; Franco 2000). BIBLIOGRAPHY: Dean Foods Company STRATEGIES: ONE BIG SECRET.

Case Study Example A company that combines teamwork and motivation enjoys increased employee productivity that accrues from employee job satisfaction. Profit sharing is one of the motivational techniques that Semco uses. Semco gives one-quarter of the profits of its individual divisions to its employees. Also, Semco uses worker participation is an important element of employee motivation. Semco’s employees are involved in the processes of planning, decision-making, and implementation of business plans and ideas. Semco’s employee participation is captured in it policy manual that says, â€Å"Our philosophy is built on participation and involvement. Do not settle down. Give opinions, seek opportunities and advancement, always say what you think. Doesn’t be just one more person in the company† (Killian & Perez 1998). Semco’s use of shared profits and bonuses as a motivation technique is similar to that of SAP. SAP’s other monetary benefits to its employees are in terms of life assurance and pensions and Semco extends bonuses to its employees in terms of house allowances. The freedom allowed Semco’s employees resemble closely the freedom allowed SAP’s employees (BBC 2012). In both companies, there is flexibility in terms of working hours and employees are accorded the discretion to modify work to suit their convenience. A striking similarity between the two companies is the structure of their management. Their managements are not hierarchical and managers are not feared like in other organizations. A notable difference between Semco and SAP is that SAP extends its employee monetary benefits to their families. This way, SAP combines employees’ personal life and their work life (BBC 2012). On the other hand, Semco separates the two and any benefits that reach employees’ families are not purposively channelled. Semler believe that mixing employees’ work life with their family life is not good for business. Semler belief that combining the two can affect an

Critique of a research paper qualitative in nature Assignment

Critique of a research paper qualitative in nature - Assignment Example The sample sizes of GPs and care home professionals were 3 and 8 respectively. Sample sizes of care home residents and family members were 23 and 2 respectively. On introspection from an academic researchers’ point of view, these sample sizes leave some ambiguity regarding the procedure adopted in selecting the sample. The researcher has not clarified which scientific method of sampling was adopted in selecting this sample. This raises a doubt about the authenticity and validity of this study. One definition of validity in research is that â€Å"we have reached the goal of validity when our statements or conclusions about empirical reality are correct† (Engel and Schutt, 2005, p.18). This research exercise is ambivalent, when considered from the angle of â€Å"measurement validity, generalizability, and causal validity,† which are the three aspects of validity as far as social science research is concerned (Engel and Schutt, 2005, p.19). This is so because no pro per measurement has been made by this research exercise, it has very limited generalizability because of the erratic sampling and also the cause of change has not been properly identified in terms of dependent variables other than the adoption of LES. There could be locally specific and institution-specific causal factors. Another matter of concern is that the sample size seems to be too small to be in agreement with the existing social science research norms. It has been observed, â€Å"you would need a very large sample in order to have a chance of finding an impact of social work† (Gorard, 2003, p.61). Though this notion has been somewhat changed after approval for qualitative research with smaller sample sizes grew, the extremely small sample size (with no consistency while selecting respondents from each category) in this research limits its scope of application to the narrow geographical area in which it is conducted. And it has to be reminded, â€Å"by convention, [â € ¦] thirty comprises the magic number for the allowable minimum sample size† (Seidman, Seidman and Abeyesekere, 2001, p.174). In this research, it can be seen that no sample from any of the categories of respondents chosen by the researcher meets this criteria. The researcher has said that, the â€Å"interviews were [†¦] open-ended and required participants to reflect on their general experiences of GPs and the ease of accessing support, and comment on any improvements to the service† (Briggs, 2011, p.6). Though open-ended questions are more suitable for small sample sizes, it has to be remembered, â€Å"open-ended questions are far more difficult to code† (McNabb, 2010, p.118). The researcher in this particular study has not given any information on the data collection procedure and also the coding of the data thus collected. This has badly affected the credibility of this study. At the same time, the research has fulfilled the ethical conditions require d in such a venture, by following the â€Å"established procedures† as prescribed by the British Sociological Association (Briggs, 2011, p.6). The researcher has maintained transparency by admitting that the â€Å"review [that was carried out] was not commissioned as research and therefore ethical approval was not required† (Briggs, 2011, p

Societal Perception Of Foreign Business In Nigeria Dissertation - 1

Societal Perception Of Foreign Business In Nigeria - Dissertation Example Such permission can only be granted by the local communities like the Ogoni. The social perceptions towards the foreign companies operating in Nigeria deteriorated as communities became displaced and their resources forcefully are taken to accommodate the oil fields. The societal perceptions of the oil-led development in many countries have many consequences. Some of these consequences include slow growth, inequality, and unemployment. Countries that depend on oil production are characterized by poor governance, high rates of corruption and high instances of conflict. This has added to the notion that foreign companies are exploitive and unfriendly. Norway has used the benefits of North Sea petroleum to develop its economy. Nigeria and Angola have been suffering from poor management of the same resource. In Nigeria, the disparity between poverty and oil wealth is notable (Parker 2006). The same trend has been observed in Venezuela. Foreign companies like Shell-BP for partnerships with domestic elites with an aim of protecting their interests. The multinational has been blamed for the inequalities created by the oil-led development. In the Niger Delta region, exploration began in 1958. The compensation of the land acquisition in the delta region has aided only a small group of people (Apter 2005). The environment and the local economy remain devastated. Gas flaring has permanently destroyed food crops and the only source of livelihoods for the local communities (Parker 2006). Barren farmlands and destruction of drinking water have created tensions between the local communities and the foreign mining companies. Thousands of villagers have been killed through explosions and raptures.
