Objective: We will determine the acceleration of the weights of an Atwood’s Machine, both experimentally and theoretically. We will attempt to verify Newton’s Second law which is a mathematical statement relating force, mass, and acceleration. Newton’s Second law states that acceleration, a, is directly related to net force, F, and inversely related to mass, m. Naturally this give F=ma. Using the Atwood’s Machine experimental acceleration data (for 10 different runs with 10 different combinations of masses) will be gathered and compared to the theoretical acceleration which is predicted by Newton’s Second Law using a modified version of F=ma. The only two variables in this system system that we will control are the the two masses. We†¦show more content†¦The inversely proportional relationship between total mass and acceleration is also shown in our graph. I took the liberty of plotting the non-constant mass by F vs. aexp. Which clearly showed that with an increase in total mass resulted in a gradual decrease of the acceleration of the system. There were several sources of error in our experiment. But none affected the ability for a relationship between mass, acceleration, force to be drawn. The largest error was the one mentioned above. But its source was the easiest to account for. We mis-imputed the value of the spoke length into DataStudio. Luckley this mistake was easily remedied due to the design of the pulley. The electronic eye was recording a time that was exactly half of what it should have been. This time data produced an acceleration that was exactly double what it should be. Therefore this was issue was easily remedied by dividing the times by 2. Other sources of error were due to the frictional forces in the pulley system, also the masses of the weights might not have been perfect. Air resistance was a major player when the difference in masses was large, therefore acceleration was high. The weights could have b een verified to eliminate that error, and more advanced physics could have been used to take into account the friction of the pulley and the air resistance.

Application Letter For The Master Of Public Health Program...

My name is Pratik Dey Sourav, and I am applying to the Master of Public Health program at New York University. The bulk of my professional experience has been as a physician working in Bangladesh, which incidentally was where I first witnessed the power and impact of a well-executed public health program. I recently moved to the United States and am now seeking an education in Public Health to address the gaps in my profile as well as give me access to career opportunities in public health administration. My long term goal is to improve the public health environment in Bangladesh. Working as a medical professional in a developing country opens one’s eyes to how parts of the world can still lag behind what one assumes to be the ‘status quo’ of community health . Even so, focused efforts of well-meaning professionals can truly make a difference in the lives of communities that are otherwise hard-to-reach. Bangladesh has had its fair share of challenges in the public health sector that are still to be surmounted. That said; recent initiatives in public health have yield astonishing improvements in maternal health, infant mortality rates and general community health awareness. In particular, during my first WHO-sponsored project in which I studied maternal mortality in rural Bangladesh, I surveyed one of the most underdeveloped and underprivileged areas of Bangladesh, called ‘Palash Bari’. What I saw there was nothing short of amazing. A village, where even a basic necessityShow MoreRelatedCareer Plan Assignment.

Art Work Analysis Essay Example For Students

Art Work Analysis Essay The name of the artwork that I have chosen to analyze is Home, Sweet Home by Winslow Homer. Homer first came to national attention during the Civil War with his accurate, vivid sketches of life at the front. As an artist-reporter he accompanied the Army of the Potomac in the Peninsula campaign in Virginia, observing camp life and some combat. While Homer drew a few traditional military scenes, such as bayonet and cavalry charges, he mostly depicted the utterly unheroic day-to-day activities of ordinary soldiers behind the lines. Homers Civil War drawings and paintings showed not only accurate down-to-earth details of soldiers everyday lives but touched on themes of isolation, morality and natures adversity, which he dealt with in his later art. To this day, these wartime images remain powerful reminders of this nations most tragic conflict. In the extraordinarily richly painted Home Sweet Home (circa 1863), the sky and background resemble a classical landscape with its cloudy blue coloration and small groups of figures in the Background. When I took a closer look and upon further research I found out that, one of the dark figures turns out to be a brass band playing the popular Home Sweet Home tune of the title? In contrast, the foreground is divided off by the light brown of a hanging cloth which merges into the darker browns of the tents and earth the whole scene seeming to concentrate on two soldiers in blue uniforms. As others have observed and stated it is to be perceived listening to the music. Their thoughts Im sure are of distant homes. But Homer subtly subverts that idea. They gaze down on what has now become their home with their army gear outside a small low tent with a single boot sticking out from the dark interior. I like to appreciate the little details that Homer throws in that make it all that much more realistic like the metal pot steaming away on glowing embers, or the two hard biscuits that lie on a metal plate. My feelings about this visual art would best be described as realistically appreciated; I truly feel that Winslow Homer captured the essence of the trying days of soldiers that might not be full of battle or loss. He managed to capture what life was like for them on the good days all while the hints of home sickness and loneliness peered through. I couldnt agree more with the statement made by Paul Mitchell, in an art review about Winslow Homer when he said The vitality, freshness of vision, largeness of form, resonant color harmonies, superb decorative values and the elemental themes underlying his art make Winslow Homers works as alive today as when he created them a century ago. I can certainly relate to this statement especially with the war in Iraq currently, and being a soldier myself.
