Conservation of Mechanical Energy

Background: Kinetic energy is said to be the energy of motion. Kinetic energy can be defined through this equation: KE=12mv2 (equation 1) Where m is the mass of the object in motion, and v is the velocity of the moving object. Potential energy is the energy associated with the forces that depend on the position…

The Ordered Universe Assignment

1. Why was the Ptolemaic system accepted as an explanation of celestial motion for over a thousand years? What did it explain? What system challenged the idea that Earth was the center of the universe? The Ptolemaic system says that the Earth is the center of the universe. Everything else surrounded the Earth. The Copernican…

Mass Society Theories, Social Responsibilty Theory and the Media

The first half of the twentieth century played a vital role in the state of the present media. The century commenced with the influx of new forms of media as modernization uncontrollably invaded all social forms. The dominant medium of the nineteenth century, the newspaper, sustained its power at the beginning of the century. Moving…

Separation of a Mixture of Solids

I really enjoyed this lab. After reading the introduction I started by making my own flow sheet of how I thought this lab would work. I was reminded about solubility which is defined as the amount of the solute that will dissolve in a given amount of solvent and that the extent to which a…

E-media fast report

Being a person who is working with e-media every day, my expectations for a week without any of these sources were rather pessimistic. But still I considered it a nice tool to see the dependency on e-media, which a big part of the population is suffering from. As the week of sacrifice began, the problems…

Separation of a Mixtures Lab Report

The purpose of the experiment was to separate an initial heterogeneous mixture composed of 5.00 grams of salt, 2.00 grams of sand, 50.0 mL of water, 15.00 grams of pebbles, and 1.00 gram of iron filings, and leave as much salt as possible remaining. Using separation techniques including magnetizing, evaporation, filtration, etc. the heterogeneous mixture…

Stoichiometry Precipitation

The calculations completed for this experiment include determining the amount of Na2CO3 needed to do a full reaction. This was calculated through stoichiometry calculations: Molar mass was first calculated for CaCl2*2H2O Ca = 40.078g Cl2 = 35.453g*2 = 70.906g 2H2 = 1.00794g*4 = 4.03176g 2O = 15.9994g*2 = 31.9988g 40.078g + 70.906g + 4.03176g +…

Bayfield Mud Company

The Bayfield Mud Company has had some problems with their 50 pound bags of treating agents. They sent shipped some bags to Wet Land Drilling, Inc. that were found to be short-weight by approximately 5%. Wet Land first did their own research on how many bags were short and by how much. They randomly sampled…

Bayfield Mud Analysis

The Bayfield Mud Company has had some problems with their 50-pound bags of treating agents. They sent shipped some bags to Wet-Land Drilling, Inc. that were found to be short-weight by approximately 5%. Wet-Land first did their own study on how many bags were short and by how much. They randomly sampled 50 bags and…

Investigating circular motion

By plotting the graphs it can be observed the y axis is equal to v” and the x axis is given as r (radius), the gradient is given by (y2 – y1) / (x2 – x1). By working out the gradients it can be seen that the gradient for 50-gram masses is approximately 26, whilst…

Conservation of Momentum Practical Write Up

AIM: To investigate if momentum is conserved in two-dimensional interactions within an isolated system. HYPOTHESIS: Without the effects of friction the momentum will be conserved in the isolated system. In all three experiments the momentum before the interaction will equal the momentum after the interaction. METHOD: An air hockey table was set up and a…

Synthesis of Organic Aspirin

ABSTRACT: The purpose of this experiment was to find out how a reaction undergoes for a globally known painkiller called aspirin, and to become familiar with achieving successful yields. Aspirin is synthesized from salicylic acid and acetic anhydride. Those two chemicals are mixed together along with sulfuric acid to form a crude solid. Filtration is…

Amusement Parks Are A Great Place

Amusement parks are a great place to see Newton’s laws of motion in action. Choose your favorite ride and describe the parts of the ride that illustrate each of Newton’s laws of motion. You are only required to give a written description; however, if you would like, you may draw and label a picture in…

Module Five: The Sacraments

Trace the development of the celebration of the Sacrament of the Eucharist from the early church with special reference to how it is understood and celebrated in the Church since the Second Vatican Council. Assignment: 3. Trace the development of the celebration of the Sacrament of the Eucharist from the early church with special reference…

Global Logistics Management

Suppose that a manufacturer of men’s shirts can produce a dress shirt in its Houston, Texas plant for $8 per shirt (including the cost of raw materials). Chicago is a major market for 100,000 shirts per year. The shirt is priced at $15 at the Houston plant. Transportation and storage charges from Houston to Chicago…
