The spring constant Manuel Cereijido Fernández – UO237242 PL-4 -----------------------------------------------------------------------------------1. Objectives The main objective of this experiment was to determine the spring constant using the dynamic method. 2. Theoretical fundamentals On the one hand‚ when a spring oscillates‚ the movement which describes can be classify as a simple harmonic motion. Therefore‚ its position‚ velocity and acceleration equations respect the time will

Held to Ransom Alone and seemingly lost‚ I was heading down the street unaware of my destination. There was an elderly lady standing beside me‚ who‚ with immense concern‚ asked me “Where are you going?” I replied “I’m going for a stroll.” The sight of other people roaming the streets comforted me and gave me a sense of security. A colorful‚ vivid‚ neon sign reading “Game Lounge” just across the street took my heed‚ and intrigued me to go inside. As I began walking I fell headlong onto the sidewalk

father of “Modern Portfolio theory”‚ developed the mean-variance analysis‚ which focuses on creating portfolios of assets that minimizes the variance of returns i.e. risk‚ given a level of desired return‚ or maximizes the returns given a level of risk tolerance. This theory aids the process of portfolio construction by providing a quantitative take on it. It integrates the field of quantitative analysis with portfolio management. Mean variance analysis has found wide applications both inside and outside

Mean-Variance Analysis Mean-variance portfolio theory is based on the idea that the value of investment opportunities can be meaningfully measured in terms of mean return and variance of return. Markowitz called this approach to portfolio formation mean-variance analysis. Mean-variance analysis is based on the following assumptions: 1. All investors are risk averse; they prefer less risk to more for the same level of expected return. 2. Expected returns for all assets are known. 3. The

The Equilibrium Constant of an Ester Hydrolysis Reaction CHM 152LL Section 33263 March 28‚ 2014 John Weide Abstract: The purpose if this experiment is to determine the equilibrium constant of an unknown alcohol. In this experiment unknown alcohol number three and unknown ester number three were used. The equilibrium constant was found by titrating a series of reactions containing H2O‚ HCl‚ and the unknown ester with only the last solution containing the unknown alcohol

There is also an issue regarding to their supplier‚ Pingdingshan that supply a low quality coal but in a higher price than the prior year. Therefore‚ in our case study‚ we conclude that we need to do a variance analysis to better understand the plant performance compared to the previous year. The main problem in

What drives a person to be successful? There are some who say that it is due to extrinsic factors‚ or what environment an individual is placed into will have a major influence in their decisions. Others believe that no matter what environment someone is placed in‚ it will not influence their decisions‚ rather‚ it comes down to how mentally healthy the individual is.
