Error Analysis: Force constant in springs Maria Loraine Menorca National Institute of Physics‚ University of the Philippines Diliman‚ Quezon City lorainemnrc@gmail.com Abstract This experiment aims to fully understand the analysis of possible errors in the measurement of the force constants in different spring systems. Springs can be utilized to store and release energy. According to Hooke’s Law‚ the response of a spring to external forces is characterized by the equation F = -kΔx. In this experiment

Equilibrium: Finding equilibrium constant‚ Kc 1 Abstract Chemical reactions are accompanied with formation of products. A reaction can be reversible or forward according to the rate of formation of product. However‚ they do not reach completion and the mixture remains in equilibrium. This theory help us the study the existence of equilibrium constant‚ Kc. This constant is temperature dependent‚ and it must be calculated at given temperature. This equilibrium constant is used to improve the

English Constant Gardner Directed by Fernando The Film ‘The Constant Gardener’ Directed by Fernando Meircelles‚ Is fill confusion‚ entertainment and love. I thought the film was very good in the techniques the director used‚ but was hard to get my head around. ‘The Constant Gardner’ would be thought to be about gardening‚ but it’s just based around it. The concept of gardening is the story line of the movie. Two main characters Tessa and Justin are in love‚ but don’t know each other as well

Writing Assignment #2 27 April 2011 Death Constant Beyond Love Gabriel Garcia Marquez’s short story‚ “Death Constant Beyond Love” depicts the vulnerability and helplessness of a human when dealing with two of the most enigmatic parts of life. The background of corruption‚ poverty‚ and the political campaign become rather insignificant to the broader themes of love and death. Marquez expresses the confusion‚ power and diversity that come with the feeling of love and how ever changing it can be

Fernando Meirelles’ “The Constant Gardener” is a complex thriller/love story‚ based on the novel of John le Carre‚ containing a heavy use of non-linear story weaving‚ flashbacks and flash forwards. The main character‚ Justin Quale‚ is shown as an unassuming‚ almost passive person‚ while his wife‚ Tessa‚ is shown as assertive‚ and almost aggressive. Justin and Tessa are important to the film‚ because the contrast between their characters helps develop the theme of the never-ending work of gardening
