Experiment 14: Hooke’s Law and Simple Harmonic Motion Purpose (1) To study Hooke’s Law for an elastic spring (2) To study Simple Harmonic Motion of a mass suspended from an elastic spring Apparatus Helical steel spring with supporting stand and scale‚ set of slotted weights with hanger‚ timer‚ laboratory balance. Theory: Hooke’s Law A spring exerts a force which is given by Hooke’s Law: 1 Fs = - kx where x is the amount of displacement from the equilibrium position.

Results at the end of the trails will be used to compose a rate of law for the reactions. This law will show the “dependence of the rate on the concentration of both H202 and I-. The rate of reaction equation is as follows: Rate of reaction = k [H202]M [I-]N The value of m and n will be calculated from the various runs of the experiment holding either H202 at constant concentration or holding I- at constant concentration Experiment: My lab partner and I first assembled the apparatus that we were to use

A measurement of the difficulty of performing an aiming movement. It states that the difficulty of a movement is mostly correlated with the distance a limb moves and the narrowness of the target. 2. Distance had a little to no effect on movement time for my data. The size of the target had a huge impact on movement time. The

Geometrical Optics: Snell’s Law PHY101 Lab 12 Date: July 23rd‚ 2012 Objective: The purpose of this laboratory activity is to develop a set of experimental procedures that answer questions regarding Snell’s Law and the index of refraction. Ultimately‚ the experimental procedures you develop will allow the index of refraction to be found for water and cooking oil. 1. Explain how to experimentally determine the index of refraction of two substances. 2. Develop a set of experimental

Law Enforcement Police departments have always had their ups and downs. A majority of the time people seem to show a decent amount of respect to our police officers at any level of authority. In this paper we will discuss what some of these issues that police officers have to deal with; how our local‚ county‚ state‚ and federal officers work with the United States Department of Homeland Security; and what improvements can be made to this relationship with the United State Department of Homeland

Determining the Concentration of a solution: Beer’s Law Objective In this lab of Determining the concentration of a unknown solution: Beers Law. We determined the concentration of a unknown CuSO4 solution by measuring its absorbance with the colorimeter. With all the calculations we were able to solve the linear regression Equation of absorbance vs. concentration and the alternate method. Materials Vernier LabPro or CBL 2 interface .40 M CuSO4 solution Computer or handheld

The Difference between Written and Unwritten Constitution are as follows: Written Constitution: Written constitution is one which is found in one or more than one legal documents duly enacted in the form of laws. It is precise‚ definite and systematic. It is the result of the conscious and deliberate efforts of the people. It is framed by a representative body duly elected by the people at a particular period in history. It is always promulgated on a specific date in history. The Constitution

What is land law in English law? Explain how the law distinguishes between whether a thing is a fitting or a fixture or part and parcel of the land itself. Introduction Land is what we step on‚ live on‚ it is very important in our daily life and land in every different area has its owner. That’s how we have the right to say this is mine and we’re the ones who choose what to do with it‚ add something to it or remove something from it‚ change it around or even get rid of it.
