(JUNE)‚ Spring 2011‚ 9(2):A71-A74 An Undergraduate Laboratory Exercise to Study Weber’s Law Jameson K. Holden‚ Eric M. Francisco‚ Zheng Zhang‚ Cristina Baric & Mark Tommerdahl Biomedical Engineering Department‚ University of North Carolina‚ Chapel Hill‚ NC 27599. Weber’s Law describes the relationship between actual and perceived differences in stimulus intensity. To observe the relationship described in this law‚ we developed an exercise for undergraduate students‚ as experiential learning is an integral

Thermodynamics-Enthalpy of Reaction and Hess’s Law Purpose To demonstrate the principle of Hess’s Law and to find the heat capacity of the coffee cup calorimeter using three different reactions. Data Tave = (46.4-45.2)/2 = 45.8 qwater = -(100g)(4.184)(46.56-45.8) = -318 J Ccal = 318J/(46.56-21.2) = -12.53J/g*C Tinitial = (27.1+23.8)/2 = 25.45 qrxn = -(100g)(4.18)(38.43-24.45)+(-12.53x12.98) =-5400J/.1mol(1J/1000kJ) = -54.0 kJ/mol Tinitial = (26.0-24.5)/2 qrxn =-(100g)(4

Conclusions Managers involved in helping their organizations improve quality are frequently puzzled over which approach to use. Some organizations adopt an eclectic approach using components of the three philosophies and combining what they consider to be the best from the best. Other organizations select the Crosby‚ Deming‚ or Juran approach and remain loyal to it; all their education‚ training‚ and implementation efforts reflect support for that one approach. There are organizations that switch

Lab 2: Equipotential Lines and Lines Of Force Purpose: The purpose of this lab is to find the electric current when passing through conductors of different shapes and sizes. Also to gain a general knowledge of the laws governing the flow of current through extended conductors is another objective for this experiment. In this lab we are to experiment with the lines of force and equipotentials. We are also to find out vector field and the relationship between the lines of force and the electric field

October 1‚ 2013 Chemical Reactions of Copper Objective The objective of this lab is to convert copper (Cu0) “in a series of reactions to various compound containing copper as the Cu2+ species” (CHM111 Laboratory Manual) in order to prove the Law of the Conservation of Mass. Introduction In this experiment‚ we took a look at how copper (Cu0) reacts with different substances to get an end result where it is transformed back to its original state. There were five different reactions that involved

experiment is to apply Beer’s Law by analyzing samples provided by Q laboratory to determine their absorbance and prepare a Beer’s law plot. Molarity of these samples was also calculated to determine concentration and percent error rate. Students also analyzed the concentration of blue dye #1 to determine the concentration of blue dye #1 in a commercial blue dye drink. Procedure Exercise #1 Step #1: Convert %T (Table 1) to absorbance and prepare a Beer’s law plot using the data. Step #2:

Eternal Law and Human Law As humans live in this world‚ laws and regulations are strictly enforced for the justice‚ safety‚ and rights of the humans. Whether those laws are eternal or temporal‚ all laws require standards. Saint Augustine’s On the Free Choice of the Will discusses these standards and defines what each laws mean. Most importantly‚ Augustine argues that eternal law is necessary for temporal law to exist and for the nation to function properly. I agree with Augustine’s argument on

Abstract In this assignment‚ lead compensator is implemented to reduce the percentage of peak overshot to less than 5% and the settling time to 2 second with 2% accuracy. First of all‚ to implement lead compensators into a circuit‚ a pole–zero pair is introduced into the open loop transfer function. Lead compensator is a component in a control system that improves an undesirable frequency response in a feedback and control system. Besides that‚ it also provides phase lead in its frequency response

F. CONCLUSION As before we jump into conclusion‚ here will be described a list of entrepreneurial competencies owns by our chosen entrepreneur‚ Mr. Muhamad Yasin. The first entrepreneurial competency shows by him is initiative. Initiative means the ability to assess and initiate things independently or the power or opportunities to act and to take charge before others do. Mr. Yasin saw the opportunity‚ just like the people does. Yet what is making him difference and succeed is initiative value in

Discuss the relationship between law and morals and whether law should uphold moral values? Phil Harris in an introduction to law defines a society’s ‘code of morality’ as a set of beliefs‚ values‚ principles and a standard of behaviour. A compliance with these rules is not compulsory and not required by the state. People are influenced by their family‚ friend’s religion. However‚ they could consider from themselves what they believe to be moral or immoral in their view‚ because a society is pluralistic
