Measuring the Resistivity of Copper Wire of Different Lengths In this report I will be writing about the experiment I will conduct on copper wire of different lengths. The dependent variable I will be measuring is the resistance of the Copper wire. To do this experiment‚ one needs to obtain measurements with a high degree of accuracy‚ taking care of the equipment they use and measuring each value to a certain degree of accuracy for all results. The problem with measuring the resistivity of Copper

through a lot of uncertainty‚ trial‚ and error in their daily work. An article from “The Great Influenza” written by John Barry‚ observe scientists and analyze how they deal with uncertainty in their work. Scientists deal with uncertainty everyday in their work. Certainty can make people more confident‚ knowing that something is guaranteed to go right gives everyone strength. Many people can agree that‚ “Certainty gives one something upon which to lean.”(Barry) The opposite of uncertainty is certainty

The article‚ “Themes of Relational Uncertainty and Interference From Partners in Depression‚” turns to the relational turbulence model to clarify the power of depression in romantic relationships. The reasoning for this study is clear in the introduction when the authors‚ Knobloch and Delaney‚ tell of the true quantitative evidence that tracks

The purpose is to prove to people that scientific research is very challenging. Furthermore‚ he discussed how scientists must accept uncertainty in order to find an answer to their experiment; it is very difficult for people to accept uncertainty. John M. Berry is able to characterize scientific research as challenging by showing all scientists must embrace uncertainty in the beginning of his speech‚ undergo tedious work towards the middle of his speech‚ and find the correct solution to their experiment

the typical Nordstrom shopper. 2. Where would you place the demand faced by Nordstrom on the implied demand uncertainty spectrum? Why? Implied demand uncertainty is demand uncertainty due to the portion of demand that the supply chain is targeting‚ not the entire demand. A high-end department store chain such as Nordstrom falls on the high end of the implied demand uncertainty scale. The fashion items that Nordstrom stocks have extremely high product margin‚ high forecast errors and stockout

Uncertainty applies to sectors that the organization deals with on a regular basis‚ the task environment‚ and this must be analyzed along dimensions of stability and degree of uncertainty. • Simple Complex Dimension concerns environmental

with NaOH each time after titrating the unknown acid‚ we need to calculate the difference of the volume before and after each titre. For example‚ the volume used in the first titre would be calculated by: 25-21.3=3.7 mL Uncertainty: (Uncertainty of the previous volume + uncertainty of volume after titration) = (0.05+0.05) =0.1mL Calculating the rest of the titres in a similar fashion (previous volume-volume after titration) the following table of results is obtained: Table 3: Table of the volume
