Balance Lab of a Copper Slug and Sodium Chloride (NaCl) on a Centigram and Electronic Scale PURPOSE/INTRODUCTION The purpose of this experiment is to learn how to weigh a substance on a centigram scale and an electronic scale through direct weight or by weight difference. The hypothesis is that all scales used should show the same weight for a given sample. The experiment should show precision and accuracy of the equipment being used. This will allow a better understanding on how to properly

Determining the accuracy of varieties of pipettes by weighing and finding the density of a liquid Abstract Different varieties of pipettes (P100‚ PR1000 pipettors and a serological pipette) along with a weighing balance was used in this investigation to check the density of an unknown liquid by first finding out what the liquid weighed and plotting a graph of the mass in grams against the volume of the liquid used in micro litres (µl) and finding the gradient of the graph (∆Y/∆X). Most of the

Accuracy is a critical component of evaluating intelligence. Since its inception in the 1950’s‚ there have been about fifteen hundred National intelligence estimates. The estimative nature of NIE’s makes it almost impossible to measure it accuracy and the Intelligence Council has never established a system for evaluating the estimative accuracy. NIE’s are essentially judged in two ways‚ if the NIE is proven correct then the NIE is good; if incorrect then the NIE is bad. Checking the validity of NIE’s

Discuss factors affecting the accuracy of eyewitness testimony. There are factors that affect the accuracy of eyewitness testimony such as emotions‚ fundamental attribution bias‚ face recognition in other races‚ leading questions and many more. An example of the affect factors such as leading questions can have on eyewitness testimonies is the Loftus and Palmed study (1974). It’s has been proposed that we store a series of incomplete memory fragments in our mind. When we need to recall a

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

It has been said that Sparta had two separate histories‚ its own and that of its image abroad...Considering how much was written about Sparta in antiquity‚ it is remarkable how confused‚ contradictory and incomplete the picture is. Partly this is because the mirage is constantly cutting across the reality‚ distorting it and often concealing it altogether; and partly because the Spartans themselves were so completely silent.With respect to our knowledge of the helots in ancient Sparta‚ how accurate

Andrews July 13‚ 2013 * * * * Abstract: In this laboratory we utilize simple measures of physical quantities (for example‚ distance‚ and mass) and use the measurements to calculate or convert other physical quantities (such volume and area). We also use mathematical calculations and formulas to make conversions from one unit of measurement into another unit of measurement (for example‚ a
