Rick Hess was diagnosed with diabetes in his early 40s. When he was in medical school‚ he participated in a study that analyzed insulin. His results were low and a little out of the normal levels. However‚ if he would have known more about the results like they do now‚ it would have predicted he would have become diabetic. In addition to being a diabetic‚ Rick has also had to overcome cerebrovascular disease in his 70s. Rick Hess is now 76 years old. He attended the West Virginia University to

is directed perpendicular to the surface. (b) Friction Force‚ f : In addition to the normal force‚ a surface may exert a frictional force on a object‚ directed parallel to the surface and opposite the motion or impending motion of the object. f s = µ s n - static friction‚ maximum friction before the object begins to move. n ff kk ==µµk k n - kinetic friction‚ friction on a moving object.

NaOH Standardization and Titration of an Unknown Organic Acid Overview: Methods for counting the number of molecules in a sample is a major emphasis of laboratory work. In this experiment we will use the method of titration to count the number of acid molecules in a solution. Measuring mass is a relatively easy procedure to do in the lab (although a balance is expensive). Counting the number of particles requires more effort. Molecular counting can be done by setting an unknown amount of a substance

Beer Lambert Law Lab Purpose: The purpose of this lab is to prove the Beer Lambert Law experimentally. The various solutions used for this experiment are tap water mixed with food colouring‚ Introduction: The Beer Lambert Law shows the relation between absorbance of light of an object‚ the molar absorptivity‚ the concentration of the substance‚ and the distance the light travels. The Beer Lambert Law states that there is a linear relationship between the concentration of a solution and the

According to Charles’ Law‚ temperature and volume increase proportionally‚ as long as chemical amount and pressure remain the same. Research Question: How does the volume of a balloon react to changing temperatures? Hypothesis: If we increase the temperature

Newton’s 2nd Law Lab Introduction: The purpose of this lab was to prove Newton’s 2nd Law; which states accelerate equals force divided by mass (a=F/m). During this lab we were trying to find out the relationship between acceleration‚ force‚ and mass by using a air track‚ glider with picket fence‚ and photogates. Before I did the lab‚ I had already knew that acceleration‚ force‚ and mass were related. I just didn’t know how they were related. When recording the results of this lab we had to record
