determine the value of the acceleration of a free falling object and to describe the range of experimental values. Within the experiment the items used to help provide the conclusion that 2/3 or our values fell within the 9.62m/s^2- 9.78m/s^2 range was a Vernier data-collection interface‚ Logger Pro Application and the apparatus Photogate. The results found within the 30 trial periods were all precise. It was believed that the data would not be exact to the actual acceleration of gravity but would be precise

Theodolite Adjustment The most significant errors affecting the operation of a theodolite are geometrically cancelled by recording angle readings in both direct and inverted positions. However‚ that does not negate the benefits of a well-calibrated instrument. In practice‚ many observations are made on one side only (in topographic mapping‚ for example). Also‚ with a finely-tuned instrument‚ a discrepancy in the readings will help identify other problems (e.g.‚ an unstable tripod‚ observation or

The Effect of Exercise on Blood Pressure Katie Law-Balding June 28‚ 2010 Abstract The purpose of this experiment was to see what effect 30 seconds of physical activity would have on a subject’s blood pressure. In this case‚ physical activity is defined as stair running at a moderate pace for 30 seconds. Standing blood pressure was measured before and after physical activity for comparison purposes. Three trials were completed and initial blood pressure was 94/75 mmHg‚ 125/92 mmHg‚ and 106/92

. Introduction A. Background of the Study One of the more common occurrences in our daily life is sustaining wounds ranging from mild abrasions to deep lacerations. Wounds that are left untreated can result to infections and other complications‚ so proper remediation must be done immediately. For the past several years‚ there has been a lot of advancement in the field of medicine. The discovery of new drugs has played a big role in the improvement of our health care. But due to the prohibitive

When questioning Lector on Mofet‚ Lector states his real name is Benjamin Rosebell (who had the same moth in his mouth) and he was in a relationship with Louis. Lector informed the moth symbolizes change – caliper to a butterfly is beauty. He stated Buffalo Bill as was not made a criminal he became a criminal stemming from serve child development and abuse. He also stated he hated his own identity which gave him the idea that he was transgender (Demme‚ 2001)

HYDROSTATIC FORCE (EXPERIMENT 1) INTRODUCTION The determination of force which are exerted by liquid which are at rest on surface immersed in liquids. From the study by hydrostatic‚ the following principles have been established : a) There are no shear stress present when the fluid is not in motion. b) The pressure exerted by a fluid under hydrostatic conditions. This pressure acts perpendicular to an immersed surface. c) Hydrostatic pressure various linearly‚ increasing with an

Collecting Photosynthetic Rates in Spinach (Spinacia oleracea) Introduction: The purpose of this study was to see which light color would cause the spinach sample to photosynthesize the most within the given time. In order to understand photosynthesis‚ we need to know that chloroplasts absorb light energy from the sun‚ the plant then takes that energy along with water and carbon dioxide and changes it to sugar and oxygen. This happens in order for the plants to grow. But‚ light energy comes in a
