Experiment 2: Laboratory Techniques and Measurements Course Number: CHE 111 Abstract: This experiment introduced the student to lab techniques and measurements. It started with measuring length. An example of this would be the length of a nickel‚ which is 2cm. The next part of the experiment was measuring temperature. I found that water boils around 95ºC at 6600ft. Ice also has a significant effect on the temperature of water from the tap. Ice dropped the temperature about 15ºC. Volumetric

Through the use of numerical measure‚ the Motion Picture Industry can be analyzed more specifically. Descriptive statistics can assist analyst to measure data in terms of location‚ variability‚ association between two variables‚ as well as using data for exploratory analysis and the shape‚ relative location‚ and the identification of outliers. The data presented offers a look at four data sets including opening gross income‚ total gross income‚ number of theaters‚ and weeks in the top 60 movies

HSC PHYSICS 2011 PENDULUM MOTION BY NATHAN LOCKE Image taken from http://www.practicalphysics.org/go/Experiment_480.html Pendulum Motion Aim: To determine the rate of acceleration due to gravity by using a pendulum. Background Information: Equation One: T=2πlg Where T = the period of the pendulum (s). This is the time taken for the pendulum to return to its starting position. l = length of the pendulum g = the rate of acceleration due to gravity (ms-2) * In order to find the acceleration

material that is outdated-these options tend to not grasp the attention of your employees‚ especially those of a younger generation. More time will be spent mocking the ‘out-dated’ attire then learning from the presentation. Be sure to include the Human Resources department to assist with training and selection of material‚ their roll should included much of the training involved in order to present materials from a legal and employee centered focus. Try to incorporate active learning-this will ignite

The milgram experiment. The three people involved were: the one running the experiment‚ the subject of the experiment a volunteer‚ and a person pretending to be a volunteer. These three persons fill three distinct roles: the Experimenter an authoritative role‚ the Teacher a role intended to obey the orders of the Experimenter‚ and the Learner the recipient of stimulus from the Teacher. The subject and the actor both drew slips of paper to determine their roles‚ but unknown to the subject‚ both slips

Uniform Circular Motion PES 115 Report Objective The purpose of this experiment is to determine the relationships between radiuses‚ mass‚ velocity and centripetal force of a spinning body. We used logger pro to accurately measure the orbital period of the spinning mass and used these measurements to determine the interrelated interactions of the specified properties and viewed the results graphically. Data and Calculations The black markings on the string are about 10 cm apart in length‚ measured

Experiment 3.1 Newton’s Second Law of Motion Aim: To investigate the relationship between net force‚ mass and acceleration Hypothesis: Since Newton’s second law of motion states that the acceleration of an object is directly proportional to the total force acting upon that object‚ we can assume that the more mass being pulled down on the cart the greater the acceleration of it will be and therefore the greater its net force will be. Apparatus: Wheeled carts Pulleys Balance

Interpretation of Results The objective of the experiment‚ entitled Newton’s Second Law of Motion‚ is to verify the direct proportionality of acceleration and net force if the mass of the body is constant and to verify the inverse proportionality of acceleration and mass if the net force is constant. It is now clearly explained and proven that Newton’s second law of motion is true. By experiments‚ the law is proved. All data produced results parallel to what Newton states. We can say that the
