Experiment 1 Introduction to basic lab equipment and components Introduction: To use an electronics lab‚ it is necessary to become familiar with some typical equipments and components‚ to reduce the accident and damaging the equipments. So the experiment will be accomplished with the right result and everything still in one peace. Objective: • To be familiar and understandings the operation of the basic components and equipments in electronics lab. • To know the color code of the

ACKNOWLEDGEMENTS The purpose of this study was to determine how teenagers spend their leisure time in El Dorado West Secondary School. This process was carried out using a questionnaire with fifteen questions. It would not have been possible and enjoyable without the help of my teacher‚ Mr. Sooknanan. I want to him for his guidance and Ms. Forbes also as well as the Almighty God for the inspiration to do this project. INTRODUCTION El Dorado West Secondary School is a high school located in

process of distillation. Distillation is the separation of volatile substances mixed with nonvolatile substances by boiling the mixture to alter the phase of the volatile substance. The researchers used the simple distillation set up to conduct the experiment. 25 ml of The Bar Vodka was used and 7 ml of distillate was collected before a temperature of 95 degrees Celsius was reached. Collected distillate was then subjected to a flammability test to confirm ethanol content. The percent ethanol was computed

PHY 114 Faraday’s Law of Induction Stephanie Scott Section: 10849 Group #3 Bochao Li 3/31/15 Abstract: The objective of the Faraday’s Law of Induction lab was to verify Faraday’s law of induction by measuring the emf generated in a small coil and comparing it with the calculated value. Secondly the goal was to investigate the relationship between the emf and the frequency of the driving signal. The magnetic field was found to be uniform throughout. For the frequency of 40 Hz‚ the average

Alixandria Zeidel Physics 131 – section LZ Hasbrouck 208 10/01/14 Forces and Newton’s 2nd law Abstract The purpose of this lab was to learn about how force influences acceleration. A hanging mass is tied to a frictionless glider and the mass is dropped. While the glider is being pulled by the mass it is possible to measure to tension force on the rope between the two objects. A motion sensor graphs the movement of the system and from the slope it is possible to calculate the acceleration of both

Austin Vandermey GS-1140 April 4th‚ 2015 Experiment We as a society have one big problem on our hands. This problem is sleep deprivation because there are not enough hours in the day to get stuff done. Between work‚ school‚ family‚ and leisure it seems like we do not have enough time to get are daily tasks done let alone have time for sleep. It is recommended by the U.S Department of Health that people need a solid eight hours of sleep to maintain good health. I don’t know about you
