Resonance 1 Williams Lab 1: Tube Staci Williams Kevin Schesing‚ Nicole Harty‚ Caitlin Kubota Section 015 2 Performed February 2‚ 2010 Due February 13‚ 2010 3 Theory: 2.1 Air As A Spring Williams Gas is a springy material‚ and when placed in a cylinder with pistons on each side it can be compressed as pistons push in‚ raising the pressure inside. There will be a net force from the pressure to push the piston back out. Since gas has mass it can support oscillations and waves. 2.2 Traveling Sound Waves

from the center of the earth. If the object were falling in a vacuum‚ this would be the only force acting on the object. But in the atmosphere‚ the motion of a falling object is opposed by the air resistance or drag. The drag equation tells us that drag is equal to a coefficient times one half the air density (R) times the velocity (V) squared times a reference area on which the drag coefficient is based. The motion of a falling object can be described by Newton ’s second law of motion‚

Column Chromatography of Plant Pigments Jaybee Balilea‚ Sharmaine Baysic‚ Maria Anjelette Patricia Belen 3Bio-7‚ Department of Biological Sciences‚ University of Santo Tomas‚ Manila‚ Philippines Abstract Column Chromatography is a form of solid-liquid adsorption chromatography and depends on the essential principles as does in thin layer chromatography. It was used in this experiment in separating and analyzing the different components of Capsicum frutescens (siling labuyo) with the use

Column Chromatography of Plant Pigments Paul Ibarbia‚ Gene Paolo Jasmin‚ Gianpaolo Jimenez and Lorenzo Labicane* Department of Biology‚ University of Santo Tomas‚ Manila‚ Philippines Abstract Column chromatography of plant pigments is the separation of plant pigments extracted from Capsicum frutescens (siling labuyo). No slurry is prepared of the eluent; eluent with the stationary phase is set and then carefully poured into the column. The eluent are the solvents which are responsible for the

Trajan’s Column Romans had great achievements in the field of art. Especially in the sculptures and architectures. The emperors of Rome were filled with ambitions. They wanted their name be written in the history and be remembered by their posterity. So they warred around and build all types of monument to celebrate their military victories. One type of monument favored by the Romans --- suggestive not only the power but also of male virility--- is the ceremonial column. “Trajan’s Column‚ perhaps

INTRODUCTION: Magnetic Resonance Imaging(MRI) is a non invasive medical imaging method widely used in hospitals and in research. In year 1946 Felix Bloch of Standard /university and Edward Purcell of Harvard University made the first succesful nuclear magnetic resonance experiment to study chemical compounds‚ they were awarded the Nobel Prize for physics in 1952. In early 1980 ’s the first human magnetic resonance imaging( MRI) scanners became available‚ producing images of the inside of the

Experiment 7: Velocity of Sound Jaybee J. Balilea‚ Sharmaine O. Baysic‚ Maria Anjelette Patricia C. Belen‚ Dianne Grace D. Bolloso Department of Biological Sciences College of Science‚ University of Santo Tomas Espana‚ Manila Abstract Sound is a mechanical wave that is an oscillation of pressure transmitted through a solid‚ liquid‚ or gas‚ composed of frequencies within the range of hearing and of a level sufficiently strong to be heard. It is produced when something vibrates causing

Distillation Column In the the Chemical Enginneering Lab at CSULB there is a total reflux eight-stage glass binary distillation column at atmospheric pressure. The components that need to be separated are 1-propanol and 2-propanol. These two compounds are isomers with fairly close boiling points. They are separated based on their physical propertis. With the

Ferrocene and Acetylferrocene will be separated using column chromatography. Column chromatography is a separation technique that is used among many disciplines including biology‚ biochemistry‚ microbiology and medicine. Many common antibiotics are purified by column chromatography.1 Column chromatography allows us to separate and collect individual compounds. In this experiment‚ lumen will be the stationary phase‚ and the more polar substance will be retained on the stationary phase longer
