04/04/2012 Simple Harmonic Motion Lab Introduction: In this two part lab we sought out to demonstrate simple harmonic motion by observing the behavior of a spring. For the first part we needed to observe the motion or oscillation of a spring in order to find k‚ the spring constant; which is commonly described as how stiff the spring is. Using the equation Fs=-kx or‚ Fs=mg=kx; where Fs is the force of the spring‚ mg represents mass times gravity‚ and kx is the spring constant times the distance‚ we

School Uniforms Should Students in Public Schools Wear Uniforms? Abstract One of the most controversial issues in public school is the school uniforms. In 1996‚ the issue of school uniforms was bought to the forefront in President Clinton State of the Union address. People argue that uniforms can make schools safer and improve attendance and increase student’s achievement. People opposing school uniforms argue that it has not been proven to work with discipline‚ attendance or the student’s

reaction where the concentration of all the reactants and all the products remain constant over time. Equilibrium as used in chemical systems means that all the chemical forces in a reaction are in balance and that all physical properties of the system (color‚ density and concentration) of all chemicals species involved remains constant. The equilibrium state can be characterized by quantitatively defining its equilibrium constant‚ Keq. In this experiment the Keq for the reaction between iron (lll) ions

Leap Motion Many of us are aware of the Leap Motion with is a small‚ $70 gesture control system that simply plugs into any computer and‚ apparently‚ just works. The most important thing is that‚ if you’re familiar with the touch modality the interface is entirely intuitive (Christopher‚ 2012). It’s touch‚ except it happens in the space in front of the screen‚ so we don’t have to cover our window into our tech with all those unsightly smudges. This new technology unlike a touchscreen interface

No School Uniforms Nicole Ferrin Comm/215 October 3‚ 2011 Michele Watson No School Uniforms When shopping for school clothes‚ many parents have the constant battle with their child of how well their clothes should match other children. In today’s society children are choosing to fit in by what they wear‚ rather than who they are. Schools choose to have uniforms so that parents can cut cost down for school clothes‚ and children can stop worrying about which designer label they have to have

In hopes of acquiring deserved freedom‚ slaves had the right to kill their masters. But while justified‚ violence was futile‚ leading to execution rather than freedom. Constant victims of injustice‚ slaves were dehumanized and dominated by their master. They were unable to conduct their own actions without the permission‚ incapable of traveling without slave passes‚ and often separated from their family. Slaves were treated as livestock and traded at their master’s will. Masters regarded their slaves

school-wide uniform policy. That fall‚ Will Rogers became the first school in Long Beach County to have a mandatory uniform policy. Other schools in the district soon followed drawing national attention‚ including a personal visit from then President Clinton. Recent memories of school shootings around the nation caused President Clinton to urge other school districts to move to uniforms in his 1996 State of the Union Address. This started a seemingly endless debate over school uniforms in public schools
