Mountain Dew Water Vapor
1,257 wordsWhy are we as Americans so afraid to change? even if it is a change for the better? the world has been using oil coal and other petroleum products to power just about everything that moves for the last 150 years. yet most cars in the united states only get 10 - 20 miles a gallon and even the "good" ones can get only a petty 20 - 50 miles a gallon. so why do we put up with the inefficiency when there are far better alternatives out there? Such as hydrogen, which was discovered hundreds of years a...

Cross Sectional R R
864 wordsDetermination of r for a Metallic Conductor To determine the resistivity (r) of a given sample of wire Physical factors that affect the resistance of a conductor are length, cross sectional area and a constant that depends upon the material called the resistivity. The resistance per unit length is the same all along a uniform wire so if the resistance of different lengths of a wire is found out, the resistivity can be calculated. Resistance of a material, R = Voltage / Current Resistance of a co...

Burning Sensation Nine Years
1,455 wordsCan I have a regular king size Demurer please? Thats what I use to say after finishing a pack of cigarettes before the day was even finished. It all started nine years ago my first day of grade nine. I wanted to be cool so the cool kids would like me. I managed to get my hands on a cigarette and a lighter; I sparked it and took a puff. I felt a burning sensation down my throat as if I have been trapped in a burning house full of smoke. I coughed and coughed clearing my throat trying to spit out ...

8 And 10 Ohms 127 5 135 Voltage
462 wordsPurpose: The purpose of this lab is to see if and how Ohms Law applies in a circuit that doesnt have a resistor. Theory: Equations Resistance = Voltage/Current R = V/I Voltage = Current Resistance V = I R Current = Voltage/Resistance I = V/R Hypothesis: I hypothesize that the resistance will be between 8 and 10 ohms. Procedures: Assemble a circuit with a multimeter, to measure the current, a voltmeter, to measure the volts, and a resistor that will provide the resistance. Next, a hand-held gener...

Death Penalty Evil Deed
1,030 wordsThe average homicide rate in the 13 states without the death penalty is lower than the average homicide rate in the 37 states where it is legal. Between 1972 and 1990, the homicide rate in Michigan which has no death penalty, was generally as low or lower than the neighboring state of Indiana, which restored the death penalty in 1973. The U. S. Bowers- Pierce study analyzing executions between 1907 and 1963 concluded, that an average of two additional homicides were committed in the month after ...

Gas Chromatography Data Collection
939 wordsGas Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to be a ...

Reading Across The Curriculum Stanley Milgram
974 wordsConformity and Obedience The desire to be accepted and belong to a group is an undeniable human need. But how does this need affect an individual? Social psychologists have conducted numerous experiments and concluded that, through various forms of social influence, groups can change their members thoughts, feelings, and behavior. In her essay Group Minds, Doris Lessing discusses our paradoxical ability to call ourselves individuals and our inability to realize that groups define and influence u...

Firing Squad Capital Punishment
640 wordsThe Death Penalty has been around since and before the Americas were found. Even though it has been in affect for hundreds of years, I do not feel it is at all right. The methods are cruel and in some cases, very painful for the inmate. most people think the death penalty is a good way of justice in the United States, and it is said to be a humane way of execution, but from what I have found, it is far from humane. Since 1976, 549 people have have been executed by lethal injection, 149 by electr...

Circuit Under Test 555 Timer Ic Logic
466 wordsLOGIC PROBE SUMMARY Logic Probe is one of the basic troubleshooting tools for common electronic logic circuits (TTL circuits). Almost all video game circuit boards are built using TTL chips. These chips will occasionally fail and the Logic Probe is a tool that affords us a look into what may be failing, and it s a very handy measuring device used to determine output logic levels. The 555 timer IC is used in this circuit. The 555 timer IC uses power supply voltage from about 5 volts up to 18 volt...

Gamma Rays Weak Points
671 wordsGamma Rays are Waves on the electromagnetic Spectrum that have a Wavelength of 10 or Higher and 11 down. Gamma Rays are produced in labs through the process of nuclear collision and also through the artificial Radioactivity that accompanies these interactions. The high energy nuclei needed for the collisions are accelerated by such devices such as the Cyclotron and synchrotron. There are also many uses for Gamma rays in Medicine. Gamma Rays are used in medicine to kill and treat certain types of...

Inversely Proportional Cross Sectional
1,082 wordsAim I am going to be studying the resistance of wire. The purpose of this investigation is to see how length and thickness of wire affect the dependent variable, resistance. Prediction I predict that, as the length of the wire doubles, the resistance will also double, but as the cross-sectional area of the wire doubles, the resistance halves. This means that the length will affect the resistance more than the thickness will. Hypothesis Resistance is caused by electrons bumping into ions. If the ...
