• Naval Accidents World Mistakes Major
    398 words
    United States Naval Accidents There have recently been two major accidents involving the US Navy; both involving citizens of foreign countries. The first incident involved the USS Greenville submarine and the second a US Navy Hornet. I have come to believe that that the combination of the two incidents will have a major effect on the performance in future military actions. With the commander of the USS Greenville given blame for the tragic accident and an investigation beginning of the recent ac...
  • Glass Tube Flow Water Rate
    3,768 words
    Hypothesis This investigation starts by investigating the effect of the length of glass tube on the rate of flow of water out of it. The volume per second of the water flowing out of the tube (rate), is determined by the forces acting. The pressure force pushes the fluid through the pipe against the resistance of the viscous force. Therefore I would expect a longer glass tube to create more force opposing the movement of water and therefore produce a slower rate. In this experiment I expect to f...
  • Maxwell Relations 8706 Equation State
    2,120 words
    My topic for the report is Thermodynamics Maxwell Relations, and in this report I will show how to derive the Maxwell Relations, as well as give several examples of how and when they are supposed to used. The change in U depend on the changes in the system entropy, volume and XI's this idea may be abbreviation (1-1) U = U (S, V, XI) In system of constant mass and composition, whose work can be expressed only in terms of its PV properties, there are no X's and U is changed only by reversible heat...
  • Theme Developed Through Motif In Death Of A Salesman
    694 words
    Most people find that a reacurrance of theme in a play or never can be developed through motif. In the play Death of a Salesman, the main theme of the American Dream is developed through a character's motif, they are the constant stealing of Biff, the image of the new stockings and the pattern of the Loman's car. One of the most prevalent problems in the play is Biff's constant stealing. These events occured many times through the play and they eventually led heart ache and pain. As a child, Bi...
  • The Photoelectric Effect Stopping Potential
    1,868 words
    The Photoelectric Effect The purpose of this experiment is to determine h / e (Plank's constant in units of electron volts), the work function F, and the threshold frequency for the photochathode surface provided. Three filters each having a distinct wavelength, were used to carry out this experiment. Utilizing these filters, 435. 8 nm, 546. 0 nm, and 577. 0 nm, data in voltage and current was collected, as potential was selected at random points for each wavelength. This data was then plotted ...
  • Lift Weight Thrust And Drag
    733 words
    One of the first things that is likely to be noticed during a visit to the local airport is the wide variety of airplane styles and designs. No matter what each looks like like they all depend on the the same four factors which are lift, weight, thrust, and drag Lift is the upward force created by the effect of airflow as it passes over and under the wings. It supports the airplane in flight. Weight opposes lift. It is caused by the downward pull of gravity. Thrust is the forward force which pro...
  • Solar Energy An Alternative Energy
    294 words
    Solar Energy: An Alternative Energy Imagine a perfect source of energy. One with which no pollution what-so-ever is associated with. No poisonous gasses or destruction of rain forests. This abundant source of energy comes from the sun. Solar energy is the visible energy produced in the sun as a result of a constant nuclear fusion reaction that is taking place. The amount of energy at the solar constant, which is at outer edge of the earth's atmosphere, is two calories per minute per cm squared. ...
  • Differences Which Separate Pope From Wordsworth
    296 words
    Key Differences Which Separate Pope from Wordsworth In comparing excerpts from Pope's "An Essay on Man" and Wordsworth's "Prospectus", I found many similarities and some key differences. Pope's lean toward the more structured and confined, and Wordsworth's lean towards the informal and original. These differences are what separate the styles of both poets and make Pope "regular" or formal and Wordsworth "irregular" or unique. Both poems are done in iambic pentameter; however, Pope's is rhymed wh...
  • Faraday's Law Iron Rod
    431 words
    PHY 2049 Faraday's Law 1) ABSTRACT: Relative motion between a magnetic field and a conductor are needed to create a voltage within the conductor. For current to flow the conductor must be a complete loop, if not the current will not flow. 2) THEORY: Faraday's Law (V = -N (Df/Dt) ) 3) PROCEDURE: A. A coil is connected to a galvanometer, completing the loop. A magnet is passed through the coil. B. A coil is connected to a galvanometer, completing the loop. Many magnets are passed through the coil...
  • Relationship Between The Current And Voltage
    2,984 words
    Aim: To investigate the relationship between Current and Voltage Scientific Knowledge The current and voltage of an electric circuit, is given by the formula V = IR. This is known as Ohms. Ohms Law is only applicable, when the temperature of the resistor is kept constant. Therefore Ohms law is only applicable to Ohmic conductors. An example of Ohmic conductors are metals and alloys at constant temperatures. Anything that doesnt obey Ohms law, are know as non-Ohmic Conductors. An example of thes...
  • Television Wars Desensitize Us

    Television Wars Desensitise Us Television wars desensitise us. The constant bombardment of brutal fighting on our everyday television sets undoubtedly desensitise us. Statistics show, that about 97% of New Zealand homes have a television set and more than half have more than one set. Considering that our news hours are filled with conflict from countries all around the world, these numbers clearly show that the majority of the New Zealand population is exposed everyday to television wars and vio...

    The Baby Scream BABY SCREAM The constant use of similar events while progressing to the different conclusions of the story demonstrates in "The Babysitter' human's lack of responsibility. The story initiates its narration by the arrival of the babysitter at 7: 40 and continues by the successions of events as the evening progresses. The course of actions by the babysitter and the other characters are all, initially, unfamiliar to the reader but as the evening progresses, the events start to repea...
