    Mass communication, by definition, is the process in which professional communication using technological devises share messages over great distances to influence large audiences. The technology of modern mass communication results from the confluence of many types of inventions and discoveries, some of which (the printing press, for instance) actually preceded the Industrial Revolution. Technological ingenuity of the 19 th and 20 th centuries has developed the newer means of mass communication,...

    1,051 words
    Percent Composition Of Water In Copper SUlfate Pentahydrate (Lab Report Version) Abstract The percentage of water in Copper Sulfate Pentahydrate was found. Copper Sulfate was heated in a crucible to evaporate the water. The mass was weighed to find the difference before and after heating. By comparing these masses, the percentage of water was found. The percentage of water was found to be 34%. Theory Copper Sulfate Pentahydrate or Cu SO + 5 H O is a solid compound. To find the percentage of wat...
  • Momentum Elastic Collision
    654 words
    Abstract Measurements of velocity and mass of two objects colliding, support the conservation of linear momentum. The dynamics of different masses distinguish velocity values experimentally. Video recordings of two colliding masses can be manipulated to extract frames displaying distance verses time. Computer software enables us to derive the velocity. Different masses were tested to determine an increase, decrease, or equal effect. From this data, we ultimately derive the momentum of each cart ...
  • Osmosis In Potato Chips
    1,639 words
    ... After 30 minutes I drained out the solutions in the sink and placed all the chips on the paper towel in the order I had put them in the test tubes as to not confuse myself as to which chip came from which solution. 10. I dried each chip with the paper towel and then placed each one on the scales so that I could weigh them. 11. Each potato was measured accurately on the electronic scales and then the weights were recorded. 12. As I had time after doing the first set of results I redid the ex...
  • Reasons To Vote Candidates Mass Media
    509 words
    This activity is rational because candidates must gain and maintain public support. The extensive campaign that most candidates go through requires large sums of money. This money is used to become visible to the mass by the media. The media is responsible for linking the elites with the mass. This is why the elites use the media so much. The media portrays the candidates in a light that will get the most ratings. Candidates spend more money to help put a positive spin or a higher approval rati...
  • Finding Mass Using The Inertial Balance
    663 words
    Finding Mass Using the Inertial Balance Theory: Physics can be referred to as the study of various properties of matter and energy. Matter can best be described by looking at the mass of an object. Mass is the amount of material that is in an object. Mass can be found by using a spring scale, a balance scale, or an inertial balance. Inertia is the resistance by mass to any change in its state of motion. Scientific Law states that mass and inertial forces are directly proportional. The purpose o...

    Puerto Rican Cultural and Religion I am a member of the Puerto Rican American Families research team. Myself grew up in a Puerto Rican American, or 'New Yorican', family. The assignment is a field study. The study is on an observation of the religious community. We visited a Roman Catholic church in Buffalo on the west side, which is a predominantly Hispanic area of the city. I myself am also a Roman Catholic. This is a slightly erred site, because I believe that most Puerto Ricans migrated to ...
  • Gum Percentage Of Mass
    681 words
    In this experiment the independent variable was the amount of mass lost by the gum, the dependant variable was the time the gum was chewed. The controls were how much time was spent chewing, and how each was weighed. In the experiment first each member of the group took a different piece of gum and wrote down what kind it was. Then they massed the gum and wrapper. After that they began to chew for two minutes. During this time no one was supposed to speak or deter from their chewing. At the end...
  • Mass Spectrometer Water Ions Charged
    533 words
    Mass Spectrometer A mass spectrometer produces charged particles (ions) from the chemical substances that are to be analyzed. The mass spectrometer then uses electric and magnetic fields to measure the mass (weight) of the charged particles. There are many different kinds of mass spectrometers, but all use magnetic and / or electric fields to exert forces on the charged particles produced from the chemicals to be analyzed. A basic mass spectrometer consists of three parts: 1. A source in which ...

  • Mass Energy Equivalence Nucleus Nuclear Graph
    741 words
    Mass-energy equivalence deals with the release of large amounts of energy from nuclear reactions. An example of a nuclear reactor would be U-238. In the name of relativity, energy and mass is significantly the same thing, hence, making the mass of a U-238 nucleus equivalent to the sum of masses of the 238 nucleons that makes the nucleus up. With mass-energy equivalence, work is no longer equal to the product of force and distance. An example of mass-energy equivalence would be going into the U-2...
  • Moment Of Inertia Mass Rotational Axis
    335 words
    Moment of inertia is the name given to rotational inertia, the rotational analog of mass for linear motion. It appears in the relationships for the dynamics of rotational motion. Moment of inertia is defined with respect to a specific rotation axis. The moment of inertia of a point mass with respect to an axis is defined as the product of the mass times the distance from the axis squared. The moment of inertia of any extended object is built up from that basic definition. The general form of th...

  • Electronic Scale Mass Balance Precise
    496 words
    By using three devices, the platform balance, electronic scale, and the inertia balance it is possible to defy the relationship between mass and weight. The mass of an object relates to the amount of matter there is present. On the other hand, gravity is referred to as the pull or force of an object to the Earth. The platform balance and electronic scale are balances that require gravity to "pull" or have a force on the objects being measured to obtain its mass. The mass measuring device that wo...

    Chapter Three Summary: Atoms and atom's structure Ancient Greek Philosophers suggested that matter was composed of individual particles, which was proved by the theory of John Dalton. The main provisions of his theory are: 1. All matter is composed of tiny, indivisible particles called atoms. 2. All atoms of a particular element are identical but the atoms of one element differ from the atoms of other element. 3. Atoms of different elements combine with each other in certain whole number propor...

  • Biology Of Cancer Cells

    Cells inside of our body are under strict genetic control. If the genes controlling our cells become mutated, the cells can become disorganized by losing their function and dividing abnormally at less restraint than their neighboring normal cells. This activity causes the cells to fail to fully mature. Within our cells, we have regulatory proteins that perform such functions as correcting damaged genes. Other proteins indicate to a cell that division must cease so it can mature. A mutation of th...
