  • Implementing Clock Element on Altera DE2-115 Board

    744 Words  | 2 Pages

    This report presents the implementation of a Clock element and the use of the seven segment display on the Altera DE2-115 board. This experimentation with the clock and display are valuable since they are a precursor to future labs to come. In order to make these items work it required the use or Verilog code, which was given for parts 1, 2, and 3. In Part 1, the user was presented with code that enables use of the internal clock on the DE2-115(Appendix A-1). After compiling the user was to find

    solution into a stronger solution through a partially permeable membrane. We hope to achieve this by doing four experiments using distilled water in one test tube and different concentrations of salt water in the other test tubes. Once done, we will measure the change in mass. Prediction I think that the potato that is put in the test tube with water in will gain in mass. I think that the potato put into the salt solution will loose in mass. The higher the concentration of salt the, the more

    correct temperature. The water was put into a beaker. 5ml of starch was put into a test tube. The test tube was placed into the beaker. When the water in the beaker was at the required temperature the stop clock was started. After one minute 1ml of amylase was put into the test tube with the starch using a syringe or pipette. As soon as the amylase and the starch had mixed a sample was taken from the test tube using a pipette and mixed with the droplets of iodine in one of the chambers of the

    As I looked out the window of the restaurant, I could see the sun bouncing off the sparkling water below. Boats and other water craft scatter the water as well as people on water-skis and inner tubes. The picturesque view makes life seem so much better and just looking at the river makes a person calmer. The scene just described is the view from the window of a restaurant called Sophia in Minneapolis, Minnesota, and the corresponding river is the mighty Mississippi. Although Minnesota is the land

    discuss the normal function of the lungs, and then proceed to explain how this is effected by asthma. The causes of the disease and the ways of controlling it will follow. Normal breathing is controlled by the lungs and the chest cavity. Airways are tubes with muscle that contracts and relaxes wrapped around them, and this accounts for the motion of the chest that is associated with breathing. The diaphragm, which is located underneath the rib cage, along with the intercostal muscles, or those in between

    According to an article in Newsweek called The Brave New World of Sex Selection by Thomas Hayden, this is possible. The article states how it is done. To do this, scientists measure DNA in sperm cells and pass the millions of them through a tiny tube in a single file. They then separate the “girl sperm” from the “boy sperm”. They can tell the difference because “girl sperm” has more DNA. The separated sperm cells are then used, one or the other, to impregnate a woman to have a girl or a boy

    calculate rate of reaction, and calculate the effect of the factor by measuring the amount of gas given of during the reaction, and finding out how much gas is given of every 15 seconds. I will collect the gas by bubbling it into a gas collection tube in a water bath. I will use five different concentrations 80%, 70%, 60%, 50%, and 40% acid. I will mix acid with water to get the desired concentration, and for each experiment I will keep the volume of the acid and water combined at 50 ml.

  • An investigation into whether the voltage affects the amount of gas produced during the electrolysis of sodium chloride solution

    1188 Words  | 3 Pages

    voltages 5,6,7,8,9 and10 because for voltages lower than five there was not a lot of gas produced this made it extremely difficult to measure the amount of gas. For voltages over 10 there was too much gas produced and it went out of both sized measuring tubes. I decided to do it for 2 minutes as this figure seemed to be the one where the results were at their best, they were easily measurable unlike the results for one and three minutes.
