Ohm’s Law Lab Report Number Three Quyama T. Wheeler @02669651 Partner: Munah Kaye Amber Frazier Objective: To demonstrate Ohm’s law and to determine the resistance of a given resistor. Theory: Ohm’s law is the assertion that the current through a device is always directly proportional to the potential difference applied to the device. Electric current is the moving of charges from a higher potential to a lower potential. Wires of different material (a copper wire versus a silver wire‚ for

mass of the beans Dependent variable: the different types of beans Control: The beans Purpose: The purpose of the lab is to find equal measurement of each type of bean. After you find the mass of each bean you need to find the relative mass of each bean. The navy bean will have the smallest relative mass. You will need to wear safety goggles and a lab apron and wash hands after the lab is finished. If you drop any beans pick them up immediately to prevent anyone from slipping. Materials Safety goggles

the 70’s 80’s and 90’s Computer technology took a great leap in development during the 70’s when schools‚ businesses‚ and universities began to use computers. The 70’s would have to be the beginning of the technology of computers‚ as we know it today. The personal computer became big in the 80’s. Now computers are being updated daily‚ if not hourly. During the 70’s computers and computer use began to become known by everyone. This period was a time for development and improvement. The 70’s was where

Lab 19A Answers: 1) If we increase the molarity of NaOH from 0.1M to 0.2M‚ it will actually take less number of drops in order to change the color of the solution. This is because the more concentrated a substance is‚ less of the substance is needed to cause an equilibrium shift. 2) When you add 6.0M NaOH into the iron (III) thiocyanate ion equilibrium system‚ the concentration of Fe3+ ion decreases. This causes the equilibrium system to shift to the left (reactant) side. This is why the solution

AP BIOLOGY Lab 5 Cellular Respiration Objective: To calculate the rate of CR from the data. To then relate gas production to respiration rate. Then test the rate of CR in germinating versus non-germinating seeds in a controlled experiment and then test the effect of temperature on the rate of CR in the germinating versus non-germinated seeds in a controlled experiment. Analysis: 1. The CR is higher in the germinating peas in the cold water rather than in the beads or non-germinating peas

Introduction In early 2000‚ Pawan Bhatia (Bhatia)‚ the CEO of Domino’s Pizza India (Domino’s) was a man in a hurry. Ever since Bhatia took over as the CEO of Domino’s in November 1999‚ he had been frantically reworking the pizza chain’s India strategy. Bhatia was planning to open 150 new outlets by the end of 2002 covering 23 cities‚1 including Bhubaneshwar (Orissa) and Jamshedpur (Bihar). In late 1999‚ Indocean Chase‚ the private equity fund bought a 25% stake in Domino’s operations in India from
