Oscillators & Oscilloscope Morgan Dennis @02514008 Partners: Brittany Smith‚ Michelle Trang‚ James Anderson‚ Madison Shaw OBJECTIVE: We are going to study the features and operation of the oscilloscope. We will use the instrument to measure the frequency and amplitude for various sources. Ultimately‚ the oscilloscope will display the Lissajous figures. APPARATUS: The major apparatus used include; Oscilloscope‚ two audio oscillators‚ battery and connectors. THEORY: The oscilloscope

Introduction Memory is defined as the faculty by which the mind stores and remembers information(Eysenck & keane‚ 2010). Atkinson and Shiffrin (1968) (Cowan‚ Rouder‚ & Stadler‚ 2000)‚ came up with a model of sensory memory which stated not everything we perceive we process. Craik and Tulving (1975) developed an opposing theory in which they proposed the levels of processing theory‚ stating its not the processing but the type of quality of the processing that is performed‚ that determines the retention

Job Safety Analysis or Job Hazard Analysis All employers have duty of care to individuals‚ staff‚ contractors or third parties in the workplace. It is also a legal requirement that organizations should document any health and safety risks that have been identified in the workplace. Equally‚ it is necessary to record the actions taken to reduce those risks What is a Job Safety Analysis or Job Hazard Analysis? One way to increase the knowledge of hazards in the workplace is to conduct

INTERPRETATION OF RESULTS: This experiment circles around with the Newton’s second condition of equilibrium in rotational motion. It describes by net torque acting on a body which is zero. The ability of the body to rotate in a certain direction is varied according on how much torque is applied. To prove that‚ a beam that is subjected to two forces is balanced by adjusting the perpendicular distances. When applied force is weight‚ modification in masses added is also done. Once equilibrium is achieved

EXPERIMENT 5 SEPARATION OF A MIXTURE INTO ITS COMPONENTS BY FRACTIONAL CRYSTALLIZATION Introduction: Fractional crystallization is one of the experimental techniques used to separate or purify mixture. Fractional crystallization makes use of the differences of solubility to separate the components of a mixture. Goals: Applying fractional crystallization to separate a mixture of salicylic acid and copper sulfate pentahydrate into its components. Calculate the percent of salicylic

Effect of enzyme concentration on rate of reaction Research question: is there a relationship between catalase concentration and the rate of reaction? Hypotheses: if the enzyme concentration is increased then the rate of reaction will increase. If the enzyme concentration is decreased then the rate of reaction will decrease. Controlled: temperature Independent: % catalyze concentration ( Dependent: rate of reaction (mm/s) Materials: Mortar and pestle Graduated cylinder Distilled

walked past a penny on the ground or carelessly dropped it on the floor and not picked it up‚ thinking that a penny is not worth your time. The Canadian mint produces nearly one billion pennies a year and sets them off for circulation where most of them will spend their time on the streets or collected in jars. The Royal Canadian Mint says it costs only 0.7 cents to make a penny but if you factor in other costs such as shipping the pennies to banks then it could add up to 4 cents per penny. Surely we

Penny Synthesis Essay To “… not ban pennies‚ but merely discourage their use by establishing a system…” It is because I agree with Mark Lewis of Forbes.com‚ that I affirm abolishing the penny‚ yet with some restrictions. In 2001 a United States Representative by the name of Jim Kolbe introduced a proposition to eliminate the penny (United States’ lowest denomination coin). To deeply reason as to why an individual might support this proposition‚ we must look at three different points of analysis

Abolish the Penny Between 2001 and 2006‚ there has been an increase of .6 cents for the reproduction of the penny. This increase displays economic problems that may lead to fatal ones. The penny is composed of 2% copper and 98% zinc. These elements are exponentially in demand causing the price of these materials to skyrocket. Many Americans think the penny is putting our country in jeopardy with financial losses. This meaningless coin is losing money for the mint‚ and should be abolished.
