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

Kidney Disease- The kidney is a very vital organ to a human’s healthy existence. The pair of bean shaped organs are responsible for many important functions‚ they aid in the Urinary system as was as the Endocrine system. Their main functions are to filter wastes from the blood and secrete hormones. Due to the fact that the kidneys are responsible for maintaining regulation of the body ’s salt‚ potassium and acid content‚ they also play an important role in maintaining a proper homeostasis. According

benefits of kidney transplants. Kidney transplantation is the organ transplant of a kidney into a patient with end-stage renal disease. In the Early 1900’s European doctors attempted to save patients dying of renal failure by transplanting kidneys from various animals‚ including monkeys‚ pigs and goats. None of the recipients lived for more than a few days. And In the late 1940s and early 1950s‚ a team of doctors at Boston’s Peter Bent Brigham Hospital carried out a series of human kidney grafts
