Mcgraw Hill Book Hill Book Company
1,129 words... t additional return he would require to compensate for a specified increase in risk. So, the most desirable combination of risky assets depends on the decision -maker's attitude towards risk. If we know the extent of his or her risk-aversion that is, how large a premium he / she requires for a given increase in risk, we could specify the best portfolio. The portfolio combination model, although having limited operational usefulness for many investment projects, provides the infrastructure of...

Chemical Reaction Kinetic Energy
633 wordsThe rate of a chemical reaction is the derivative of the extent of the reaction with respect to time, to measure the effect of concentration upon the rate of the reaction of peroxydisulfate ion with iodine ion; to determine the order of the reaction with respect to the reactant concentrations; and to obtain the rate law for the chemical reaction. Four reaction solutions are prepare as: 1 - Dilute 5 mL of 0. 2 M KI solution with 10 mL of distilled water in a test tube, add 3 drops of starch solut...

Sodium Hydroxide Universal Indicator
854 wordsExperiments to Determine the Effect of Acids & Bases on Different Indicators and the pH of Common Cleaning Agents The aim of the first set of experiments is to find out and record the colour changes that are observed after a certain indicator is mixed with acids and bases to form a colour reaction. Once the selected indicator has been mixed with a acid that is both weak and strong and a base / alkali that is both weak and strong we are to record the colour and choose another indicator. The purpo...

Goldenrod As Solidago Classified As Solidago Species
389 wordsGoldenrod is common name for certain related plants of the composite family. The Canada goldenrod is really Solidago canadensis. They are typical autumn flowers of the United States that grow in a great variety of habitats: woods, meadows, hills, and rocky ground. For many years goldenrod was considered a major cause of hay fever, but experiments with goldenrod pollen have indicated that it is virtually harmless. It is so heavy that certain types of bugs actually have to lift it out. It is the s...

William Thomson (Lord Kelvin), referring to levitation as the problem of 'Mohamed's coffin, ' had this to say: 'It will orally be impossible ever to observe this phenomenon, on account of the difficulty of getting a magnet strong enough, and a diamagnetic substance sufficiently light, as the [magnetic] forces are excessively feeble. ' Fields strong enough to lift...

Rate Of Reaction Hydrochloric Acid
1,681 wordsInvestigating The Rate Of Reaction Between Sodium Investigating The Rate Of Reaction Between Sodium Thiosulphate And Hydrochloric Acid Investigating the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid Diagram Aim: We did 4 experiments to find out how the rate of reaction changes with differing concentrations of Sodium Thiosulphate, Hydrochloric Acid and water. As an inert and stable liquid, water was used to alter concentration of Sodium Thiosulphate without changing the end a...

Air Resistance Straight Line
1,374 wordsPlanning The experiment is to determine the horizontal motion of a projectile when launched from a ski slope´ at different speeds. It is thought that the rate at which the ball bearing is released from the slope will affect how far it travels in a horizontal direction. The height up the slope that the ball is released will be proportional to the distance that it travels. Therefore, if the height from which it is released is doubled it will travel twice as far. When the experiment is conduc...
