Physics Waves Lab SL Introduction: This lab will investigate the properties of mechanical waves such as a longitudinal wave‚ focusing on the question: Does a change in the frequency of a wave result in a significant and convincing change in the speed of the wave? Hypothesis: Changing the frequency of the wave will not result in a change in speed because the wavelength will change proportionally as in theory. Student Designed Investigation Procedure/ Planning Procedure: 1. Three

offset each other and hence‚ the irrelevance of dividends‚ is not a practical proposition; it is of merely theoretical relevance. The validity of MM approach is open to question on two counts: 1. Imperfection of Capital market 2. Resolution of uncertainty Market Imperfection MM assume that capital markets are perfect. This implies that there are no Taxes; flotation costs do not exist and there is absence of transaction costs. These assumptions are untenable in real world situation. Tax Effect

Determining the equilibrium constant from pH values of changing concentrations of ethanoic acid Design Research question: How will altering the concentrations of ethanoic acid affect the pH value‚ and‚ in-turn‚ the equilibrium constant? Background information: When weak acids react‚ the reaction typically does not go to completion. Rather‚ the system goes to an intermediate state in which the rates of the forward and reverse reactions are equal. Such a system is said to be in chemical equilibrium

The Power Distance - Power distance describes the degree of equality between different people within a particular society or group. Also described Hofstede‚ as: “power distance is the extent to which people expect and are willing to accept that power is distributed unequally. Inequality of power is a basic fact of life. It cannot be 100% eliminated. It is impossible to have no power distance‚ because this means that everyone is exactly equal (skills‚ actions‚ genetics etc) unless you are on about

variable categories make up the first part of the Behavioral Theory Model. Concepts The second part of the model is made up of relational concepts. There are 4 major concepts in Cyert and March’s theory: (1) quasi resolution of conflict‚ (2) uncertainty avoidance‚ (3) problemistic search‚ and (4) organizational learning. These ideas are the fundamentals to understanding decision-making processes in contemporary‚ large-scale business organizations. Quasi Resolution of Conflict. The quasi resolution
