Practical 3 ABSORPTION SPECTRA AND THE BEER-LAMBERT LAW The purpose of this practical was to measure the amount of a chemical substance present in a sample. Primarily‚ the aim of Experiment 1 was to measure the absorption spectrum of a particular coloured substance (in this case Bromophenol Blue and Methyl Orange) at varying wavelengths of light. For Experiment 2‚ the process of the experiment focuses on the substance and records its absorption levels at different concentrations. The absorption levels

between ABC Costing and the Time Driven ABC Costing Activity Based Costing (ABC)‚ is a method used to gather an estimation of the cost of a product or service. It was proposed by Robert S. Kaplan and W. Bruns. It helps to assign costs to products and services‚ of an activity along with the resources‚ based on the consumption that takes place by each product or service. The model helps companies in deciding that which products are not rightly priced and which products are actually costing more or are

All the possible results for the weight of the T-bone steak would be positive numbers making the variable weight (w) > greater than 0. c) The number of free throw attempts before the first shot is made is a discrete random variable because

Activity-Based Costing System A presentation by Ahmad Tariq Bhatti FCMA‚ FPA‚ MA (Economics)‚ BSc Dubai‚ United Arab Emirates Activity-Based Costing Activity-Based Costing System 2 The Concept Activity-Based Costing In contrast to traditional/absorption costing system‚ ABC system first accumulates overheads costs for each organizational activity‚ and then assigns the costs of the activities to the products‚ services‚ or customers (cost objects) causing that activity.

through by measuring the changes in the selected variables. The Variables that we selected were stem length‚ root length‚ the amount of leaves that grew on a plant and the overall size of the plant measured in height. For this experiment‚ we had three test groups‚ the first two groups had five seeds and the third group has 10 seeds. The reason for that is because we introduce the third group to interspecific competition. We wanted to find out if variables such as competition will have an effect on

allocation of cost to each product since this is critically important not only for stock valuation and income determination but also increasingly for assessment of excise duty‚ transfer pricing etc‚ and also for divisional profitability etc. This study concentrates to explore the area not so much conceptually‚ but more as a practical guide to illustrate some of the methods adopted in practice by the manufactures’. The methods fall under two broad categories a) Market value basis and b) Physical
