Accounting Assignment Students Name Institution Question 1 Part A A stakeholder defines any party that is actually concerned or that has some interests in a certain organization. For instance, these particular parties are directly affected by any actions that a firm takes. Company directors, owners of the entity, commonly known as the shareholders, creditors, the community at large, various unions, existing governance and the organization employees are good examples of stakeholders

conventional two level voltage converters. The advantages of multilevel inverter are higher power quality, lower switching losses, low electromagnetic interference and higher voltage capability. The voltage source inverter gives an output voltage or a current with levels either 0 or ±V_dc. They are known as two level inverter. To

The fact that Costco has one of the most efficient market supply chains in the world whereby it facilitates the movement of merchandise from the manufacturer to store shelves with the least amount of physical effort and labor is another reason that makes Costco so successful. As of 2016 Costco inventory turnover ratio sits at 12.94. Inventory turnover ratio for 2016: Sales / inventory; Costco Net sales for 2016 was $116,073,000 and inventory for 2016 was $8,969,000 which comes out $116,073,000 /

Have you ever heard about how electricity are distribute into the electrical system? There have to be circuits that are programmable by a computer in order to make the circuit to perform the right task. For example there are programmable circuits that allow traffic light to change color. Each color is programed for a certain time to change color. For example a red light might change to green after couple of minutes. An electrical machine without circuits will not work because there is nothing that

As large interest rate differentials in favor of EMEs are expected to persist, capital inflows and possibly long term investments ensue (Lavigne et al. 2014, 25; Lim et al. 2014, 8). All of these capital inflows into EMEs due to increased demand and appetite for risk would serve to put upward pressure on asset prices and can potentially lead to financial bubbles and speculative investment as a result of the increased liquidity and risk seeking. Along with effects on capital flows, QE can also have

Experiment 4: Conductivity of electrolyte solutions (Dated: October 29, 2009) I. INTRODUCTION Pure water does not conduct electricity, but any solvated ionic species would contribute to conduction of electricity. An ionically conducting solution is called an electrolyte solution and the compound, which produces the ions as it dissolves, is called an electrolyte. A strong electrolyte is a compound that will completely dissociate into ions in water. Correspondingly, a weak electrolyte dissolves

used for current limiters, this experiment will measure the resistivity of the resistor in ohms. In order to accurately measure the resistance provided by the different substances we will be using a device called a digital multimeter. A digital multimeter is a device used to calculate volt, amps, and ohms.  If the molecular length increases, then the resistivity of the resistor should increase if resistivity is a function of molecular length.  Due to the fact that resistivity affects current applied

In the first couple of words it says “An electric current is a flow of electric charge”. In the first sentence it already gets in to talking about electric currents and how they flow through an electric charge. In the first sentence in Energy Story it talks about how “Electricity figures everywhere in our lives”. Both the articles get right in about talking

This one had red wires which transmitted current to two LEDs in parallel in order to light them up. Each LED had two 220Ω resistors through which the current exited the LED and green wires that led the current to ground. After calculating this circuit’s values, we used both the resistance equation and Ohm’s Law the same way we had for the first circuit (separating the two LEDs into different circuits and for Ohm’s Law using only the current which passed through the branch). This gave us 106Ω
