Handout Cases on Revenue Recognition CASE 1 The Sea-Soft Water Company distributes its water softeners to dealers upon their request. The contract agreement with the dealers is that they may have 90 days to sell and pay for the softeners. Until the 90-day period is over‚ any softeners may be returned at the dealer’s expense and with no further obligations on the dealer’s part. If the water softeners are damaged while in the hands of a dealer‚ Sea-Soft agrees to accept the return of the

If this did not occur ice could sink and destroy living organism. (sea animals) Thermal properties Water resist temperature change‚ due to high specific heat which in turn helps our body (70% water) keeps the water from overheating or freezing.

An intensive property is a physical quantity whose value does not depend on the amount of the substance for which it is measured. For example‚ the temperature of a system in thermal equilibrium is the same as the temperature of any part of it. If the system is divided the temperature of each subsystem is identical. The same applies to the density of a homogeneous system: if the system is divided in half‚ the mass and the volume change in the identical ratio and the density remains unchanged. According

1. In about 100 words‚ explain why online businesses might have difficulty limiting the effects of their actions to a relatively small geographic area. * The legal concept of jurisdiction on the Internet is still unclear and ill defined. The relationship between geographic and legal boundaries is based on four elements: power‚ effects‚ legitimacy and notice. These elements have helped governments create the legal concept of jurisdiction in the physical world. Because the four elements exist

Properties of Water Lab # 1 Biology 111 January 23‚ 2011 INTRODUCTION With surface tension it is made possible for items such as paper clips to float on water‚ because a molecule within the mass of a liquid encounters gravity to all adjacent molecules in all directions. When you use surfactant substances this creates hydrogen bonds. Purpose of experiment 1 will be to show that once the surfactant substances hits the hydrogen bond pulls down paper clips. Things

Promoting Health Education P1 Explain three different approaches to health education For my health education campaign I have chosen to teach my listeners about sweeteners that are replacing sugar‚ such as Aspartame. Aspartame is made up of three chemicals: Aspartic acid‚ phenylalanine‚ and methanol. NutraSweet‚ Equal‚ Spoonful‚ and Equal-Measure‚ all of these are brand names for aspartame‚ the most popular low-calorie sugar substitute used in more than 90 countries to sweeten foods and beverages

“Is Density An Intensive Property Of Matter?” By: Mikal Hayden - Gates A. Introduction The first unit we learned in chemistry was Alchemy. In this unit I learned about the extensive and intensive properties of matter. An extensive property is a property of matter that depends on the changes of the substances shape or amount. An intensive property is a property of matter that doesn’t depend on the substances shape or amount. The purpose of this investigation was to prove that density is
