CHAPTER 1 HW Solutions 2 Why should a firm like Dell take into account total supply chain profitability when making decisions? Their success rely on competitive advantage.

Also‚ when speaking of cryogenics‚ the terms Celsius and Fahrenheit are rarely used. Instead scientists use a different measurement called the Kelvin (K). The Kelvin scale for Cryogenics goes from 173 K to a fraction of a Kelvin above absolute zero. There are also two main sciences used in cryogenics‚ and they are Superconductivity and Superfluidity. Cryogenics first came about in 1877‚ when a Swiss Physicist named Rasul Pictet and a French Engineer named Louis P. Cailletet liquefied oxygen

Measuring the Speed of Sound and Air using a Pulse-Echo Technique Purpose To determine the speed of sound in air using the pulse-echo experiment procedure‚ and comparing it to the predicted speed of sound in air using the measured air temperature of the classroom. Hypothesis I believe that the speed of sound it the air will be close to that of the predicted value. According to our predicted value‚ we should expect the speed of sound in the air to be at a speed of approximately 346 m/s. Materials
