Does all motion stop at absolute zero? The quick answer to your question is no, molecules do not stop moving at absolute zero. They move much less than at higher temperatures, but they still have small vibrations at absolute zero. Because molecules are very small, their movement is governed by the laws of quantum mechanics. […]
What is the purpose of flue gas analysis?
What is the purpose of flue gas analysis? A flue gas analyzer will enable you to measure the concentrations of various gases and adjust burners on a boiler to help achieve optimal combustion. Efficient combustion also reduces emission of pollutants such as nitric oxide (NO), nitrogen dioxide (NO2), sulfur dioxide (SO2), and particulate matter. What […]

How many degrees of freedom does a planar joint have? three degrees How many rotational and translational degrees of freedom does a fixed wing aircraft have? In three degree of freedom the flight dynamics has one […]
Which of these is an accurate description of arc welding and cutting?
Which of these is an accurate description of arc welding and cutting? Arc Welding/Cutting. In arc welding, the intense heat needed to melt metal is produced by an electric arc. The arc is formed between the actual work piece and an electrode (stick or wire) that is manually or mechanically guided along the joint. Oxides […]
What is the function of a heat engine?
What is the function of a heat engine? In thermodynamics and engineering, a heat engine is a system that converts heat or thermal energy to mechanical energy, which can then be used to do mechanical work. It does this by bringing a working substance from a higher state temperature to a lower state temperature. What […]
What are the advantages of using a command line vs a GUI?
How do you calculate PSIA to PSIG?
What are the 7 design principles and elements?
What are the 7 design principles and elements? The 7 principles of art and design are balance, rhythm, pattern, emphasis, contrast, unity and movement. Use the elements of art and design – line, shape/form, space, value, color and texture – to create a composition as a whole. The elements of art and design are the […]
What is the 21st number in the Fibonacci sequence?
What is the minimum depth of an outlet box?
What is the minimum depth of an outlet box? 1.5 inches deep How deep are electrical boxes? Square boxes come in standard depths of 1 1/4 to 2 1/8 inches, but their square corners give them additional interior space, providing maximum volume for multiple conductors and connectors. For this reason, 4-inch square boxes often are […]
