Is TMI still dangerous?
Is TMI still dangerous? After a disaster occurs, many people flee the area, but a small number of people stay and try to rebuild. Sometimes, like in the case of Three Mile Island, the situation still remained too dangerous for residents to stay. It’s been 32 years since the worst nuclear accident in U.S. history […]
How much hydrogen is needed to run an engine?
How much hydrogen is needed to run an engine? This means that for complete combustion, 34 pounds of air are required for every pound of hydrogen. This is much higher than the 14.7:1 A/F ratio re- quired for gasoline. Since hydrogen is a gaseous fuel at ambient conditions it displaces more of the combustion chamber […]
What 3 characteristics did Mendeleev use to organize the elements?
What 3 characteristics did Mendeleev use to organize the elements? In his periodic table, Mendeleev arranged elements in rows by increasing atomic mass. Within a row, elements with lower atomic masses were on the left. Mendeleev started a new row every time the chemical properties of the elements repeated. Thus, all the elements in a […]
Is frequency directly proportional to wavelength?
Is frequency directly proportional to wavelength? Wavelength is commonly designated by the Greek letter lambda (λ). Assuming a sinusoidal wave moving at a fixed wave speed, wavelength is inversely proportional to frequency of the wave: waves with higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths. Are frequency and pitch directly related? Frequency […]
