Why do drums not have pitch? The drum is still tuned to a specific interval and most ears can’t hear the pitch. Its the duration of the sound that allows one to ignore the pitch and thus does not interfere with the melody and harmony. Do kick drums need to be in Key? The key […]
What is difference between gas turbine and steam turbine?
What is difference between gas turbine and steam turbine? The primary difference between steam and gas turbines is the fact that steam turbines receive power from expanding steam. Fuels such as natural gas can heat condensed water in a boiler, but it’s also possible to utilize renewable thermal energy for this heating. This water-based cycle […]
What does L * a * b * stand for?
What does L * a * b * stand for? The CIELAB color space also referred to as L*a*b* is a color space defined by the International Commission on Illumination (abbreviated CIE) in 1976. It expresses color as three values: L* for perceptual lightness, and a* and b* for the four unique colors of human […]
What is the difference between system and control volume?
What is the difference between system and control volume? A control volume is quite a specific concept – a region of space inside some closed surface. Control volume is almost always of finite dimensions and with well defined boundary. A system is a more general concept – a set of objects, usually sharing some property. […]
How do you find the length if you have the width and height and volume?
In which phase changes is heat removed?
In which phase changes is heat removed? If heat is removed from a substance, such as in freezing and condensation, then the process is exothermic. In this instance, heat is decreasing the speed of the molecules causing them move slower (examples: liquid to solid; gas to liquid). These changes release heat to the surroundings. What […]
How do you identify an informal fallacy?
How do you identify an informal fallacy? An informal fallacy occurs because of an error in reasoning. Unlike formal fallacies which are identified through examining the structure of the argument, informal fallacies are identified through analysis of the content of the premises. What is an example of red herring fallacy? This fallacy consists in diverting […]

How does Niagara Falls generate electricity?
How does Niagara Falls generate electricity? Starting over one hundred years ago, power companies have used water in the Niagara River to generate electricity. Instead, about a mile above the falls, much of the river is diverted into pipes which lead it downwards to the generating stations. Once the water reaches the stations, it is […]
Why does air escape from a balloon?
Why does air escape from a balloon? As the surface stretches to inflate, the surface becomes so thin in some places that tiny, microscopic holes result. Air molecules are able to slowly diffuse, or escape, via the surface of the balloon, or tiny holes in the know you tied to keep the darn thing closed. […]
