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 happens when the resultant force is 0?
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 […]
What is the resultant of two vectors?
What is the effect of temperature on diode?
What is the effect of temperature on diode? Reverse saturation current (IS) of diode increases with increase in the temperature the rise is 7%/ºC for both germanium and silicon and approximately doubles for every 10ºC rise in temperature. Thus if we kept the voltage constant, as we increase temperature the current increases. What is the […]
Which area is most likely to support a marsh ecosystem?
Which area is most likely to support a marsh ecosystem? There was a big error in the answer. The correct answer is “sheltered area near an estuary” A salt marsh is a marshy area found near estuaries and sounds. The water in salt marshes varies from completely saturated with salt to freshwater. How do wetlands […]
