What happens during precipitation?
What happens during precipitation? Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain. Is precipitate a chemical reaction? Precipitation refers to a […]
What limits the compression ratio in the Otto cycle?
What limits the compression ratio in the Otto cycle? Autoignition – Limit for Compression Ratio The unburned mixture may autoignite by detonating from pressure and heat alone, rather than ignite from the spark plug at exactly the right time. The engine knocking can be reduced by using high-octane fuel, which increases the gasoline’s resistance to […]
How is the scientific method related to the engineering design process?
How is the scientific method related to the engineering design process? Scientists use the scientific method to make testable explanations and predictions about the world. A scientist asks a question and develops an experiment, or set of experiments, to answer that question. Engineers use the engineering design process to create solutions to problems. How is […]
What is no slip condition and what causes it?
What is no slip condition and what causes it? No slip condition exists because of Viscosity. The no-slip condition for viscous fluids assumes that at a solid boundary, the fluid will have zero velocity relative to the boundary. No slip condition exists because of Viscosity. What is a slip wall? The slip wall condition is […]

Why are planetary gears used in automatic transmissions?
Why are planetary gears used in automatic transmissions? An automatic transmission usually has more than one planetary gear set. They work together to create multiple gear ratios. Because the gears are in constant mesh in a planetary gear system, gear changes are made without engaging or disengaging gears, like you do on a manual transmission. […]
What will happen to potato in salt water?
What will happen to potato in salt water? If the salt concentration in the cup is higher than inside the potato cells, water moves out of the potato into the cup. This leads to shrinkage of the potato cells, which explains why the potato strips get smaller in length and diameter. How does temperature affect […]
Which RAM is non volatile?
Which RAM is non volatile? RAM(Random Access Memory) is an example of volatile memory. ROM(Read Only Memory) is an example of non-volatile memory. 5. In volatile memory, data can be easily transferred in comparison to non-volatile memory. Why ROM is non volatile memory? ROM that is read only memory is non volatile because all the […]
