What is a boundary layer in fluid mechanics? Boundary layer, in fluid mechanics, thin layer of a flowing gas or liquid in contact with a surface such as that of an airplane wing or of the inside of a pipe. The flow in such boundary layers is generally laminar at the leading or upstream portion […]
What is incorrect regarding the output offset voltage of op amp?
What is incorrect regarding the output offset voltage of op amp? What is incorrect regarding the output offset voltage of op-amp? Explanation: Output offset voltage is the output voltage of the op-amp when the input at both terminals is zero. It occurs due to the dissimilarities and mismatches in the internal structure of the op-amp. […]
When can you work on live electrical equipment?
When can you work on live electrical equipment? When is it safe to work on live electrical equipment? It is never absolutely safe to work on live electrical equipment. There are few circumstances where it is necessary to work live, and this must only be done after it has been determined that it is unreasonable […]
How is convection defined?
What is a typical component in the power flow of torque from an engine?
What is a typical component in the power flow of torque from an engine? There are two fan-shaped components inside the torque converter, which is filled with transmission fluid: an impeller, which is attached to the engine’s crankshaft, and a turbine, attached to the transmission’s input shaft. Which of the following is a typical type […]
How does degree of polymerization affect the melting point?
How does degree of polymerization affect the melting point? In general, increasing degree of polymerization correlates with higher melting temperature and higher mechanical strength. What are long chains formed by the process of polymerization? Answer. Answer: Polymerization, any process in which relatively small molecules, called monomers, combine chemically to produce a very large chainlike or […]
What is the mechanism of grain refinement strengthening?
What is the mechanism of grain refinement strengthening? It is based on the observation that grain boundaries are insurmountable borders for dislocations and that the number of dislocations within a grain have an effect on how stress builds up in the adjacent grain, which will eventually activate dislocation sources and thus enabling deformation in the […]
How is the Apriori property used in the algorithm?
How is the Apriori property used in the algorithm? Apriori is an algorithm for frequent item set mining and association rule learning over relational databases. The frequent item sets determined by Apriori can be used to determine association rules which highlight general trends in the database: this has applications in domains such as market basket […]
What are the contributing factors to gender based violence?
What are the contributing factors to gender based violence? Various other factors, such as poverty, lack of education and livelihood opportunities, and impunity for crime and abuse, also tend to contribute to and reinforce a culture of violence and discrimination based on gender. What are factors that contribute to violence? Individual Risk Factors History of […]
How are metallic glasses formed?
How are metallic glasses formed? Explanation: Quenching means rapid cooling. Actually atoms of any material move freely in a liquid state. Atoms can be arranged regularly when a liquid is cooled slowly. Instead, when a liquid is quenched, there will be an irregular pattern, which results in the formation of metallic glasses. What are metallic […]
