What is the first step of the engineering design process? The steps: ask to identify the need and constraints, research the problem, imagine possible solutions, plan by selecting the most promising solution, create a prototype, test and evaluate the prototype, and improve and redesign as needed. Also called the engineering design process. How many steps […]

What is the use of 7 segment display? A seven-segment display is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays. Seven-segment displays are widely used in digital clocks, electronic meters, basic calculators, and other electronic devices that display numerical information. What is […]

What is the role of an accumulator? Accumulator is a pressure vessel for storing hydraulic pressure in it utilizing compressible and decompressible nature of nitrogen gas. So, it can be said that the accumulator has a similar function to the rechargeable electrical battery. In electricity, electrical energy is stored to the battery. What is an […]

Which amplifier has maximum bandwidth? 3) In the class of all amplifiers with dc gain K, > 1 + fi, monotone frequency response, using only resistors and at most two operational amplifiers, and with output taken from the output of an operational amplifier, Circuit 5 has the largest bandwidth. What is bandwidth of a signal? […]

What are the two components of an instruction what information do these two components contain? The two components of an instruction are the opcode and the operands. The opcode component contains the information of what the instruction does. The operands component contains the information of who it is to do it to . You’ve reached […]

What does plastic deformation do on crack propagation? Since plastic deformation in metals proceeds mainly through dislocation slip and/or twinning [4,6], it can be expected that the evolution of a crack-tip during crack initiation and propagation will be strongly influenced by the local deformation mechanisms [7]. Which theory explains brittle fracture? Orowan and Irwin theory […]

What were the three compromises regarding slavery? The three major compromises were the Great Compromise, the Three-Fifths Compromise, and the Electoral College. What was the North’s position on slavery? American attitudes to slavery were complex with much disagreement; however, before emancipation, many northerners felt guilty about slavery and white southerners expected federal protection of the […]

What causes tides high and low? They are caused by the gravitational forces exerted on the earth by the moon, and to a lesser extent, the sun. When the highest point in the wave, or the crest, reaches a coast, the coast experiences a high tide. When the lowest point, or the trough, reaches a […]

How do you pass a variable from one class to another? You can create the object of one class and using this object you call other class variables and methods, but make sure the accessiblity will be as public. We can use interface class A and by implementing A into B, can use the variable […]

What was the leading source of energy in the United States in 2017? “The three major fossil fuels—petroleum, natural gas, and coal—combined accounted for about 77.6% of the U.S. primary energy production in 2017: Natural gas: 31.8% Petroleum (crude oil and natural gas plant liquids): 28% Coal: 17.8% What is US electricity generation by energy […]
