Why do metals have body-centered face-centered and hexagonal centered structures? eight strong bonds to the atoms that it touches and six weaker bonds to the atoms it almost touches. This makes it easier to understand why a metal might prefer the body-centered cubic structure to the hexagonal or cubic closest-packed structure. Is face-centered cubic close […]
What is transaction in database management system?
What is transaction in database management system? A Database Transaction is a logical unit of processing in a DBMS which entails one or more database access operation. All types of database access operation which are held between the beginning and end transaction statements are considered as a single logical transaction in DBMS. What is transaction […]
What are the first three steps in the scientific method?
What are the first three steps in the scientific method? The scientific method Make an observation. Ask a question. Form a hypothesis, or testable explanation. Make a prediction based on the hypothesis. Test the prediction. Iterate: use the results to make new hypotheses or predictions. What are the 3 types of scientific methods? Scientists use […]
What are the methods for drawing isometric views?
What are the methods for drawing isometric views? Following method is used for drawing isometric scale: After drawing a horizontal line, draw two lines at 45° and 30° angle with it. Put marks on the 45° line according to the actual scale. Now draw perpendicular offsets from 45° line up to 30° line which will […]
What are the major hurdle of pipelining pipelining hazards?
What are the major hurdle of pipelining pipelining hazards? The Major Hurdle of Pipelining Control hazards—arise from changing the PC such as branch instructions For branch-taken situation, the instruction fetch is not in regular sequence, the target instruction is not available. Simple solution to the hazards → stall the pipeline. How do you overcome hazards […]
How does an automatic gear work?
How does an automatic gear work? An automatic transmission uses sensors to determine when it should shift gears, and changes them using internal oil pressure. As you push the throttle to speed up, the fluid moves the turbine faster to send more power through the transmission. Why do manual cars jerk? Ordinarily, working transmissions keep […]
How does temperature affect the Nernst equation?
How does temperature affect the Nernst equation? Temperature does not affect Nernst equation. The variation of cell potential is linear with temperature. Nernst equation shows that cell potential decreases as temp increases if reaction quotient is not one and other terms stay constant. Does temperature affect Ecell? A. Temperature does not affect the e-cell when […]
Does capacitance increase with frequency?
Does capacitance increase with frequency? Capacitance does not change with frequency. Rather it’s the capacitive reactance that actually changes with frequency. Capacitance is simply the charge in a capacitor per voltage across its plates. What happens to capacitive reactance as the frequency of operation increases? The capacitive reactance of the capacitor decreases as the frequency […]
What is essentially the engine block of the rotary engine?
What is essentially the engine block of the rotary engine? The cooling system uses a standard radiator, thermostat, and radiator hoses. Water flows from the radiator to the water pump then into the rotor housing, which is essentially the engine block of the rotary engine; this is where the rotor moves. What is the bottom […]
What is a solution question?
What is a solution question? Below are four ways to recognize if your question is solution-oriented: It is a closed question. It asks for agreement with a proposition—would you, could you, shouldn’t you, how about if you. You can subtract a few words from the front and get a statement. The coach is proposing a […]
