What are the 6 constraints of a project?
What are the 6 constraints of a project? To remember the Six Constraints, think “CRaB QueST” (Cost, Risk, Benefits, Quality, Scope and Time). What are the 3 types of project constraints? The three primary constraints that project managers should be familiar with are time, scope, and cost. These are frequently known as the triple constraints […]
What kind of applications require real time data warehousing?
What kind of applications require real time data warehousing? So, data warehousing allows you to aggregate data, from various sources. This data, typically structured, can come from Online Transaction Processing (OLTP) data such as invoices and financial transactions, Enterprise Resource Planning (ERP) data, and Customer Relationship Management (CRM) data. What are different types of data […]
Why multimeter or voltmeter does not give more accurate reading of voltage?
Why multimeter or voltmeter does not give more accurate reading of voltage? Answer: Voltmeter is accurate for voltage and ammeter is accurate for current measurement. This is because a high current of the order of few hundreds or thousand amperes cannot be taken directly by any ammeter. The current , sometimes for calibration, is generated […]
What does phase transformation involve?
What does phase transformation involve? A phase transformation occurs when one material changes its composition or structure. The transformation can be caused by a change in temperature so that no other material is involved or it may involve the reaction with another material, which may or may not be a ceramic, and may be in […]
What happens if a resistor burns out?
What happens if a resistor burns out? When a resistor breaks down, current typically flows through the burnt resistor without any resistance and thereby passes unchecked. Other components in the circuit may become damaged from the excess current flowing through. What can I use instead of a resistor? Explained another way: an electrical circuit that […]
Can you undo recently deleted?
Can you undo recently deleted? If you delete them from the “Recently Deleted” folder, there will be no other way to recover permanently deleted photos from your device, except from a backup. You can find the location of this folder by going to your “Albums”, and then tap on the “Recently Deleted” album. Select the […]
What is one way property in hash function?
What is one way property in hash function? A one-way hash function, also known as a message digest, is a mathematical function that takes a variable-length input string and converts it into a fixed-length binary sequence that is computationally difficult to invert—that is, generate the original string from the hash. What is a hash function […]
What is Burger vector in edge dislocation?
What is Burger vector in edge dislocation? The Burgers vector associated with a dislocation is a measure of the lattice distortion caused by the presence of the line defect. Because of the absence of a dislocation within this circuit, it fails to close on itself, and the vector linking the end of the circuit to […]
How much heat can a PCB take?
How much heat can a PCB take? The PCBs maximum operational temperature is 120°C. What is PCB temperature? PCBs are typically defined as high-temperature PCBs if they can withstand temperatures of 150 degrees Celsius. Some high-temperature PCBs may be able to withstand even higher heats, but boards manufactured from materials with less heat resistance will […]
