What is the pressure ratio of a gas turbine? In aeronautical engineering, overall pressure ratio, or overall compression ratio, is the ratio of the stagnation pressure as measured at the front and rear of the compressor of a gas turbine engine. The terms compression ratio and pressure ratio are used interchangeably. What is back work […]

What is meant by dead state? Dead State – A rejecting state that is essentially a dead end. Once the machine enters a dead state, there is no way for it to reach an accepting state, so we already know that the string is going to be rejected. Transition – A way for a machine […]

How do I renew a VMware certificate? Log in with the vSphere Client to the vCenter Server connected to the Platform Services Controller….Renew the machine SSL certificate for the local system. Select Machine SSL Certificate. Click Actions > Renew. Click Renew. A message appears that the certificate is renewed. What happens if VMware license expires? […]

What is ADC in Arduino? To measure the value of analog signals, the Arduino has a built-in analog-to-digital converter (ADC). The ADC turns the analog voltage into a digital value. The function used to output a PWM signal is analogWrite(pin, value). pin is the pin number used for the PWM output. What is A0 in […]

Is change in entropy a function of temperature? We can express the entropy as a function of temperature and volume. It can be derived from the combination of the first and the second law for the closed system. For ideal gas the temperature dependence of entropy at constant volume is simply Cv over T. What […]

What is energy in terms of electricity? Electrical energy is a form of energy resulting from the flow of electric charge. Energy is the ability to do work or apply force to move an object. The movement of charged particles through a wire or other medium is called current or electricity. What is definition of […]

Which equation can be used to find x the length of the hypotenuse of the right triangle 16 63? Which equation can be used to find x, the length of the hypotenuse of the right triangle? 16 + 63 = x. Which equation can be used to find x the length of the hypotenuse of […]

What are the design patterns used in your project? While class-creation patterns use inheritance effectively in the instantiation process, object-creation patterns use delegation effectively to get the job done. Creational design patterns are the Factory Method, Abstract Factory, Builder, Singleton, Object Pool, and Prototype. What is API design? API design refers to the process of […]

How do you find the density of air with pressure? The Ideal Gas Law Equation Noting that m/V is density, ρ, the equation can be written as P(MW) = (m/V)RT = ρRT. Solving for density gives the following equation for the density of an ideal gas in terms of its MW, pressure and temperature. R […]

What type of energy does flashlight use? electrical energy How does a flashlight transform energy? The battery has chemical energy. When the flashlight is turned on, the chemical energy is first transformed into electrical energy and then into light energy. CHEMICAL bonds. It is released during a chemical reaction (change). Does a flashlight have potential […]
