Which type of alternative fuel vehicle is powered by hydrogen? Fuel cell electric vehicles (FCEVs) are powered by hydrogen. They are more efficient than conventional internal combustion engine vehicles and produce no tailpipe emissions—they only emit water vapor and warm air. FCEVs and the hydrogen infrastructure to fuel them are in the early stages of […]

What causes a vehicle to pull to the left or right? One of the Most Common Causes of Pulling is Wheel Alignment The most common reason a car pulls to one side is that the wheel alignment is off. Whether it skews to the side over time, or you hit a particular vicious pothole, wheel […]

What are the 3 degrees of freedom? Three degrees of freedom (3DOF), a term often used in the context of virtual reality, refers to tracking of rotational motion only: pitch, yaw, and roll. What is degrees of freedom robotics? Degrees of freedom, in a mechanics context, are specific, defined modes in which a mechanical device […]

What are the inputs and outputs of a bike? The input is what you put into a bicycle when you ride it. It is the pedalling force and the pedalling speed. In the process box in the middle is the bicycle. The chain drive of the bicycle changes the input pedalling force and pedalling speed […]

How many strokes make up the 2 stroke process? two strokes Do 2 strokes have more power than 4 strokes? Typically, a 2-stroke engine creates more torque at a higher RPM, while a 4-stroke engine creates a higher torque at a lower RPM. That being said, 2-stroke engines are more powerful. Two-stroke engines are a […]

Why is enthalpy usually calculated instead of energy? At constant volume, the heat of reaction is equal to the change in the internal energy of the system. Most chemical reactions occur at constant pressure, so enthalpy is more often used to measure heats of reaction than internal energy. Does enthalpy change with volume? The change […]

What is DFA used for? DFA uses include protocol analysis, text parsing, video game character behavior, security analysis, CPU control units, natural language processing, and speech recognition. What is DFA What is acceptance and rejection in DFA? ○ The algorithm used to determine whether w is in L is modelled using a Deterministic Finite Automaton […]

What can carbon nanotubes be used for? As of 2013, carbon nanotube production exceeded several thousand tons per year, used for applications in energy storage, device modelling, automotive parts, boat hulls, sporting goods, water filters, thin-film electronics, coatings, actuators and electromagnetic shields. Can carbon nanotubes can be used to make lighter stronger building materials? Researchers […]

Does anyone know meaning? This form is principally used to emphasize a fact, particularly to contradict a previous assertion, with emphasis on “does”: “I don’t think anyone knows.” Does anyone know this person? Originally Answered: Which one is correct: anyone know or anyone knows? “Any one” is a pronoun and is singular.As a third person […]

What is periodic function in Fourier series? A Fourier series is an expansion of a periodic function. in terms of an infinite sum of sines and cosines. Fourier series make use of the orthogonality relationships of the sine and cosine functions. How do you find the Fourier transform of a periodic signal? To obtain the […]
