Which fuel cell is widely used to generate electricity in vehicle? The most common type of fuel cell for vehicle applications is the polymer electrolyte membrane (PEM) fuel cell. In a PEM fuel cell, an electrolyte membrane is sandwiched between a positive electrode (cathode) and a negative electrode (anode). What is a fuel cell for […]
What is metal transfer in welding?
What is metal transfer in welding? In short circuiting metal transfer, also known as ”Short Arc”, ”Dip Transfer”, and ”Microwire”, metal transfer occurs when an electrical short circuit is established. This occurs as the molten metal at the end of the wire touches the molten weld pool. How is deposition calculated in welding? Calculate the […]
Why does my car engine sound different?
Why does my car engine sound different? Sometimes the loud engine sounds you hear aren’t due to the engine having a problem at all. Instead, it could be caused by a damaged or failing muffler. If it just seems like your car is running louder than it used to, but there aren’t other strange sounds, […]
What statement best describes a variable and its primary purpose?
What statement best describes a variable and its primary purpose? What statement best describes a variable and its primary purpose? A variable is a named storage location in the computer’s memory used for holding a piece of information. This step will uncover any syntax errors in your program. What best describes a variable? A variable […]
What is initial set?
What is initial set? 1. A degree of stiffening of a mixture of cement (or concrete or mortar) and water less than final set; generally stated as the time required for cement paste to stiffen sufficiently to resist the penetration of a weighted test-needle. 2. What is initial and final setting of cement? Initial setting […]
What is an anisotropic material?
What is an anisotropic material? Anisotropic Materials. Anisotropic materials are materials whose properties are directionally dependent. Unlike. isotropic materials that have material properties identical in all directions, anisotropic material’s properties such as Young’s Modulus, change with direction along the object. Why is anisotropy important? Anisotropy measures describe the directional dominance of water diffusion within a […]
What happens if you touch a downed power line covered or bare?
What are the three main parts of a battery?
What are the three main parts of a battery? There are three main components of a battery: two terminals made of different chemicals (typically metals), the anode and the cathode; and the electrolyte, which separates these terminals. The electrolyte is a chemical medium that allows the flow of electrical charge between the cathode and anode. […]
What standard feature is on all circular saws?
What standard feature is on all circular saws? What standard feature is on all circular saws? Most circular-saw blades are carbide-tipped. What height or depth should the saw blade be adjusted to? The Safest Cut With that in mind, the safest height to set a table saw blade is so it’s just above the wood […]
What are the units for heat transfer coefficient?
What are the units for heat transfer coefficient? The overall heat transfer coefficient, or U-value, refers to how well heat is conducted through over a series of resistant mediums. Its units are the W/(m2°C) [Btu/(hr-ft2°F)]. How do you calculate total heat flow? To calculate the amount of heat released in a chemical reaction, use the […]
