Which of the following locations is permitted for installing the system bonding jumper of a separately derived system? In addition, the system bonding jumper must be installed at the same location where the grounding electrode conductor terminates to the grounded neutral terminal of the separately derived system, which can be at the separately derived system, […]

What are the 5 factors of soil formation? The five factors are: 1) parent material, 2) relief or topography, 3) organisms (including humans), 4) climate, and 5) time. If a single parent material is exposed to different climates then a different soil individual will form. What are the stages of soil development? Three phases can […]

What is scientific problem or question? A scientific problem is something you don’t understand but you can do an experiment to help you understand. Scientific problems are usually based on observation of scientific phenomena. Here is some advice to help you identify a scientific problem you can address by designing your own experiment. What is […]

What is back pressure of turbine? Another steam turbine type is a back-pressure steam turbine, which is the most suitable equipment for mechanical-drive applications, such as the drivers of compressors or pumps. The term back pressure refers to steam turbines that exhaust steam at above atmospheric pressures. Why is it called back pressure turbine? Back […]

What is the function of the brushes? A brush or carbon brush is an electrical contact which conducts current between stationary wires and moving parts, most commonly in a rotating shaft. Typical applications include electric motors, alternators and electric generators. How do I know if my motor brushes are bad? As a general rule, if […]

What is correct rejection? In signal detection theory, an instance of failing to detect a signal when the signal is in fact absent. Also called a correct reject. Compare false alarm (2), hit, miss. Who came up with signal detection theory? Created by Ronald Sahyouni. What are the basic assumptions of signal detection theory? The […]
