Is geothermal a source of electricity? Geothermal energy is a renewable energy source because heat is continuously produced inside the earth. People use geothermal heat for bathing, to heat buildings, and to generate electricity. Is geothermal energy harmful to humans? When done properly, yes. As with any industrial project there are risks involved, but when […]
What is B in a sine function?
Why there is a need for scientific knowledge in education?
Why there is a need for scientific knowledge in education? Problem-solving and critical thinking are two of the most important skills students learn in school. In this way, science is one of the most important subjects students study, because it gives them the critical thinking skills they need in every subject. What is the impact […]
What 3 things affect the speed of sound?
What 3 things affect the speed of sound? Factors Affecting The Speed of Sound The Density of Medium: Sound requires a medium to travel. The density of the medium is among the factors which affect the speed of sound. The Temperature of The Medium: Higher the temperature, the higher is the speed of sound in […]
Do electrons know they being observed?
Do electrons know they being observed? This process is sometimes referred to as decoherence. We also see phrases such as “wavefunction collapse”. By virtue of such an interaction of a quantum system with a classical measurement device, one could quite misleadingly assert that the electron “knows” it is being observed. It doesn’t. Why do wave […]
What are 3 organisms?
What are 3 organisms? Organisms are classified by taxonomy into groups such as multicellular animals, plants, and fungi; or unicellular microorganisms such as protists, bacteria, and archaea. What are the 8 organisms? There are different types of organisms, including -producers, consumers, herbivores, carnivores, omnivores, scavengers, parasites, predators, and decomposers. What type of organisms are humans? […]
What materials can you use for magnetic particle inspection?
What materials can you use for magnetic particle inspection? Common metallic materials like nickel, iron, steel, and cobalt are all ferromagnetic and perfect candidates for magnetic particle testing. Where is magnetic particle testing used? Magnetic particle inspection is used for detecting defects (discontinuities in surfaces and shallow subsurfacaes) in ferromagnetic materials. By magnetization of the […]
What is the force of the earth on the moon?
What is the force of the earth on the moon? Sun, Earth, and Moon Gravitational body causing tidal force Tidal force Body Mass (m) Moon 7.34×1022 kg 1.10×10−6 m⋅s−2 Earth 5.97×1024 kg 2.44×10−5 m⋅s−2 m is mass; r is radius; d is distance; 2r is the diameter G is the gravitational constant = 6.674×10−11 m3⋅kg−1⋅s−2 […]
Is selective coordination required?
Is selective coordination required? Selective coordination is required for systems related to life safety (as defined in the NEC), and is achieved when an overcurrent on a circuit is interrupted and only the closest upstream device opens such that only the section of the electrical system with a problem is taken offline. What is selective […]
