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 […]
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 […]
What is the treatment when cell division goes wrong?
What is the treatment when cell division goes wrong? Medicines that are used to treat cancer are sometimes aimed at killing cells that are rapidly dividing by mitosis. They inhibit the synthesis or function of DNA – this type of treatment is called chemotherapy. What will happen if mitosis go wrong? If the process of […]
What are the advantage of rotation magnetic field?
What are the advantage of rotation magnetic field? The advantages of rotating field system are given below. The DC excitation voltage is low and it is very easy to insulate. This intern reduces the size of the machine. c. Out put current can be taken directly from the fixed terminals on the stator. How can […]
How do you find the internal diameter?
How do you find the internal diameter? Calculating the internal diameter depends on the outside diameter and the thickness of the outer circle. Find the total diameter of the object in question by taking a measurement from the outside wall of one side (the point of origination) straight across to the outside wall of the […]
Does cold water help hurricanes?
Does cold water help hurricanes? Once they move over cold water or over land and lose touch with the hot water that powers them, these storms weaken and break apart. Recent studies have shown a link between ocean surface temperatures and tropical storm intensity – warmer waters fuel more energetic storms. What weakens a hurricane? […]
