What is the working principle of inductor? An inductor is a passive electronic component which is capable of storing electrical energy in the form of magnetic energy. Basically, it uses a conductor that is wound into a coil, and when electricity flows into the coil from the left to the right, this will generate a […]
Who found solar energy?
Who found solar energy? A solar cell is a device that converts light directly into electricity using the photoelectric effect. The first solar cell was constructed by Charles Fritts in the 1880s. How do we convert solar energy into electricity? When light energy from the sun strikes a photovoltaic solar cell, it energizes the cell […]
Is EMF sensitivity a real thing?
Is EMF sensitivity a real thing? Electromagnetic hypersensitivity (EHS) is a claimed sensitivity to electromagnetic fields, to which negative symptoms are attributed. EHS has no scientific basis and is not a recognised medical diagnosis. Does electromagnetic waves effect on human body? The main effect of radiofrequency electromagnetic fields is heating of body tissues. Despite extensive […]
How expensive is a dock?
How expensive is a dock? On average, expect to pay $8,000 to $30,000 for a standard sized permanent boat dock. For a very small dock, you may get away with paying as little as $5,000. Piling docks cost $20 to $40 per square foot including installation. The most expensive types of docks usually max out […]
Is C3H8 O2 CO2 H2O balanced?
Why do superconductors float?
Why do superconductors float? At normal temperatures, magnetic fields can pass through the material normally. When a magnet is placed above a superconductor at critical temperature, the superconductor pushes away its field by acting like a magnet with the same pole causing the magnet to repel, that is, “float”—no magical sleight of hand required. Can […]
What are two requirements for current flow?
What are two requirements for current flow? To produce an electric current, three things are needed: a supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges. The pathway to carry the charges is usually a copper […]
Is friction necessary for a body to roll?
Is friction necessary for a body to roll? Yes friction is necessary to the body to roll. The minimum friction is that when the body moves easily by using 1 Newton of force. How is the draft calculated in rolling? Explanation: During rolling process, the workpiece gets squeezed, causing the thickness of the workpiece to […]
Is there anything more powerful than gamma rays?
Is there anything more powerful than gamma rays? The measurement is exceedingly difficult since cosmic rays can outnumber gamma-rays at these energies by a factor of 10,000 to 1 or more! As the gamma-ray is making its way to our telescopes, it has to traverse through space, where there are photons and particles all around […]
What are the themes of Native American literature?
What are the themes of Native American literature? Though each nation has its own stories, several themes that are common across the tribes are the link between the land and the people, a hero’s journey, and the supernatural and natural worlds. American Indian stories influenced and helped shape later American literature. What are 5 characteristics […]
