What is an example of a force multiplier? Some examples of force multipliers are inclined planes and most levers. Some examples are wheels and axles and third class levers. Simple and complex machines. Machines can be either simple or complex. In which condition machine acts as a force multiplier II speed multiplier? Answer. Answer: a) […]
Can fossils be found in granite?
Can fossils be found in granite? Most scientists will say it is very unlikely for fossils of any kind of be found in granite because granite forms at great depths, under conditions that would obliterate organic tissue. It is possible for the native sedimentary rock possessing fossils to be introduced to magma. What environments are […]
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 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 […]
What is the working principle of inductor?
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 […]
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 […]
What happens to the volume of a gas when you double the number of moles of gas?
What happens to the volume of a gas when you double the number of moles of gas? Le Chatelier’s Principle states that: a) When a system at equilibrium is disturbed , a new equilibrium constant is established. What happens to the volume of gas when you double the number of moles of gas while keeping […]
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 […]
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 […]
