What happens to electrons when they reach a light bulb? 2 Answers. Electrons are accelerated by the field inside the incandescent filament (the voltage drop over the light bulb is large, the field is relatively strong). The electron then interacts with the lattice, losing its energy to thermal vibrations. Then gets accelerated again, etc. Is […]

Will wind ever stop blowing?
Will wind ever stop blowing? Wind is the atmosphere trying to reach a pressure equilibrium. If the pressure is equalized, there will be no more wind. Which is rare on our planet as different areas are always heating and cooling. Hotter air is lower pressure and cooler air is higher pressure. Where on earth is […]
What is an example of a force multiplier?
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) […]
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 […]
Where an object is located in relation to another object?
Where an object is located in relation to another object? 7.1 An object is in motion if its position changes relative to another object. To decide if you are moving, you can use your chair as a reference point. A reference point is a place or object used for comparison to determine if something is […]
What happens if mass and velocity are doubled?
What happens if mass and velocity are doubled? Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum. What happens to the kinetic energy when the mass and velocity is […]
Does it mean if data are reproducible but not accurate?
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 […]
Is rock a fossil?
Is rock a fossil? Fossils are the preserved remains, or traces of remains, of ancient organisms. Fossils are not the remains of the organism itself! They are rocks. Bones, shells, feathers, and leaves can all become fossils. Who is the most famous paleontologist in the world? Jack Horner Do you need a PhD to be […]
