Why are electromagnets used? Why are sickle cells and platelets important? Why are lateral roots endogenous? Why is methane a greenhouse gas? Why don't polar molecules diffuse? Why is oxygen not a greenhouse gas? Why is the cochlea filled with fluid?
Specimens are cut into extremely thin sections, and the transmission electron microscope aims an electron beam through a section, just as a light microscope aims a beam of light through a specimen. However, instead of lenses made of glass, the transmission electron microscope uses electromagnets as...

Enter, after many years of planning, the Large Hadron Collider (LHC), an experiment massive enough to potentially falsify the theory of the Higgs boson. The 17-mile loop of super-powered electromagnets can accelerate charged particles to significant fractions of the speed of light, causing collisi...
Laser; Lasers are classified into atomic gas lasers, molecular gas lasers, and ion gas lasers. When electrons in glass or crystal atoms absorb the energy from light or electrical current, a laser is created. Answer and Explanation: Learn more about this topic: ...
Why are electromagnets used? Why doesnt refraction happen at a curved surface? Why can't solids be compressed? Why metals are opaque. Why do photoreceptors respond to the logarithm of luminance? Why are crystalline solids brittle? Why are transition metal compounds often used in paint pigments?
In the majority of cases, all these operations are carried out by electrical devices: - resistances (heating), - motors (stirrers, pumps, compressors...), - electromagnets (electrovalves), Automation in rhe organic chemistry laboratory 1675 - radiating devices: infrared, ultraviolet, ultrasonics ...
Why are so few companies truly innovation? Innovation is key to business survival, and companies put substantial resources into inspiring employees to develop new ideas. There are, nevertheless, people working in luxurious, state-of-the-art centres designed to stimulate innovation who find that their...
Since when are machines required to follow living creatures as a model? Have you ever seen an animal with a transmission and wheels? How about the inner workings of a generator such as electromagnets? Aug 26, 2012 #50 kushan 256 0 Well , I read something about evolution . I can say...
Hi, I am thinking of doing my next science fair project on perpetual motion, showing what prevents it from working. I am thinking of getting a 1-2 foot...
