the print head contains small chambers of heated liquid ink that squirts onto the paper through tiny nozzles. for laser printers, an electrical charge is used to attract toner particles to certain parts of the page, which creates an image on the paper. how can i keep my printer in good ...
The fan from the indoor unit pulls hot air from inside the house through return air ducts. This heat from the air passes through filters where dust, lint and other airborne particles are collected. The filtered, warm indoor air then passes over cold evaporator coil. As the liquid refrigerant...
In terms of attractive forces and kinetic energies of particles, explain what happens during the freezing process. What happens to convection currents when liquid or gas is no longer heated? What is happening to the bonds in the rising and falling portions of a heating and cooling curve? What ...
Thanks to our old friend wave-particle duality, electrons (which we normally think of as particles) can behave like waves (just as waves of light can behave like particles). The faster they travel, the smaller the waves they form and the more detailed the images they show up. Having ...
Look at the back of a sticky note using an electron microscope and you'll see not a continuous film of adhesive but lots of microscopic glue bubbles, known as microcapsules, which are about 10–100 times bigger and much weaker than the glue particles you'd find lazing around on normal ...
When present, it is located along the gust front and most frequently observed on the leading edge of a line of thunderstorms. The roll cloud will appear to be slowly "rolling" about its horizontal axis. Roll clouds are not and do not produce tornadoes. Top Sandstorm Particles of sand ...
Shohini Gose quantum physicist says in her TED talk that quantum physics describes the behaviour of atoms and fundamental particles, like electrons or photons. A quantum computer operates by controlling the behaviour of these particles, which is very different from the way our traditional computers wo...
The powder material is heated to just below its melting point and spread over the build platform in a very fine layer. A laser or electron beam is then directed across the powder’s surface, fusing particles together to form a single cross-section of the print. After each layer, the ...
What effect does heating a gas have on the particles that make up that gas? How are air masses classified? Explain the relationship between the characteristics of air masses and source regions. Why do current flows in the opposite direction of electrons movement?
Also, in the case of extreme mechanical failures, parts of the driveline may attempt to leave the vehicle at high speed. With all the potential for flying particles, keep a good distance from any car doing a burnout. Front, Rear, and All Wheel Drive Rear wheel drive cars are generally th...
