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 ...
Various boundaries, such as the transition to high confinement, density limits, and power exhaust requirements, impose limits on the safe and efficient ope
But how do we get the sails and their spacecraft into space? Let's take a look. You want holes in the sail? Les Johnson, of Marshall Space Flight Center, holds a rigid, lightweight carbon fiber material that gave many solar-sail-scientists pause for thought. This fiber was a departure...
These trails enabled scientists to more easily find the tiny particles from space. Aerogel's durability allowed the dust collector to return from space intact with not a single aerogel tile missing. Scientists have been able to study the dust and crystals contained in the aerogel and await the ...
For the past 75 years, the vast majority of televisions have been built around the same technology: thecathode ray tube(CRT). In a CRT television, a gun fires a beam ofelectrons(negatively-charged particles) inside a large glass tube. The electrons excitephosphor atomsalong the wide end of...
Sintering is another additive manufacturing technology that involves melting and fusing particles together to print each successive cross-section of an object. Selective laser sintering (SLS) is one form of sintering used in 3D printing. SLS relies on a UV laser beam to melt a flame-retardant pow...
Explain why the temperature of a gas increases when it is adiabatically compressed. What effect does heating a gas have on the particles that make up that gas? A gas expands along path ABC. Find the work done by the gas in this expansion. Why do substances expand when the temperature is...
How do gases differ from liquids?States of Matter:There are four states of matter that are present naturally. These are solid, liquid, gas and plasma. In solids, the particles are arranged in a stable state. Anything that flows is known as fluid. Liquids and gases are known as fluids. ...
How to Tame a Llama in Minecraft After successfully locating the llama, you’re free to tame it. This process is rather similar totaming horses. You’ll need toright-click it to ride it, soon after which the llama will eject you. Repeat this multiple times until you seeheart particlesapp...
Molds can release spores particles into the air, contributing to its spread and potentially harming occupants' health. Other types of microorganism pollutants are bacteria, which are single-cell living organisms that are found all around us, whether on surfaces, air, in the dust, or in the ...
