Can we run out of freshwater? While our planet as a whole may never run out of water, it’s important to remember that clean freshwater is not always available where and when humans need it. In fact, half of the world’s freshwater can be found in only six countries. More than a billion people live […]
What is the safest imaging technique?
What is the safest imaging technique? Ultrasound is the safest known medical imaging modality and can be used by nearly every patient with little to no risk. Ultrasound is safe for even unborn fetuses and those who cannot use other modalities. What is a general imaging exam? A type of test that makes detailed pictures […]

Do all things have energy?
Do all things have energy? Everything is energy, and everything is connected to everything else through fi elds. The quantum theory researchers discovered the answer: Not only do particles consist of energy, but so does the space between. This is the so-called zero-point energy. Therefore it is true: Everything consists of energy. Who said everything […]
What is condition for no refraction?
What is condition for no refraction? If the refractive indices are same in both medias then there will be no refraction and light will pass without any refraction. And when the incident ray is striking perpendicular to one media to another the light will pass without any refraction. What are the two requirements for refraction? […]
Where does the process of subduction occur?
Where does the process of subduction occur? Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle. Regions where this process occurs are known as subduction zones. What happens at a […]
What is reverse inversion?
What is reverse inversion? Inversion is the practice of thinking through problems in reverse. It’s asking how an endeavor could fail, and then being careful to avoid those pitfalls. This idea comes originally from algebra, where an equation is oftentimes easier to solve if you invert it. But it also works for non-math problems. What […]
What are the three basic parts of an electric generator?
What are the three basic parts of an electric generator? The main components of an electric generator can be broadly classified as follows: Engine. Alternator. Fuel System. Voltage Regulator. Cooling and Exhaust Systems. Lubrication System. Battery Charger. Control Panel. What parts are found in an electric generator? Generators convert a fuel source into usable energy […]
How do you express the life of bearing?
How do you express the life of bearing? Bearing life is usually expressed as the number of hours an individual bearing will operate before the first evidence of metal fatigue develops. The usual life rating for industrial applications is called “L-10” life. Simply put the L-10 life is the number of hours in service that […]
