What is capacitance and dielectrics? capacitance: amount of charge stored per unit volt. dielectric: an insulating material. dielectric strength: the maximum electric field above which an insulating material begins to break down and conduct. What is resistance and capacitance? Resistance is the measure of the amount of energy dissipated by the resistor. While capacitance is […]

What is kVp vs mAs? * kVp: the power and strength of the x-ray beam (quality of the x-rays). * mAs: the number of x-ray photons produced by the x-ray tube at the setting selected (quantity of x-rays). * time: how long the exposure lasts. Understanding Technique. kVp stands for kilovoltage peak. What is source […]

Does each nostril go to each lung? Did you know that your nose and mouth are connected? Your nose connects to the back of your mouth through two tubes. The air you breathe in goes from your mouth and nose down to your trachea and into your lungs. What do humans inhale and exhale? When […]

Can current flow through an insulator? In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. Why does current flow in a conductor? When an […]

Is 400 miles to a tank good? Most gas cars don’t make it 400 miles Basically, you need a gas tank size of 13 gallons and an average mpg of 31 to hit – just barely – the 400-mile range mark. At a tank size of 14 gallons, you need to hit 29 mpg, at […]

Malthus argues that population increases exponentially example if a couple have two children and each of those two children have two children the result would be four grandchildren if those four grandchildren each have two children the result to be eight Great grandchildren if a couple […]

What organisms are responsible for nitrogen fixation? Two kinds of nitrogen-fixing microorganisms are recognized: free-living (nonsymbiotic) bacteria, including the cyanobacteria (or blue-green algae) Anabaena and Nostoc and genera such as Azotobacter, Beijerinckia, and Clostridium; and mutualistic (symbiotic) bacteria such as Rhizobium, associated with leguminous plants. How is nitrogen produced? Commercial production of nitrogen is largely […]

Which is short range force? [′shȯrt ¦rānj ′fȯrs] (physics) A force between two particles which is negligible when the distance between the particles is greater than a certain amount; in particular, nuclear forces whose range is several times 10-15 meter. Can Mewtwo defeat arceus? In the movie Arceus and the Jewel of Life, Arceus isn’t […]
