Which stage lasts the longest? The Star remains the longest in the stage when it is burning Hydrogen into Helium. For our Sun this is called the main sequence stage which will last for about 4.5 Billion years more , this depends on how fast the star is burning up fuel. For more massive stars […]
What are inductors and capacitors used for?
What are inductors and capacitors used for? Capacitors and inductors are electronic components that can store energy supplied by a voltage source. A capacitor stores energy in an electric field; an inductor stores energy in a magnetic field. How are capacitors and inductors used together? Inductors that share the magnetic path are combined together and […]
Are slow oxidative fibers fatigue resistant?
Are slow oxidative fibers fatigue resistant? The three types of muscle fibers are slow oxidative (SO), fast oxidative (FO) and fast glycolytic (FG). Slow oxidative fibers use aerobic metabolism to produce low power contractions over long periods and are slow to fatigue. Which type of fiber is best if you need a quick burst of […]
What is the distance a screw thread advances axially in one turn called?
What is the distance a screw thread advances axially in one turn called? Lead What are the different types of screw threads? Clamp screws come in many forms. There are Standard threads, ACME threads, Buttress threads, and Square threads. Each of these threads may be used in clamps and vises for different reasons. What are […]
Is infrared reflected by mirrors?
Is infrared reflected by mirrors? Do mirrors reflect only visible lights, or do they reflect light of other frequencies (if so then which types–x-ray, infrared, gamma, etc)? Yes and no, a normal mirror reflects visible light and likely near IR and UV, but it’s not optimized for anything past that. Do Humans give off infrared […]
What are divisible by 5?
What is interspecific crossing?
What is interspecific crossing? An interspecific hybrid is a cross between plants in two different species. Many times they will be from the same genus, but not always. In animals, hybridization often results in sterility or low fertility, but this is less often the case with plants. What is the example of interspecific hybridization? Crossing […]
How do you balance the combustion of glucose?
How do you balance the combustion of glucose? The complete combustion of glucose will give carbon dioxide and water, therefore, the balanced chemical equation can be written as: C6H12O6(s)+6O2(g)→6CO2(g)+6H2O(g) What type of reaction is C6H12O6 c2h5oh CO2? C 6H 12O 6 is both an oxidizing and a reducing agent (disproportionation (dismutation)). This is a gas […]
What is the force of air?
What is the force of air? Air resistance is a force that affects objects that move through the air. It depends on the density of the air, the area of the object, the velocity it is moving, and a “drag coefficient” that accounts for other properties of the object like the surface roughness, and turbulence.
