How can we overcome modal dispersion? One way to reduce modal dispersion is to use graded-index fiber. Unlike the two distinct materials in a step-index fiber, the graded-index fiber’s cladding is doped so that the refractive index gradually decreases over many layers. Which type of fiber has highest modal dispersion? Multimode fiber What is difference […]

Which type battery is best? Lithium-ion batteries What kind of batteries are least expensive? The most economical Li-ion battery in terms of cost-to-energy ratio is the cylindrical 18650 cell. Where is the cheapest place to buy batteries? For the best overall prices, consider shopping at one of these top five places to buy cheap batteries: […]

What is the Sun an example? The sun is the star that is the central object in the solar system. It is made up of 92% hydrogen, almost 8% helium and the rest is assorted elements. An example of sun is what rises in the east and sets in the west each day. The radiant […]

What makes it easier to push heavy things answer? Answer: When you push there is one component of force that adds to the weight of the body and hence there is more friction. When you pull the vertical component of force is against the weight of body and hence there is less overall friction. So […]

How do you fix a flooded atomizer? Fold the paper towel several times and hold it against the end of the atomizer. Blow gently through the drip tip until the atomizer stops gurgling. Reassemble the e-cigarette. You should now be able to resume e-smoking. How do you tell if your coil is flooded? The characteristic […]

Does the atomic radius increase from left to right? Atomic radius is determined as the distance between the nuclei of two identical atoms bonded together. The atomic radius of atoms generally decreases from left to right across a period. The atomic radius of atoms generally increases from top to bottom within a group. What is […]

Is it legal to brake check a tailgater? Yes it is illegal to brake check a tailgater. Causing an accident on purpose is illegal. Others have said that you can claim to have seen something dart into the road, but you have still caused an accident. Yes, tailgating is also illegal, but two wrongs do […]

What is the most efficient cycle for a steam power plant? The Rankine cycle is the ideal cycle for vapor power plants; it includes the following four reversible processes: 1-2: Isentropic compression Water enters the pump as state 1 as saturated liquid and is compressed isentropically to the operating pressure of the boiler. What are […]

What are the four stages in the life cycle of a low mass star? Stars about the size of our sun go through the same first four stages as does any other star. They begin their lives as a nebula, then become a Protostar, eventually becoming a main sequence star and finally a red giant. […]

What are two examples of liquid? Examples of Liquids Water. Milk. Blood. Urine. Gasoline. Mercury (an element) Bromine (an element) Wine. What are two examples of a gas? Examples of Gases Hydrogen. Nitrogen. Oxygen. Carbon Dioxide. Carbon Monoxide. Water Vapour. Helium. Neon. What are the common gases? Common gases include Acetylene, Argon, Carbon Dioxide, Helium, […]
