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 […]

What happens to torque if field is non-uniform? An electric dipole always experiences a torque when placed in uniform as well as non-uniform electric field. But in non-uniform electric field, dipole will also experience net force of attraction. So the electric dipole in non-uniform electric field experiences both torque and force. What is meant by […]

What two factors can make an object stable? The stability of an object is dependent on two factors: The base width of the object. The center of gravity. What are structures for Grade 3? A structure is a solid that has a shape, size, and purpose. It holds a load. Example: A tennis shoe is […]

How do you use the word use and used? Used to refers to something familiar or routine, as in “I’m used to getting up early for work,” or to say that something repeatedly happened in the past like “we used to go out more.” Use to typically occurs with did; “did you use to work […]

Why do bats die near wind turbines? When a wind turbine’s blades move, they cause a drop in nearby air pressure. If a bat flies too close to a turbine, this drop in air pressure can damage its lungs. They found that each wind turbine kills around 5 birds and 12 bats every year! How […]

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 […]

Which type of motion is of a girl sitting in a moving merry go round? circular motion What net force is acting on her if she is standing on the merry go round? Question: What Net Force Is Acting On Her If She Is Standing On The Merry -go-round 1.2 M From Its Center In […]

What is the SI unit of only current? ampere Can I use 110v in USA? It will be just fine, as long as your electricity is running to US spec. It really can be anywhere from 110V to 120V +/- 5%. Can I plug 120V into 110v? In the US, 110V isn’t a standard voltage. […]

What is the property of minerals that reflects light? Luster What are the two major properties of minerals? A mineral species is defined by two distinct properties: (1) its chemical com- position and (2) its crystal structure. Each mineral has a distinct three- dimensional array of its constituent atoms. This regular geometry affects its physical […]
