What is ionized helium? Singly ionized helium is an atom that has lost one of its electrons. We must expect its remaining electron to act like a hydrogen electron. There is only one difference between a hydrogen atom and a singly ionized helium atom; number of protons in the nucleus, so the nuclear charge. What […]

How much does it cost to replace seatbelts? The cost of a replacement seat belt varies depending on your vehicle’s specific year, make, and model. OE replacement parts will generally cost you anywhere between $20 to $85. Replacement seat belt assemblies are usually sold individually. Can seat belts be repaired or are they to be […]

Can a person live without bone marrow? It is the blood cell ‘factory’. Healthy bone marrow releases blood cells into the bloodstream when they are mature and when required. Without bone marrow, our bodies could not produce the white cells we need to fight infection, the red blood cells we need to carry oxygen, and […]

What are the important topics in electric charges and fields? Important Topics: Coulomb’s Law. Forces between multiple charges electric field due to system of charges. Electric dipole’s electric field on axial and equatorial point. Electric dipole in external electric field. Gauss’s law applications. What are the most important topics in physics? NEET 2021 Class 12th […]

What were the major conflicts of the Cold War? The Korean War, Vietnam War, and a number of other armed conflicts, during which both sides either funded one side of the war or fought directly against a communist or capitalist force, are all considered Cold War proxies. Why the US was responsible for the Cold […]

Why is area and perimeter important? Perimeter and Area. Perimeter and area are two important and fundamental mathematical topics. They help you to quantify physical space and also provide a foundation for more advanced mathematics found in algebra, trigonometry, and calculus. What is the importance of perimeter in real life? In everyday life area and […]

How do rockets rotate? In flight, any rocket will rotate about its center of gravity, a point which is the average location of the mass of the rocket. Most rockets are symmetric about a line from the tip of the nose to the center of the nozzle exit. We will call this line the roll […]

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 […]

How does physics help us in our daily lives? Physics generates fundamental knowledge needed for the future technological advances that will continue to drive the economic engines of the world. Physics contributes to the technological infrastructure and provides trained personnel needed to take advantage of scientific advances and discoveries. What is physics in everyday life […]

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 […]
