Where is SF6 used? SF6 gas is extremely chemically stable, non-flammable and highly electronegative, with an excellent dielectric property of approximately 2.5 times more than air. Therefore, it is commonly used in electrical switchgear, transformers and substations as an electrical insulation, arc quenching and cooling medium. What is the major drawback of using SF6 circuit […]
Why is frequency and wavelength important in ultrasound?
Why is frequency and wavelength important in ultrasound? An ultrasound wavelength distance is the physical limit beyond which two structures in space cannot be distinguished. Hence, the smaller the wavelength (i.e., the higher the frequency), the greater the ability to distinguish two points in space that are very close to each other. How does changing […]

Is momentum ever not conserved?
Is momentum ever not conserved? Momentum is an important quantity because it is conserved. Yet it was not conserved in the examples in Impulse and Linear Momentum and Force, where large changes in momentum were produced by forces acting on the system of interest. The only unbalanced force on each car is the force of […]
Does aspirin help blood clots?
Does aspirin help blood clots? The clot can stop blood flowing to the heart or brain and cause a heart attack or stroke. If you take it every day, low-dose aspirin stops platelets clumping together to form unwanted blood clots – and prevents heart attacks and stroke. How do you get rid of blood clots […]
How long do cypress trees live?
How long do cypress trees live? 600 years Do squirrels eat Cypress balls? Bald cypress cones don’t strictly resemble most conifers’ cones. The cone is, like those of most conifers, made of many scales, each of which has two triangular seeds. These seeds are eaten by many animals, including squirrels, wild turkeys, wood ducks, and […]
