What do you mean by dielectrics? Dielectric, insulating material or a very poor conductor of electric current. When dielectrics are placed in an electric field, practically no current flows in them because, unlike metals, they have no loosely bound, or free, electrons that may drift through the material. What is dielectrics and its types? Dielectrics […]
Is it OK to insulate interior walls?
Is it OK to insulate interior walls? Walls — both exterior and interior — are the next area to insulate in a home. Rigid boards work best on exterior walls, along with a vapor barrier. Fiberglass batts, foam or cellulose can be used to insulate the interior walls. The third area that needs proper insulation […]
What type of weather does a maritime polar air mass bring?
What type of weather does a maritime polar air mass bring? Maritime polar (mP): Cool and moist. They usually bring cloudy, damp weather to the USA. Maritime polar air masses form over the northern Atlantic and the northern Pacific oceans. They most often influence the Pacific Northwest and the Northeast. Where do air masses acquire […]
Do electric field lines go from positive to negative?
Do electric field lines go from positive to negative? Electric field lines always extend from a positively charged object to a negatively charged object, from a positively charged object to infinity, or from infinity to a negatively charged object. Electric field lines never cross each other. What is electric field and its formula? Electric field […]
Why is jet fuel cheaper than gasoline?
Why is jet fuel cheaper than gasoline? Lower Cost The good news is that kerosene is significantly cheaper than gasoline. Along with its lower freezing point, higher flash point and lower viscosity, this is one more reason why kerosene has become the preferred type of fuel in the aviation industry. Why is aviation fuel so […]
What is the best alternative to a colonoscopy?
What is the best alternative to a colonoscopy? The reimbursement for a sigmoidoscopy is also less than the cost to the doctor for doing the test. The final recommended test is CT colonography, sometimes called a virtual colonoscopy. It’s an X-ray procedure to inspect the colon. It too requires the same special diet and bowel […]
When a driver applies the brakes and her car slows down what happens to its kinetic energy?
When a driver applies the brakes and her car slows down what happens to its kinetic energy? When slowing down or stopping, your vehicle’s brakes must overcome its kinetic energy. It is important to realize that you are not simply working against speed, as the car’s kinetic energy will be four times as great as […]
What affects boiling point of water?
What affects boiling point of water? Atmospheric pressure influences the boiling point of water. When atmospheric pressure increases, the boiling point becomes higher, and when atmospheric pressure decreases (as it does when elevation increases), the boiling point becomes lower. Pressure on the surface of water tends to keep the water molecules contained. Can a tea […]
