What is the result of polarization of dielectric material? Because of dielectric polarization, positive charges are displaced in the direction of the field and negative charges shift in the direction opposite to the field (for example, if the field is moving in the positive x-axis, the negative charges will shift in the negative x-axis). What […]

How do our bodies release the energy stored in food? When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose. The stomach and small intestines absorb the glucose and then release it into the bloodstream. How is energy in ATP released? In a […]

How far ahead should you look in your path? In a suburban area, you should look at least three blocks or three traffic signals ahead. In a rural area, you should look at least a quarter of a mile ahead. When looking well ahead, look for vehicles coming onto the roadway, into your lane, or […]

What is a service and its characteristics? The defining characteristics of a service are: Intangibility: Services are intangible and do not have a physical existence. Hence services cannot be touched, held, tasted or smelt. This is most defining feature of a service and that which primarily differentiates it from a product. What are the main […]

How dangerous is driving really? But driving is likely the most dangerous thing you ever do, and most of us are in a car nearly every day! Each day, another 3,000 lives are lost due to motor vehicle accidents. That comes out to more than 1,000,000 traffic accident deaths every single year. What are some […]

What is the main component of soil? Soil Layers. Soil is composed of both biotic—living and once-living things, like plants and insects—and abiotic materials—nonliving factors, like minerals, water, and air. Soil contains air, water, and minerals as well as plant and animal matter, both living and dead. These soil components fall into two categories. What […]

What are the six properties of ionic compounds? Properties Shared by Ionic Compounds They form crystals. They have high melting points and high boiling points. They have higher enthalpies of fusion and vaporization than molecular compounds. They’re hard and brittle. They conduct electricity when they are dissolved in water. They’re good insulators. Why are covalent […]

How far north does the Gulf Stream go? The Gulf Stream stretches 40 to 50 miles wide off the coast of southeast Florida as it chugs and snakes, ultimately toward Iceland, at a clip of 2 to 4 miles per hour. How fast is the current in the Gulf Stream? about 5.6 miles per hour […]

Is it possible to have a zero electric field value? 7) Is it possible to have a zero electric field value between a negative and positive charge along the line joining the two charges? Yes, regardless of the magnitude of the two charges. C) No, a zero electric field cannot exist between the two charges. […]

What is type of hazard? physical – radiation, magnetic fields, pressure extremes (high pressure or vacuum), noise, etc., psychosocial – stress, violence, etc., safety – slipping/tripping hazards, inappropriate machine guarding, equipment malfunctions or breakdowns. What are 4 types of physical hazards? Physical hazards include ergonomic hazards, radiation, heat and cold stress, vibration hazards, and noise […]
