Why can electric field lines never cross?

Why can electric field lines never cross? Electric field lines cannot cross. This is because they are, by definition, a line of constant potential. The equipotential at a given point in space can only have a single value. If lines for two different values of the potential were to cross, then they would no longer […]

What source of energy does the body use first?

What source of energy does the body use first? Carbohydrates are the main energy source of the human diet. The metabolic disposal of dietary carbohydrates is direct oxidation in various tissues, glycogen synthesis (in liver and muscles), and hepatic de novo lipogenesis. What are the main sources of energy body? Carbohydrates, such as sugar and […]

What are the 4 components of an atom?

What are the 4 components of an atom? The parts of an atom are protons, electrons, and neutrons. A proton is positively charged and is located in the center or nucleus of the atom. Electrons are negatively charged and are located in rings or orbits spinning around the nucleus. The number of protons and electrons […]

What is the formula for FG?

What is the formula for FG? The “gravity” on the surface of a planet is it’s acceleration (the rate of increase in speed as an object falls). Fg (the force of gravity) is m x g (acceleration of gravity), in m/(s squared), so g is Fg / m = 123 N / 25 kg ~= […]

What recommendations do the Dietary Guidelines for Americans 2015 2020 make in regards to sugar consumption?

What recommendations do the Dietary Guidelines for Americans 2015 2020 make in regards to sugar consumption? The 2015-2020 Dietary Guidelines for Americans recommends limiting calories from added sugars to no more than 10% each day. That’s 200 calories, or about 12 teaspoons, for a 2,000 calorie diet. What is new in the 2020-2025 Dietary Guidelines? […]

How do you calculate time difference between numbers?

How do you calculate time difference between numbers? Time difference in hours as decimal value Generic formula. =MOD(end-start,1)*24. Summary. To get the duration between two times in as decimal hour (i.e. 3 hrs, 4.5 hrs, 8 hrs, etc.) you can use a formula based on the MOD function. Excel dates are serial numbers, and a […]

What happens when gas volume increases?

What happens when gas volume increases? If the amount of gas in a container is increased, the volume increases. If the amount of gas in a container is decreased, the volume decreases. Gay Lussac’s Law – states that the pressure of a given amount of gas held at constant volume is directly proportional to the […]

Why is potential energy U?

Why is potential energy U? U is the letter most similar to V – there are lots of times when, if V is used as a variable for a concept, then U is a variable for a similar concept. So potential energy became U, because someone might have been trying to make a connection with […]

What is the warmest layer of the atmosphere?

What is the warmest layer of the atmosphere? The thermosphere is often considered the “hot layer” because it contains the warmest temperatures in the atmosphere. What flew in the thermosphere before it was grounded? E. The thermosphere contains a layer of charged particles called the ionospherewhich makes communication by radio wavespossible and is home to […]
