What happens when a warm and cold air mass collide? When a warm air mass meets a cold air mass, the warm air rises since it is lighter. As it rises, the warm air cools rapidly. This configuration, called a cold front, gives rise to cumulonimbus clouds, often associated with heavy precipitation and storms. What […]
What reduces cholesterol quickly?
What reduces cholesterol quickly? A few changes in your diet can reduce cholesterol and improve your heart health: Reduce saturated fats. Saturated fats, found primarily in red meat and full-fat dairy products, raise your total cholesterol. Eliminate trans fats. Eat foods rich in omega-3 fatty acids. Increase soluble fiber. Add whey protein. Can you live […]
What is a good analogy?
What is a good analogy? A good analogy is a compromise between two conflicting goals: familiarity and representativeness. Good analogies are familiar. They express an abstract idea in terms of a familiar one. But a good analogy doesn’t need to be concrete, it only needs to be expressed in terms of an idea you already […]
Is eccentricity positive or negative?
Is eccentricity positive or negative? In mathematics, the eccentricity of a conic section is a non-negative real number that uniquely characterizes its shape. How is eccentricity calculated? The formula to determine the eccentricity of an ellipse is the distance between foci divided by the length of the major axis. What does a negative eccentricity mean? […]
What is the relation between refractive index and intensity?
What is the relation between refractive index and intensity? The intensity of light (as calculated from time average of the poynting vector) is given by I=(1/2)ϵvE20. Here the intensity is dependent on the velocity of light in the medium. The refractive index also depends on the velocity of light. What is the speed and intensity […]
How does oxygen turn into ion?
How does oxygen turn into ion? Oxygen, O. Oxygen is in Group 6. It has six electrons in its outer shell. It gains two electrons from one or two other atoms in reactions, forming an oxide ion, O 2-. Can oxygen ion be positive? Thus, an energetic electron passing near or through an oxygen molecule, […]
At what temperature does all motion cease theoretically?
At what temperature does all motion cease theoretically? A temperature scale whose zero point is absolute zero, the temperature of 0 entropy at which all molecular motion stops, -273.15° C. The size of a degree Kelvin is the same as the size of a degree Celsius. Which temperature does all molecular motion steps? Step by […]
How can you tell if MAP sensor is bad?
How can you tell if MAP sensor is bad? What to look out for in a failing MAP sensor Rich air-fuel ratio: Look for rough idle, poor fuel economy, slow acceleration and a strong smell of gasoline (especially at idle) Lean air-fuel ratio: Look for surging, stalling, lack of power, hesitation on acceleration, backfiring through […]
Does Heat travel up or down?
Does Heat travel up or down? “Heat” does not travel up. Heat can travel in all directions. The direction heat travels depends on the specifics of a system not in thermal equilibrium. In contrast, “hot air” on earth’s surface tends to go up. What material reflects the most heat? Note that a metal will only […]
Where are the inner transition elements?
Where are the inner transition elements? The inner transition metals are found in the f-block, usually put at the bottom of the Periodic Table. These elements were sometimes called rare earth metals due to their extremely low natural occurrence. What are transition metals and their properties? The transition metals have the following physical properties in […]
