What is the difference between model and approach? As nouns the difference between model and approach is that model is a person who serves as a subject for artwork or fashion, usually in the medium of photography but also for painting or drawing while approach is the act of drawing near; a coming or advancing […]
Why are top predators so rare?
Why are top predators so rare? This energy constraint is the fundamental reason top predators are so rare. Many food webs consist of half a dozen or more trophic levels, and by the time you get to the top, there’s simply not that much energy left. It’s their naturally small populations that also leave these […]
What happens to pressure if volume decreases in gas?
What happens to pressure if volume decreases in gas? Explanation: Gas particles exert pressure by colliding with the walls of their container. If you reduce the volume, you are effectively increasing the density of the particles and they will collide with the walls more frequently, leading to an increase in pressure. Why does the volume […]
What is a food chain in an ecosystem?
What is a food chain in an ecosystem? A food chain describes how energy and nutrients move through an ecosystem. In the food chain, energy is transferred from one living organism through another in the form of food. There are primary producers, primary consumers, secondary consumers and decomposers- all part of the food chain. How […]
What is the coating on the inside of a light bulb?
What is the coating on the inside of a light bulb? The white powder coating inside the glass tubing of a CFL contains a fluorescent coating. When electricity enters a CFL, mercury and argon fumes inside the bulb produce invisible ultraviolet (UV) light. This UV light reacts with the fluorescent coating to produce the white, […]
Is Shiva linga a male organ?
Is Shiva linga a male organ? According to Sivaya Subramuniyaswami, the lingam signifies three perfections of Shiva. According to Rohit Dasgupta, the lingam symbolizes Shiva in Hinduism, and it is also a phallic symbol. Since the 19th-century, states Dasgupta, the popular literature has represented the lingam as the male sex organ. Is Shiva male or […]

The most abundant or easily synthesized actinides are uranium and thorium, followed by plutonium, americium, actinium, protactinium, neptunium, and curium. What is the lightest actinide? Protactinium What do you call the element from atomic […]
What is the ideal gas thermometer?
What is the ideal gas thermometer? In principle, we can measure the same temperature using any gas, so long as the constant operating pressure is low enough. When we do so, our device is called the ideal gas thermometer. The (very nearly) direct proportionality of two low-pressure real gas volumes contrasts with what we observe […]
Are linear and angular momentum conserved separately?
Are linear and angular momentum conserved separately? Now, such an object can be assumed to have a constant mechanical energy. But that is only one part of the story. The fact is, since each linear and angular momentum of this object is conserved, the respective components of its linear and angular energy also would be […]
What temperature should I wash white bed sheets on?
What temperature should I wash white bed sheets on? Use the hottest water setting on your washing machine that’s safe for the material. Polyester blends are best washed using warm water, while cotton can tolerate hot water. Hotter water kills the most germs and takes care of dust mites that thrive in bedding. How long […]
