Is the lithosphere below the asthenosphere? The lithosphere is the solid, outer part of the Earth. It includes the brittle upper portion of the mantle and the crust, the planet’s outermost layers. The lithosphere is located below the atmosphere and above the asthenosphere. What is the Plasticlike layer below the lithosphere? The plasticlike layer below […]
What happens when a refrigerant vapor is compressed?
What happens when a refrigerant vapor is compressed? Vapor-compression uses a circulating liquid refrigerant as the medium which absorbs and removes heat from the space to be cooled and subsequently rejects that heat elsewhere. How does cooling occur in a direct expansion vapor compression refrigeration system? The compressor takes in a low temperature, low pressure […]
Which best describes the relationship between brightness B and distance d )?
Which best describes the relationship between brightness B and distance d )? Inverse Square Law of Brightness The Apparent Brightness (B) of a source is inversely proportional to the square of its distance (d): Implications: It will appear 22=4 times brighter. Which type of dwarf is largest? A typical white dwarf is about as massive […]
What do you mean by C * * * * * * * * * Frequency?
What increases when frequency increases?
What increases when frequency increases? From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer. There are two basic types of waves: mechanical and electromagnetic. What is the highest frequency ever generated? At least ~100 GeV, which corresponds to 2*1025 Hz. I […]
How long do rechargeable batteries last if not used?
Is acetone the same as hydrogen peroxide?
Is cooking a chemical change?
Is cooking a chemical change? Rotting, burning, cooking, and rusting are all further types of chemical changes because they produce substances that are entirely new chemical compounds. For example, burned wood becomes ash, carbon dioxide, and water. An unexpected color change or release of odor also often indicates a chemical change. What type of chemical […]
What elements have the smallest atomic radius?
What elements have the smallest atomic radius? Explanation: Helium has the smallest atomic radius. Which element has the largest atomic radius K or Na? As an example, potassium (K) has a larger average atomic radius (220 pm)than sodium (Na) does (180 pm). The potassium atom has an extra electron shell compared to the sodium atom, […]
