Is it possible for a solid metal ball to float in mercury? Is it possible for a solid metal ball to float in mercury? No, the mass of the solid metal ball is greater than that of the mercury so it will not float. Why the ships can float on the sea but a small […]
How many different alcohol types are there?
How many different alcohol types are there? four types What is the 3 types of alcohol? The three kinds of alcohols are primary, secondary and tertiary. What is the most sophisticated alcohol? Cognac Is Negroni a man’s drink? This is a real bartenders’ drink. Many will say it is a man’s drink but I think […]
Which particle is not affected by a magnetic field?
Which particle is not affected by a magnetic field? gamma radiation When a soap bubble is given? When charge is given to a soap bubble (whether positive or negative), these charges exerience repuisive forces due to the other charges. Hence they tend to move out. Hence the size of bubble increases. What is the effect […]
What happens to kinetic energy when momentum is doubled?
What happens to kinetic energy when momentum is doubled? Kinetic energy is directly proportional to the squared of the velocity. This means that when momentum is doubled, mass remaining constant, velocity is doubled, as a result now kinetic energy becomes four times greater than the original value. Are momentum and kinetic energy the same? They […]
Can the Great Wall of China be seen from space?
Can the Great Wall of China be seen from space? The Great Wall of China, frequently billed as the only man-made object visible from space, generally isn’t, at least to the unaided eye in low Earth orbit. It certainly isn’t visible from the Moon. You can, though, see a lot of other results of human […]
Why can a magnet attract an Unmagnetized nail?
Why can a magnet attract an Unmagnetized nail? Stroking material containing iron with a magnet, placing a piece of iron in the strong magnetic field, placing a piece of iron near a strong electromagnet. The reason a magnet can attract an unmagnetized nails is that? nails become temporarily magnetized in a magnetic field. Why can’t […]
Why do electrons move freely in metals?
Why do electrons move freely in metals? The valence electrons of metals move freely in this way because metals have relatively low electronegativity, or attraction to electrons. The positive metal ions form a lattice-like structure held together by all the metallic bonds. When nonmetals bond together, the atoms share valence electrons and do not become […]
What is the process of pressing sediments?
What is the process of pressing sediments? COMPACTION. The process by which sediments are pressed together under their own weight. CEMENTATION. The process by which dissolved minerals crystallize and glue particles of sediment together into one mass. What evidence do you see that sediments are being transported? Sedimentsare small rock fragments such as sand or […]
What is the principle of Maldi-Tof?
What is the principle of Maldi-Tof? MALDI is the abbreviation for “Matrix Assisted Laser Desorption/Ionization.” The sample for MALDI is uniformly mixed in a large quantity of matrix. The matrix absorbs the ultraviolet light (nitrogen laser light, wavelength 337 nm) and converts it to heat energy. What is the role of Reflectron in Maldi-Tof? A […]
