Does elastic potential energy depend on mass? Kinetic energy depends on an object’s mass and velocity. Potential energy is the energy stored in an object because of its position or shape. It includes gravitational potential energy and elastic potential energy. Gravitational potential energy depends on an object’s weight and height above the ground. Is momentum […]

Is potential defined for induced electric field? This means we can not define a electrostatic potential corresponding to this field. Hence this electric field produced by changing electric field is non electrostatics and non-conservative in nature. We call such a field as induced electric field. Which of the following statement is not characteristics of a […]

Which of the following has least packing fraction? Simple cubic unit cell has least packing efficiency that is 52.4%. Which of the following has the most effective packing fraction in 3d space? packing efficiencies are : simple cubic = 52.4% , Body – centred cubic = 68% , Hexagonal close-packed = 74 % thus, hexagonal […]

Does a fish pee? Like you, fish have kidneys. Kidneys help the body make urine. A lot of fish get rid of the pee through an tiny opening, called a pore, that’s near their rear ends—and in some fish, waste also goes out through the skin or the gills. Do fish eat their poop? Do […]

Can eye glasses be used to start a fire? How to Start a Fire with Glasses. In a pinch, you can start a fire using reading glasses or prescription glasses instead of a magnifying glass. If you’re lucky, you can just focus the sun through one lens of the glasses. If you’re not so lucky, […]

What does green light mean in a dream? The color light green in a dream represents healing. When you see it in a dream it reflects the removal of obstacles, or positive change. Light green may also be a sign that you are experiencing physical healing. Alternatively, lighter shades of green may also reflect jealousy, […]

Why is a magnet strongest at its pole? the magnetic field lines never cross each other. the closer the lines, the stronger the magnetic field (so the magnetic field from a bar magnet is strongest closest to the poles) Can ever there be a magnet without pole? There is never an isolated pole (a monopole). […]

What is a prokaryotic and eukaryotic cell? Prokaryotes are organisms that consist of a single prokaryotic cell. Eukaryotic cells are found in plants, animals, fungi, and protists. They range from 10–100 μm in diameter, and their DNA is contained within a membrane-bound nucleus. Eukaryotes are organisms containing eukaryotic cells. What is in a prokaryotic cell? […]

What is another word for organelle? Synonyms for Organelle: cell wall, chloroplast, culture medium, culture, cytology, cellular, cell membrane, cell. What is the definition of cell organelles? An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the […]

Can I reuse piston rings after honing? Ity should be emphasized that the “right” way to do this is to bore the engine and replace the pistons and rings, and that if the old rings are still working, it’s best to reuse them, as they’re mated to the cylinders already, but if you have to […]
