What are the limitations of classical mechanics?
What are the limitations of classical mechanics? One experimental phenomenon that could not be adequately explained by classical physics was black-body radiation. Hot objects emit electromagnetic radiation. The burners on most electric stoves glow red at their highest setting. What are the inadequacy of classical mechanics? The inadequacy of Classical Mechanics are : It does […]
Is buoyant force always up?
Is buoyant force always up? The buoyancy force is caused by the pressure exerted by the fluid in which an object is immersed. The buoyancy force always points upwards because the pressure of a fluid increases with depth. What force is the opposite of buoyancy? Weight W acting vertically downwards works in the opposite direction […]

How does the ammeter work?
How does the ammeter work? Ammeters work to measure electrical current by measuring the current through a set of coils with a very low resistance and inductive reactance. If the ammeter were connected in parallel, the path may become short-circuited such that all the current will flow through the ammeter instead of the circuit. What […]
Is there an organism without DNA?
Is there an organism without DNA? All the self‐reproducing cellular organisms on the Earth so far examined have DNA as the genome, and the informational flow from DNA to RNA to protein is the basis of their biological function (Alberts et al. 2008). Based on this fact, almost all the biologists must think that there […]
