Explanation According to Archimedes’ principle, any object immersed wholly or partially in a fluid it experiences a force which is equal in magnitude to the weight of the volume of fluid that the object displaces. Force of buoyancy is the upward force that results when an object is fully or partially immersed in a fluid. The force of buoyancy is obtained from Archimedes’ principle. The object will sink or float in fluid depends on the density of object ρ o relative to density of fluid ρ f . Here, the fluid medium is air and object is helium balloon. The object will float in fluid if the average density of the object is less than the density of fluid

Debye Theory of Solids

In solid-state physics, debye theory is used to estimate the phonons contributing to the specific heat capacity in a solid. It explains that the specific heat is a consequence of the vibrations of the atomic lattice of the solid, which is in contrast to …
