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 the Einstein model. In the Einstein model, solids are treated as independent, non-interacting quantum harmonic oscillators. This model clearly explains the low-temperature dependence of the heat capacity, which is proportional to T3. This is known as Debye T3 law.

A B Let's revisit a previous problem and add the force of friction. In the figure, block A has a mass of 2.67 kg. It rests on a smooth but not frictionless horizontal table and is connected by a very light horizontal string over an ideal pulley to block B, which has a mass of 3.28 kg. The coefficient of kinetic friction between block A and the table is 0.2. When block B is gently released from rest, how long does it take block B to travel 0.983 m? Note: Be careful! Be sure all quantities are expressed in standard units before calculating anything. Report your answer in seconds.
