5. An artist constructs a mobile that is suspended from the ceiling using a cable. Three shapes are hanging from a beam at the locations shown below. The mass of the star is 10 kg, the mass of the sun is 5 kg and the mass of the beam is 2 kg. What is the mass of the moon if the mobile is in static equilibrium? (Give your answer in kg.)

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.
