The debye theory, as given in this chapter, was worked out before it was known that a harmonic oscillator has a "zero-point energy" of hv/2. thus eq. (20) does not give the correct total energy of a solid in the limit t-0, because the average energy per oscillator goes to hv/2, rather than zero, at t 0. starting with this fact, use the debye model to show that the zero-point energy of a solid should be er.

the cellphone, they would then know if the killer would have contacted them or always hated them. or if it was a breakup. but if that is not the case, then it would be the clothing. to put in a bullet, it would have to be put in by hands. hands have finger prints which, would have giving you the answer of who done it.
