Consider an Einstein solid in the low-temperature limit N ≫ q ≫ 1, which has the multiplicity Ω = ( eN q )q (a) Find a formula for the temperature of an Einstein solid in the limit q ≪ N. Let U = qε where ε is the energy per quantum. (b) Solve for the energy as a function of temperature to obtain U = Nεe−ε/kT . What is limT→0 U?

Julia would be observing a. static electricity was caused by her sweater rubbing against her shirt and transferring electrons. she didn't touch anything metal, so that would cancel out b.she most likely didn't rub her sweater against her hair either, so that cancels out c.she also didn't scoot across the carpet while trying to take her sweater off, that cancels out d.so that leaves a.a. is correct.

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
