Consider a two-dimensional hexagonal lattice: (a) Draw the free electron Fermi surface in the reduced zone scheme when the lattice points are occupied by atoms with: i. One valence electron/atom. ii. Two valence electrons/atom.

Below is a energy level scheme of a hypothetical one- electron element Mathematicum.

Below is a energy level scheme of a hypothetical one- electron element Mathematicum. The potential energy is taken to be zero for an electron at an infinite distance from the nucleus. (a) (15) How much energy does it take to ionize an electron from the first excited level (n = 2) ? (b) (4) An 8-eV photon is absorbed by a Mathematicum atom in its first excited level. As the atom returns to the first excited level, what possible...

Question Using the AD-AS model, show and discuss how uncertain labour market conditions (reduced working hours, possible layoffs, length of employment, etc.) due to COVID-19 pandemic will affect output and prices in the short-run. Note: Maximum of one page to be submitted in PDF format via dropbox. On average, I expect 5-8 lines of concise explanations and a simple diagram. Please use MS word to draw the diagram. Click on Insert, then shapes.
