2.11 4.3×107 J.
2.12 n0 = 2.69 ×1025 molecules m−3, H = 8000 m, N =2.15×1029 molecules.
2.13 zλ=H = H ln(n0σcH).
2.14 (gp0/RT0) ∫∞0ze−z/H dz = gp0H2/RT0.
2.15 ½ Nm0v2 =32; NkBT, see Problem 2.12 for N.
2.16 fyellow = c/λ = 6.0 × 1014 s−1. fcoll = n0σc≈ 6.5 × 109 s−1. An excited atom might suffer tens of collisions before it relaxes to the lower energy level.
