일반물리학 2 — Relativity: Problem 34

34 (a) The energy released in the explosion of 1.00 mol of TNT is 3.40 MJ. The molar mass of TNT is 0.227 kg/mol. What weight of TNT is needed for an explosive release of \(2.50 \times 10^{14}\) J? (b) Can you carry that weight in a backpack, or is a truck or train required? (c) Suppose that in an explosion of a fission bomb, 0.080% of the fissionable mass is converted to released energy. What weight of fissionable material is needed for an explosive release of \(2.50 \times 10^{14}\) J? (d) Can you carry that weight in a backpack, or is a truck or train required?
