Round 100: Tossup 2

Claude Pouillet inspired the setup of this non-Italian scientist’s pioneering experiment to measure the speed of nerve impulses in the sciatic nerve of frog legs. The integral form of the Schrödinger equation can be obtained using the Green’s function of this scientist’s namesake equation, which equals “e to the ikr over r.” This scientist invented a device made of two wire loops with equal radius and separation, which creates (-5[1])a near-uniform (*) magnetic field. (10[1])The wave equation (10[1])for the electric field reduces to this scientist’s namesake equation, which states “del squared f plus k squared f equals zero.” A quantity named for this scientist equals minus kT times log Z, or U minus TS. For 10 points, the useful work that can be extracted (10[2])at constant temperature and volume is what German scientist’s “free energy”? ■END■ (0[1])
