An operator p describing the interaction of two spin are constants and σ1 and σ2 are pauli spin matrices of the two spins. the total spin angular 20. particles is p-a + b σ io, where a and b momentum s-s1 + s2-2 h (o, + ơ2). show that p, st and s, can be measured simultaneously.

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.
