2gases are mixed into an adiabatic and mechanically rigid container (no exchange of heat or energy through the walls) and exit through an exhaust stream (3). mass, momentum, and energy exchance can take place within the mixer. gas 1 has properties of stagnation pressure p01, stagnation temperature t01, and mass flow rate m1'. gas 2 has properties p02, t02, and mass flow rate m2' = a*m1'. the specific heat ratios are the same and remain constant. derive an equation for maximum stagnation pressure p03and temperature t03that can be acheived in the mixed airstream.

The correct choice is c

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
