The ground-state wavefunction of a certain molecule is described by the vibrational wavefunction:
= −ax^2 .
calculate the franck–condon factor for a transition to a vibrational state described by the wavefunction:
′=−−x0)^2/2 .

The filament of an incandescent lamp has a temperature of 2000k. calculate the fraction of radiation emitted in the visible light band if the filament is approximated as blackbody

Steam enters a converging nozzle at 3.0 mpa and 500°c with a at 1.8 mpa. for a nozzle exit area of 32 cm2, determine the exit velocity, mass flow rate, and exit mach number if the nozzle: negligible velocity, and it exits (a) is isentropic (b) has an efficiency of 94 percent
