If an electron is in an excited state, it must lose energy when it falls to a lower state. What happens to the energy that is lost? A. It is released as a neutron.
B. It is released as a photon of light.
C. It is stored in the nucleus of the atom.
D. It is released as a stream of electrons.

The dissociation energy of a molecule is the energy required tobreak apart the molecule into its separate atoms. the dissociationenergy for a particular molecule is 5.48 x 10-18 j.suppose that this energy is provided by a single photon. determinethe (a) wavelength and (b) frequency of the photon

In a load, the load is paralel to the shaft. n a. angular n b. thrust n c radial n d. none of the above

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)
