Describe how a friend with an external locus of control approaches a specific stressful situation. Identify how someone with an internal locus of control approaches a specific stressful situation. What are the consequences of these two different approaches for the two individuals described? What life experiences might have contributed to their external or internal approaches to their specific situations?

The nuclear potential that binds protons and neutrons in the nucleus of an atom is often approximated by a square well. imagine a proton conned in an innite square well of length 105 nm, a typical nuclear diameter. calculate the wavelength and energy associated with the photon that is emitted when the proton undergoes a transition from the rst excited state (n 2) to the ground state (n 1). in what region of the electromagnetic spectrum does this wavelength belong?
