Consider the particle in a one-dimensional box (0sx s l). assume a term is added to the hamiltonian of the form: v(x)=-g sn(x) tx sketch the potential and the expected eigenfunction (small g). in the limit of small g, find the second order correction to the ground state energy

Laboratory experiments, observational field studies, and model-building are all examples of different forms of scientific investigations.  in what way do laboratory experiments primarily differ from other forms of scientific investigations?   a.  a laboratory experiment is the only accepted form of investigation within the scientific community.  b.  studies about how things behave in nature or studies involving very large objects are best answered through laboratory experiments.  c.  laboratory experiments involve the identification and control of variables.  d.  data can only be generated through laboratory experiments, not other forms of investigation.
