Ahydrogen atom consists of a positively charged nucleus and a negatively charged electron. so, it is an electric dipole whose dipole moment is given by the product of the electron's charge and its distance from the nucleus. (a) calculate the expectation value of the dipole moment of a hydrogen atom in a stationary state vnlm in cartesian coordinates think about the physical implication of the result (b) for the state 211 calculate the expectation values of the squares of the cartesian components of the dipole moment, (d2), (d2), and (d2) you will need to express cartesian coordinates in terms of spherical polar ones, i. e r sin cos p and so on.

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.
