What is one drawback of government intervention in international trade? Intervention can be dangerous and can trigger a trade war. Intervention can lead to the dispersion of production activities. Intervention ultimately closes all markets to foreign competition. Intervention is not welcome in the agricultural sector. Intervention tends to protect the efficient firm rather than the inefficient firm, which results in higher prices.

LP 3. (10 pts) A new, one electron element is discovered from the analysis of moose nuggets, and it is called Moosonium. The potential energy between the electron and the nucleus is unknown, but the energy-level scheme for the element is measured and is shown in the figure at right. The potential energy is taken to be zero for an electron at an infinite distance from the nucleus. a) How much energy (in eV) does it take to ionize an electron from the ground level? b) A 28 eV photon is absorbed by a Moosonium atom in its ground state. As the atom returns to its ground level, what possible energies can the emitted photon have? c) What will happen if a photon with an energy of 14 eV strikes a Moosonium atom in it ground state? d) Photons emitted in the Moosonium transition $n=3 \rightarrow n = 2$, and also in the transition $n = 3 \rightarrow n = 1$, will eject photoelectrons from an unknown metal, but the photon emitted from the transition $n = 4 \rightarrow n$ $= 3$ will not. What is the range of possible values for the work function of the metal?
