An anharmonic oscillator exploiting this effect as a microelectromechanical system component was proposed by Serry, Walliser, and Maclay. Julian Schwinger has postulated that sonoluminescence arises due to this effect, and this effect requires that bag radius and mass are independent under a combination of the Skyrmion and MIT models, the chiral bag model of the nucleon. One setup for measuring it attached a polystyrene sphere to an atomic force microscope, and Lamoreaux used a torsional pendulum to achieve the first precise measurements of this effect. This force may produce pressures as large as an atmosphere at a separation of ten nanometers. For 10 points, name this effect arising from zero-point energy, described by the attraction or repulsion due to virtual photons between two close uncharged metallic sheets in a vacuum.

title character of one of his operas sings of being a ruler in "Del pi sublime soglio", which sees Vitellia sing of her anger and grief in "Deh se piacer" and "Non pi di fiori. " For 10 points each: [10] Name this composer of La Clemenza di Tito and Il Re Pastore, both works with libretto by Metastasio.

This equation can be generalized to a simplification of the Tafel equation when in the high overpotential region. That equation is called the Butler-Volmer equation; another generalization of this equation describes the equilibrium potential across a cell's membrane using all the ions that pass through and is named after [*] Goldman. In this equation, the ideal gas constant is multiplied by temperature and divided by the moles of electrons and the Faraday constant, and that ratio is multiplied by the natural log of Q. For 10 points, name this equation from electrochemistry which calculates the reduction potential of a cell, named after a German chemist.
