[Q]: 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.
[A]: Science

[Q]: In the Corey-Bakshi-Shibata catalyst, an atom of it is attached to a pyrrole ring, an oxygen atom, and a toluene group. This element's acids are combined with amines and ketones in the Petasis reaction and in combining alkyl halides through the Suzuki coupling. Complexes containing it are called sido or arachno according to Wade's rules, and a more famous reaction using it is sometimes named for Herbert Brown. Mined from the ore Uletite, its silicate was once used in making hard glass for manufacturing laboratory equipment. For 10 points, name this element that participates in an anti-markonikov addition reaction to alkenes, with atomic number 5 and symbol B.
[A]: Science

[Q]: This composer wrote a ballet about seven buffoons who kill their wives after a mysterious man tells them he will bring them back to life with a magic whip. This composer of The Steel Step and Chout wrote the score for a ballet that includes an intense duet with "the Siren" based on a parable from the gospel of Luke. Another ballet's third act centers around three galops performed by the Prince before he recognizes the title character. In addition to The Prodigal Son, he composed a ballet featuring the "Dance of the Knights" and a famous dance by Queen Mab whose first act "Gavotte" is based on a theme from his Classical Symphony. For 10 points, name this Russian composer who wrote the ballets Cinderella and Romeo and Juliet, as well as Peter and the Wolf.
