Capacitors, especially ceramic capacitors, and older designs such as paper capacitors, can absorb sound waves resulting in a microphonic effect. Vibration moves the plates, causing the capacitance to vary, in turn inducing AC current. Some dielectrics also generate piezoelectricity. The resulting interference is especially problematic in audio applications, potentially causing feedback or unintended recording. In the reverse microphonic effect, the varying electric field between the capacitor plates exerts a physical force, moving them as a speaker. This can generate audible sound, but drains energy and stresses the dielectric and the electrolyte, if any.
What is it called when a changing electric field existing between the conductive plates of a capacitor physically moves them?
A: the reverse microphonic effect

After World War I, when Britain and France divided up the Middle East's countries, apart from Turkey, between them, pursuant to the Sykes-Picot agreementin violation of solemn wartime promises of postwar Arab autonomythere came an immediate reaction: the Muslim Brotherhood emerged in Egypt, the House of Saud took over the Hijaz, and regimes led by army officers came to power in Iran and Turkey. "[B]oth illiberal currents of the modern Middle East," writes de Bellaigne, "Islamism and militarism, received a major impetus from Western empire-builders." As often happens in countries undergoing social crisis, the aspirations of the Muslim world's translators and modernizers, such as Muhammad Abduh, largely had to yield to retrograde currents.
What was the dividing up of the Middle Eastern countries in violation of?
A: solemn wartime promises of postwar Arab autonomy

The main mode of transportation, however, relies on Seattle's streets, which are laid out in a cardinal directions grid pattern, except in the central business district where early city leaders Arthur Denny and Carson Boren insisted on orienting their plats relative to the shoreline rather than to true North. Only two roads, Interstate 5 and State Route 99 (both limited-access highways), run uninterrupted through the city from north to south. State Route 99 runs through downtown Seattle on the Alaskan Way Viaduct, which was built in 1953. However, due to damage sustained during the 2001 Nisqually earthquake the viaduct will be replaced by a tunnel. The 2-mile (3.2 km) Alaskan Way Viaduct replacement tunnel was originally scheduled to be completed in December 2015 at a cost of US$4.25 billion. Unfortunately, due to issues with the worlds largest tunnel boring machine (TBM), which is nicknamed "Bertha" and is 57 feet (17 m) in diameter, the projected date of completion has been pushed back to 2017. Seattle has the 8th worst traffic congestion of all American cities, and is 10th among all North American cities.
What is mainly used for transportation in Seattle?
A: streets

The first documented visit by a European was in 1524 by Giovanni da Verrazzano, a Florentine explorer in the service of the French crown, who sailed his ship La Dauphine into New York Harbor. He claimed the area for France and named it "Nouvelle Angouleme" (New Angouleme).
What nation did Giovanni da Verrazzano serve?
A:
France
