Here is a question about this article: The Reconquista of Portugal and Spain led to a series of oceanic explorations resulting in the Age of Discovery that established direct links with Africa, the Americas, and Asia, while religious wars continued to be fought in Europe, which ended in 1648 with the Peace of Westphalia. The Spanish crown maintained its hegemony in Europe and was the leading power on the continent until the signing of the Treaty of the Pyrenees, which ended a conflict between Spain and France that had begun during the Thirty Years' War. An unprecedented series of major wars and political revolutions took place around Europe and indeed the world in the period between 1610 and 1700. Observers at the time, and many historians since, have argued that wars caused the revolutions. Galileo Galilei, invented the telescope and the thermometer which allowed him to observe and describe the solar system. Leonardo da Vinci painted the most famous work in the world. Guglielmo Marconi invented the radio.
What is the answer to this question: Which scientist developed a means of viewing space?
****
So... Galileo Galilei


Here is a question about this article: A wide array of sports are played in Armenia, the most popular among them being wrestling, weightlifting, judo, association football, chess, and boxing. Armenia's mountainous terrain provides great opportunities for the practice of sports like skiing and climbing. Being a landlocked country, water sports can only be practiced on lakes, notably Lake Sevan. Competitively, Armenia has been successful in chess, weightlifting and wrestling at the international level. Armenia is also an active member of the international sports community, with full membership in the Union of European Football Associations (UEFA) and International Ice Hockey Federation (IIHF). It also hosts the Pan-Armenian Games.
What is the answer to this question: Which lake is most popular for water sports in Armenia?
****
So... Lake Sevan


Here is a question about this article: 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 the answer to this question: In what type of applications is piezeoelectricity especially problematic?

So...
audio applications
