Question: Leakage is equivalent to a resistor in parallel with the capacitor. Constant exposure to heat can cause dielectric breakdown and excessive leakage, a problem often seen in older vacuum tube circuits, particularly where oiled paper and foil capacitors were used. In many vacuum tube circuits, interstage coupling capacitors are used to conduct a varying signal from the plate of one tube to the grid circuit of the next stage. A leaky capacitor can cause the grid circuit voltage to be raised from its normal bias setting, causing excessive current or signal distortion in the downstream tube. In power amplifiers this can cause the plates to glow red, or current limiting resistors to overheat, even fail. Similar considerations apply to component fabricated solid-state (transistor) amplifiers, but owing to lower heat production and the use of modern polyester dielectric barriers this once-common problem has become relatively rare.
Is there an answer to this question:  What will never cause excessive leakage in a capacitor?

Answer: unanswerable


Question: In addition to the use of sound for communication, a wide range of insects have evolved chemical means for communication. These chemicals, termed semiochemicals, are often derived from plant metabolites include those meant to attract, repel and provide other kinds of information. Pheromones, a type of semiochemical, are used for attracting mates of the opposite sex, for aggregating conspecific individuals of both sexes, for deterring other individuals from approaching, to mark a trail, and to trigger aggression in nearby individuals. Allomonea benefit their producer by the effect they have upon the receiver. Kairomones benefit their receiver instead of their producer. Synomones benefit the producer and the receiver. While some chemicals are targeted at individuals of the same species, others are used for communication across species. The use of scents is especially well known to have developed in social insects.:96–105
Is there an answer to this question: What insect chemical benefits both the receiver and the producer?

Answer: Synomones


Question: Fraser maintained some of the social reforms of the Whitlam era, while seeking increased fiscal restraint. His government included the first Aboriginal federal parliamentarian, Neville Bonner, and in 1976, Parliament passed the Aboriginal Land Rights Act 1976, which, while limited to the Northern Territory, affirmed "inalienable" freehold title to some traditional lands. Fraser established the multicultural broadcaster SBS, accepted Vietnamese refugees, opposed minority white rule in Apartheid South Africa and Rhodesia and opposed Soviet expansionism. A significant program of economic reform however was not pursued. By 1983, the Australian economy was suffering with the early 1980s recession and amidst the effects of a severe drought. Fraser had promoted "states' rights" and his government refused to use Commonwealth powers to stop the construction of the Franklin Dam in Tasmania in 1982. Liberal minister, Don Chipp split off from the party to form a new social liberal party, the Australian Democrats in 1977. Fraser won further substantial majorities at the 1977 and 1980 elections, before losing to the Bob Hawke led Australian Labor Party in the 1983 election.
Is there an answer to this question: Who did Frazer eventually lose to in 1976?

Answer: unanswerable


Question: Valencia is a bilingual city: Valencian and Spanish are the two official languages. Spanish is official in all of Spain, whereas Valencian is official in the Valencian Country, as well as in Catalonia and the Balearic Islands, where it receives the name of Catalan. Despite the differentiated denomination, the distinct dialectal traits and political tension between Catalonia and the Valencian Country, Catalan and Valencian are mutually intelligible and are considered two varieties of the same language.
Valencian has been historically repressed in favour of Spanish. The effects have been more noticeable in the city proper, whereas the language has remained active in the rural and metropolitan areas. After the Castille-Aragon unification, a Spanish-speaking elite established itself in the city. In more recent history, the establishment of Franco's military and administrative apparatus in Valencia further excluded Valencian from public life. Valencian recovered its official status, prestige and use in education after the transition to democracy in 1978. However, due to industrialisation in recent decades, Valencia has attracted immigration from other regions in Spain, and hence there is also a demographic factor for its declining social use. Due to a combination of these reasons, Valencia has become the bastion of anti-Catalan blaverism, which celebrates Valencian as merely folkloric, but rejects the existing standard which was adapted from Catalan orthography.
Spanish is currently the predominant language in the city proper but, thanks to the education system, most Valencians have basic knowledge of both Spanish and Valencian, and either can be used in the city. Valencia is therefore the second biggest Catalan-speaking city after Barcelona. Institutional buildings and streets are named in Valencian. The city is also home to many pro-Valencian political and civil organisations. Furthermore, education entirely in Valencian is offered in more than 70 state-owned schools in the city, as well as by the University of Valencia across all disciplines.
Is there an answer to this question: How many official languages does Valencia have?

Answer:
two
