Problem: Please answer a question about the following article about Planck constant:
The Faraday constant F is the charge of one mole of electrons, equal to the Avogadro constant NA multiplied by the elementary charge e. It can be determined by careful electrolysis experiments, measuring the amount of silver dissolved from an electrode in a given time and for a given electric current. In practice, it is measured in conventional electrical units, and so given the symbol F90. Substituting the definitions of NA and e, and converting from conventional electrical units to SI units, gives the relation to the Planck constant.
How does the Faraday constant relate to the Planck constant?
A: Substituting the definitions of NA and e, and converting from conventional electrical units to SI units, gives the relation to the Planck constant.
Problem: Please answer a question about the following article about Asthma:
There is no cure for asthma. Symptoms can be prevented by avoiding triggers, such as allergens and irritants, and by the use of inhaled corticosteroids. Long-acting beta agonists (LABA) or antileukotriene agents may be used in addition to inhaled corticosteroids if asthma symptoms remain uncontrolled. Treatment of rapidly worsening symptoms is usually with an inhaled short-acting beta-2 agonist such as salbutamol and corticosteroids taken by mouth. In very severe cases, intravenous corticosteroids, magnesium sulfate, and hospitalization may be required.
How can symptoms be prevented?
A: by avoiding triggers, such as allergens and irritants, and by the use of inhaled corticosteroids
Problem: Please answer a question about the following article about Kievan Rus%27:
Ahmad ibn Fadlan, an Arab traveler during the 10th century, provided one of the earliest written descriptions of the Rus': "They are as tall as a date palm, blond and ruddy, so that they do not need to wear a tunic nor a cloak; rather the men among them wear garments that only cover half of his body and leaves one of his hands free." Liutprand of Cremona, who was twice an envoy to the Byzantine court (949 and 968), identifies the "Russi" with the Norse ("the Russi, whom we call Norsemen by another name") but explains the name as a Greek term referring to their physical traits ("A certain people made up of a part of the Norse, whom the Greeks call [...] the Russi on account of their physical features, we designate as Norsemen because of the location of their origin."). Leo the Deacon, a 10th-century Byzantine historian and chronicler, refers to the Rus' as "Scythians" and notes that they tended to adopt Greek rituals and customs.
Which early traveler provided an early description of the Rus?
A: Ahmad ibn Fadlan
Problem: Please answer a question about the following article about Seattle:
The name "Seattle" appears on official Washington Territory papers dated May 23, 1853, when the first plats for the village were filed. In 1855, nominal land settlements were established. On January 14, 1865, the Legislature of Territorial Washington incorporated the Town of Seattle with a board of trustees managing the city. The town of Seattle was disincorporated January 18, 1867 and remained a mere precinct of King County until late 1869, when a new petition was filed and the city was re-incorporated December 2, 1869 with a Mayor-council government. The corporate seal of the City of Seattle carries the date "1869" and a likeness of Chief Sealth in left profile.
At what date did the name Seattle first appear on official papers?
A:
May 23, 1853
