Article: The Tribhuvan Museum contains artifacts related to the King Tribhuvan (19061955). It has a variety of pieces including his personal belongings, letters and papers, memorabilia related to events he was involved in and a rare collection of photos and paintings of Royal family members. The Mahendra Museum is dedicated to king Mahendra of Nepal (19201972). Like the Tribhuvan Museum, it includes his personal belongings such as decorations, stamps, coins and personal notes and manuscripts, but it also has structural reconstructions of his cabinet room and office chamber. The Hanumandhoka Palace, a lavish medieval palace complex in the Durbar, contains three separate museums of historic importance. These museums include the Birendra museum, which contains items related to the second-last monarch, Birendra of Nepal.

Question: How many museums are in the Hanumandhoka Palace?
Ans: three

Article: While inert gas reduces filament evaporation, it also conducts heat from the filament, thereby cooling the filament and reducing efficiency. At constant pressure and temperature, the thermal conductivity of a gas depends upon the molecular weight of the gas and the cross sectional area of the gas molecules. Higher molecular weight gasses have lower thermal conductivity, because both the molecular weight is higher and also the cross sectional area is higher. Xenon gas improves efficiency because of its high molecular weight, but is also more expensive, so its use is limited to smaller lamps.

Question: How does the molecular weight of a gas relate to thermal conductivity?
Ans: Higher molecular weight gasses have lower thermal conductivity

Article: John inherited a sophisticated system of administration in England, with a range of royal agents answering to the Royal Household: the Chancery kept written records and communications; the Treasury and the Exchequer dealt with income and expenditure respectively; and various judges were deployed to deliver justice around the kingdom. Thanks to the efforts of men like Hubert Walter, this trend towards improved record keeping continued into his reign. Like previous kings, John managed a peripatetic court that travelled around the kingdom, dealing with both local and national matters as he went. John was very active in the administration of England and was involved in every aspect of government. In part he was following in the tradition of Henry I and Henry II, but by the 13th century the volume of administrative work had greatly increased, which put much more pressure on a king who wished to rule in this style. John was in England for much longer periods than his predecessors, which made his rule more personal than that of previous kings, particularly in previously ignored areas such as the north.

Question: Who dealt with income and expenditure?
Ans:
the Treasury and the Exchequer
