Problem: A watt balance is an instrument for comparing two powers, one of which is measured in SI watts and the other of which is measured in conventional electrical units. From the definition of the conventional watt W90, this gives a measure of the product KJ2RK in SI units, where RK is the von Klitzing constant which appears in the quantum Hall effect. If the theoretical treatments of the Josephson effect and the quantum Hall effect are valid, and in particular assuming that RK = h/e2, the measurement of KJ2RK is a direct determination of the Planck constant.
What is a watt balance?
The answer is the following: an instrument for comparing two powers, one of which is measured in SI watts and the other of which is measured in conventional electrical units

Problem: Parallel with the growth of specialized agencies for conducting or supporting statescraft in the second half of the 20th century has been the collection of resources for scholarship and research typically in university settings. Most universities teaching the liberal arts have library and museum collections. These are not new; however, the erection of these into "centres" of national and international interest in the second half of the 20th century have created larger databases not available to the scholars of the past. Many of these focus on the Ancient Near East or Near East in the sense of Ancient Near East.
What has had parallel growth of in the 20th century?
The answer is the following: the collection of resources

Problem: The city is home or birthplace to a number of contemporary musicians such as R'n'B singer Craig David, Coldplay drummer Will Champion, former Holloways singer Rob Skipper as well as 1980s popstar Howard Jones. Several rock bands were formed in Southampton, including Band of Skulls, The Delays, Bury Tomorrow, Heart in Hand, Thomas Tantrum (disbanded in 2011) and Kids Can't Fly (disbanded in 2014). James Zabiela, a highly regarded and recognised name in dance music, is also from Southampton.
What popular RnB singer hails from Southampton?
The answer is the following: Craig David

Problem: Along with four other scientists and various military personnel, von Neumann was included in the target selection committee responsible for choosing the Japanese cities of Hiroshima and Nagasaki as the first targets of the atomic bomb. Von Neumann oversaw computations related to the expected size of the bomb blasts, estimated death tolls, and the distance above the ground at which the bombs should be detonated for optimum shock wave propagation and thus maximum effect. The cultural capital Kyoto, which had been spared the bombing inflicted upon militarily significant cities, was von Neumann's first choice, a selection seconded by Manhattan Project leader General Leslie Groves. However, this target was dismissed by Secretary of War Henry L. Stimson.
Who dismissed von Neuamann's primary target city?
The answer is the following:
Secretary of War Henry L. Stimson.
