Here is a question about this article: The Bohr magneton and the nuclear magneton are units which are used to describe the magnetic properties of the electron and atomic nuclei respectively. The Bohr magneton is the magnetic moment which would be expected for an electron if it behaved as a spinning charge according to classical electrodynamics. It is defined in terms of the reduced Planck constant, the elementary charge and the electron mass, all of which depend on the Planck constant: the final dependence on h1/2 (r2 > 0.995) can be found by expanding the variables.
What is the answer to this question: What three terms define the Bohr magneton value?
****
So... the reduced Planck constant, the elementary charge and the electron mass


Here is a question about this article: The clergy was divided into two types: the secular clergy, who lived out in the world, and the regular clergy, who lived under a religious rule and were usually monks. Throughout the period monks remained a very small proportion of the population, usually less than one per cent. Most of the regular clergy were drawn from the nobility, the same social class that served as the recruiting ground for the upper levels of the secular clergy. The local parish priests were often drawn from the peasant class. Townsmen were in a somewhat unusual position, as they did not fit into the traditional three-fold division of society into nobles, clergy, and peasants. During the 12th and 13th centuries, the ranks of the townsmen expanded greatly as existing towns grew and new population centres were founded. But throughout the Middle Ages the population of the towns probably never exceeded 10 per cent of the total population.
What is the answer to this question: What social class did many members of the regular clergy come from?
****
So... the nobility


Here is a question about this article: Doug Morris, who was head of Warner Music Group, then Universal Music, became chairman and CEO of the company on July 1, 2011. Sony Music underwent a restructuring after Morris' arrival. He was joined by L.A. Reid, who became the chairman and CEO of Epic Records. Under Reid, multiple artists from the Jive half of the former RCA/Jive Label Group moved to Epic. Peter Edge became the new CEO of the RCA Records unit. The RCA Music Group closed down Arista, J Records and Jive Records in October 2011, with the artists from those labels being moved to RCA Records.
What is the answer to this question: Who became the CEO of RCA Records?
****
So...
Peter Edge
