Input: Planck constant
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 three terms define the Bohr magneton value?
Output: the reduced Planck constant, the elementary charge and the electron mass

Input: Israel
The following day, the armies of four Arab countriesEgypt, Syria, Transjordan and Iraqentered what had been British Mandatory Palestine, launching the 1948 ArabIsraeli War; Contingents from Yemen, Morocco, Saudi Arabia and Sudan joined the war.

Input: Brigham Young University
Many visitors to BYU, and Utah Valley as a whole, report being surprised by the culturally conservative environment. Brigham Young University's Honor Code, which all BYU students agree to follow as a condition of studying at BYU, prohibits the consumption of alcoholic beverages, tobacco, etc. As mentioned earlier, The Princeton Review has rated BYU the "#1 stone cold sober school" in the nation for several years running, an honor which the late LDS Church president Gordon B. Hinckley had commented on with pride. BYU's 2014 "#1 stone cold" sober rating marked the 17th year in a row that the school had earned that rating. BYU has used this and other honors awarded to the school to advertise itself to prospective students, showing that BYU is proud of the rating. According to the Uniform Crime Reports, incidents of crime in Provo are lower than the national average. Murder is rare, and robberies are about 1/10 the national average. Business Insider rated BYU as the #1 safest college campus in the nation.

What BYU environment seems to surprise many visitors to BYU as well as to the Utah Valley?
Output: culturally conservative
