Question: The gyromagnetic ratio is the constant proportion between the magentic field and what?
Answer: the frequency ν of nuclear magnetic resonance

Question: How does the water molecule impact the effect of magnetic fields on protons?
Answer: The protons are said to be "shielded" from the applied magnetic field by the electrons in the water molecule

Question: What three factors impact the gyromagnetic ratio?
Answer: related to the shielded proton magnetic moment μ′p, the spin number I (I = 1⁄2 for protons) and the reduced Planck constant.

Question: The gyromagnetic ratio is often difficult to determine due to difficulty accurately determining the value of what?
Answer: the applied magnetic field B

Question: How many methods of measuring the gyromagnetic ratio are there?
Answer: there are two methods of measuring the value

Question: How do conversion factors compare in "low-field" and "high-field" methods of measuring the gyromagnetic ratio?
Answer: the conversion factors are different in the two cases

Question: Which method is of interest in determining the Planck constant?
Answer: Only the high-field value Γ′p-90(hi) is of interest in determining the Planck constant

Question: Why is the measurement of electric current an issue in the estimate of the gyromagnetic ratio?
Answer: electric current: this is invariably measured in conventional amperes rather than in SI amperes

Question: What is the Faraday constant?
Answer: the charge of one mole of electrons

Question: How is the Faraday constant determined?
Answer: by careful electrolysis experiments, measuring the amount of silver dissolved from an electrode in a given time and for a given electric current.

Question: How does the Faraday constant relate to the Planck constant?
Answer: Substituting the definitions of NA and e, and converting from conventional electrical units to SI units, gives the relation to the Planck constant.

Question: How is the Farday constant value quickly calculated?
Answer: the Avogadro constant NA multiplied by the elementary charge e

Question: What is the primary method for determining the Avogadro constant?
Answer: The X-ray crystal density method

Question: The Avogadro constant is determined to be the ratio between what two factors in the X-ray crystal density method?
Answer: the volume of the unit cell of a crystal, measured by X-ray crystallography, and the molar volume of the substance

Question: What element is used typically to establish Avogadro's constant?
Answer: Crystals of silicon

Question: How is unit cell volume calculated?
Answer: from the spacing between two crystal planes referred to as d220

Question: Calculating molar volume requires knowledge of what two factors?
Answer: the density of the crystal and the atomic weight of the silicon used

Question: What measurement is deemed most important to redefine in terms of physical constants?
Answer: the kilogram

Question: What is the shape of the object that establishes the base unit of the kilogram?
Answer: cylinder

Question: What alloy is the base unit of the kilogram made from?
Answer: platinum–iridium

Question: Where is the base unit for the kilogram kept?
Answer: in a vault just outside Paris

Question: Where would the decision to change the definition of the kilogram have occured at the earliest?
Answer: the General Conference on Weights and Measures in 2011

Question: Was the Planck constant the only option for redefining the kilogram?
Answer: The Planck constant is a leading contender to form the basis of the new definition, although not the only one

Question: The mass of a resting body with what energy would be equal to a kilogram?
Answer: 7050135639273999999♠135639274×1042 Hz
