QUES: The gyromagnetic ratio is the constant of proportionality between the frequency of nuclear magnetic resonance (or electron paramagnetic resonance for electrons) and the applied magnetic field B: = B. It is difficult to measure gyromagnetic ratios precisely because of the difficulties in precisely measuring B, but the value for protons in water at 7002298150000000000♠️25 C is known to better than one part per million. The protons are said to be "shielded" from the applied magnetic field by the electrons in the water molecule, the same effect that gives rise to chemical shift in NMR spectroscopy, and this is indicated by a prime on the symbol for the gyromagnetic ratio, p. The gyromagnetic ratio is related to the shielded proton magnetic moment p, the spin number I (I = 12 for protons) and the reduced Planck constant.
What is never related to the shielded proton magnetic moment?

ANS: unanswerable

QUES: Bacteria (i/bktri/; singular: bacterium) constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a number of shapes, ranging from spheres to rods and spirals. Bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep portions of Earth's crust. Bacteria also live in symbiotic and parasitic relationships with plants and animals. They are also known to have flourished in manned spacecraft.
What environments can bacteria live?

ANS: present in most of its habitats

QUES: The house which forms the architectural core of the palace was built for the first Duke of Buckingham and Normanby in 1703 to the design of William Winde. The style chosen was of a large, three-floored central block with two smaller flanking service wings. Buckingham House was eventually sold by Buckingham's descendant, Sir Charles Sheffield, in 1761 to George III for 21,000. Sheffield's leasehold on the mulberry garden site, the freehold of which was still owned by the royal family, was due to expire in 1774.
In what year was the leasehold of the Mulberry site due to expire?

ANS: 1774

QUES: In polygynous species with considerable sexual dimorphism, males tend to return earlier to the breeding sites than their females. This is termed protandry.
Why do males in polygynous species return before the females?

ANS:
sexual dimorphism
