As n increases, the valence electrons are, on average, farther from the nucleus, and experience less nuclear pull due to the shielding by the “core” electrons. As a result, Zeff decreases slightly going down a group. ...

... NMR signal of the nucleus. The question asks for a comparison between the frequencies required for the observation of protons (1H) and phosphorus (31P) in the same magnet. The magnetogyric ratio of 31P is 0.405 times that of 1H so the frequency required to observe 31P will be scaled by the same fact ...

... So the potential energy stored in the capacitor increases. Where does the energy come from? The simple answer is the battery. Thus we see the use of a dielectric in a circuit: it increases the stored energy in the capacitor. Also, it keeps the plates from sticking together due to coulomb attraction! ...

Time in physics
Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
