The Chandrasekhar limit is approximately 1.44 solar masses. It represents the maximum mass of a white dwarf star that can be supported against gravitational collapse by electron degeneracy pressure. Beyond this limit, the star collapses into a neutron star or black hole. (finish=stop tokens=55 time=3.4s tps=31.7) ---------------------------------------------------------------------- Q02 [physics] Which bosons mediate the weak nuclear force? The weak nuclear force is mediated by the W and Z bosons. The W bosons (W⁺ and W⁻) mediate charged-current interactions, while the Z boson mediates neutral-current interactions. These bosons are massive and short-ranged, distinguishing them from massless photons of electromagnetism.

The Davisson-Germer experiment confirmed the wave nature of electrons, specifically verifying Louis de Broglie's hypothesis that particles exhibit wave-like properties. It demonstrated that electrons can diffract like waves when scattered by a crystal lattice, providing direct evidence for quantum mechanics' wave-particle duality. The experiment measured electron diffraction patterns consistent with de Broglie's wavelength formula, λ = h/p. This confirmed that matter, not just light, has wave-like behavior.

A racemic mixture is a 1:1 mixture of two enantiomers (mirror-image isomers) of a chiral compound, resulting in a net optical activity of zero. It is optically inactive because the rotations of plane-polarized light by the two enantiomers cancel each other out. This mixture is often formed during chemical reactions that produce chiral products without stereoselectivity.

Nominal GDP measures a country’s economic output using current prices, while real GDP adjusts for inflation by using constant prices from a base year. This adjustment allows real GDP to reflect actual changes in output, whereas nominal GDP can be distorted by price changes. Real GDP is a more accurate measure of economic growth over time.

Gresham's law states that "bad money drives out good money" when both are in circulation, as people hoard the more valuable (good) currency and spend the less valuable (bad) one. This occurs when governments debase currency, reducing its intrinsic value, leading to the disappearance of higher-quality money from circulation. The law is named after Sir Thomas Gresham, a 16th-century English financier.
