Beta decay is a type of radioactive decay where the nucleus emits a beta particle, used in medical applications. It occurs when an atom is unstable due to excess neutrons or protons, converting them to stabilize the nucleus and transforming the atom into another element. Beta particles can be electrons or positrons, and have a […]
Alpha decay is a type of radioactive decay where an alpha particle is emitted from a heavy element to become more stable. The strong nuclear force holds the nucleus together, but in large nuclei, particles may be ejected, causing radioactivity. Alpha particles consist of two protons and two neutrons and can be stopped by paper […]
Weather balloons measure atmospheric gradient, including ambient and adiabatic rates, important for meteorology. International standard lapse rates vary due to inversion layers. Dry adiabatic lapse rate (DAR) cools air packets as they rise, while saturated adiabatic gradient (SAR) varies with moisture. Stable atmospheres occur when ambient gradient is greater than DAR. Super-adiabatic gradient in southwestern […]
Radon is a naturally occurring radioactive gas produced by the decay of uranium. It decays into other radioactive elements, releasing alpha and beta particles. Radon is dangerous to humans because it can cause cancer if ingested or breathed in. It is present in many homes and can collect where there is no ventilation. Radon decay […]
Time decay is the decline in the value of an option just before its expiration date. Investors need to identify the signs of time decay and sell the option before the decline continues. Examining the reasons for the decline can help determine whether to sell or hold on. Long options are at risk, while short […]
