The photoelectric effect will cause spacecraft exposed to sunlight to develop a positive charge. This can be a major problem, as other parts of the spacecraft are in shadow which will result in the spacecraft developing a negative charge from nearby plasmas. The imbalance can discharge through delicate electrical components.
Tritium (from Ancient Greek τρίτος (trítos) 'third') or hydrogen-3 (symbol T or 3 H) is a rare and radioactive isotope of hydrogen with half-life ~12.3 years. The nucleus of tritium (t, sometimes called a triton) contains one proton and two neutrons, whereas the nucleus of the common isotope hydrogen-1 (protium) contains one proton and zero neutrons, and that of a non-radioactive ...
Atmospheric electricity describes the electrical charges in the Earth's atmosphere (or that of another planet ). The movement of charge between the Earth's surface, the atmosphere, and the ionosphere is known as the global atmospheric electrical circuit. Atmospheric electricity is an interdisciplinary topic with a long history, involving ...
Description. The effective atomic number Z eff, (sometimes referred to as the effective nuclear charge) of an atom is the number of protons that an electron in the element effectively 'sees' due to screening by inner-shell electrons. It is a measure of the electrostatic interaction between the negatively charged electrons and positively charged ...
Average attendance last year was among the 10 worst in the NCAA’s top level. Yet Georgia State’s 32,000 students are still required to cover much of the costs. Over the past five years, students have paid nearly $90 million in mandatory athletic fees to support football and other intercollegiate athletics — one of the highest ...
Cost-of-living in America is still out of control — use these 3 'real assets' to protect your wealth today, ... She could keep the car after many miles and many years, thanks to the lifetime ...
The missing years in the Hebrew calendar refer to a chronological discrepancy between the rabbinic dating for the destruction of the First Temple in 422 BCE (3338 Anno Mundi) [1] and the academic dating of it in 587 BCE. In a larger sense, it also refers to the discrepancy between conventional chronology versus that of Seder Olam in what ...
CHARGE syndrome (formerly known as CHARGE association) is a rare syndrome caused by a genetic disorder. First described in 1979, the acronym "CHARGE" came into use for newborn children with the congenital features of c oloboma of the eye, h eart defects , a tresia of the nasal choanae , r estricted growth and/or development , g enital and/or ...
