Unlike low inflation, where the process of rising prices is protracted and not generally noticeable except by studying past market prices, hyperinflation sees a rapid and continuing increase in nominal prices and in the supply of money, and the nominal cost of goods.heories of hyperinflation generally look for a relationship between seigniorage and the inflation tax. In both Cagan's model and the neo-classical models, a tipping point occurs when the increase in money supply or the drop in the monetary base makes it impossible for a government to improve its financial position.
Comets Comets have a very small nucleus, a coma of gas and dust that is the most visible part and can be very large, a hydrogen envelope, a dust tail, and an ion tail. Comets ï§The cometâs tail always points away from the Sun, driven by the solar wind and radiation pressure. ï§ Comets have very eccentric orbits. ï§ Long-period comets (C/) have periods of hundreds of thousands, or even millions, of years. ï§ Short-period comets (P/) are less common, and have periods of less than 200 years.
Comets are basically dusty snowballs which orbit the Sun. They are made of ices, such as water, carbon dioxide, ammonia and methane, mixed with dust. These materials came from the time when the Solar System was formed. Comets have an icy center (nucleus) surrounded by a large cloud of gas and dust (called the coma). The coma is created as the ice in the nucleus is warmed by the Sun and vaporizes. Comets can develop two tails as they travel closer to the Sun: a straight gas tail and a curved dust tail. The gas tail is created by the solar wind, pushing gas away from the comet's coma and pointing straight back from the Sun. The dust in the coma is not affected by magnetic fields but is vaporized by the Sun's heat, and forms a curved tail which follows the comet's orbit.
