hello

In celestial mechanics, the Roche limit, also called Roche radius, is the distance in which a celestial body, held together only by its own gravity, will disintegrate due to a second celestial body's tidal forces exceeding the first body's gravitational self-attraction.[1] Inside the Roche limit, orbiting material disperses and forms rings whereas outside the limit material tends to coalesce. Calculated in 1848

Typically, the Roche limit applies to a satellite's disintegrating due to tidal forces induced by its primary, the body about which it orbits. Parts of the satellite that are closer to the primary are attracted more strongly by gravity from the primary than parts that are farther away; this disparity effectively pulls the near and far parts of the satellite apart from each other, and if the disparity (combined with any centrifugal effects due to the object's spin) is larger than the force of gravity holding the satellite together, it can pull the satellite apart. Some real satellites, both natural and artificial, can orbit within their Roche limits because they are held together by forces other than gravitation. Objects resting on the surface of such a satellite would be lifted away by tidal forces. A weaker satellite, such as a comet, could be broken up when it passes within its Roche limit.

Since, within the Roche limit, tidal forces overwhelm the gravitational forces that might otherwise hold the satellite together, no satellite can gravitationally coalesce out of smaller particles within that limit. Indeed, almost all known planetary rings are located within their Roche limit. (Notable exceptions are Saturn's E-Ring and Phoebe ring. These two rings could possibly be remnants from the planet's proto-planetary accretion disc that failed to coalesce into moonlets, or conversely have formed when a moon passed within its Roche limit and broke apart.)

The Roche limit is not the only factor that causes comets to break apart. Splitting by thermal stress, internal gas pressure and rotational splitting are other ways for a comet to split under stress.

The Roche limit is the minimum distance to which a large satellite can approach its primary body without being torn apart by tidal forces. If satellite and primary are of similar composition, the theoretical limit is about 2 1/2 times the radius of the larger body. The rings of Saturn lie inside Saturn's Roche limit and may be the debris of a demolished moon. The limit was first calculated by the French astronomer douard Roche (1820-83). Artificial satellites are too small to develop substantial tidal stresses.

beans???

beans!

Beans originated in Central America around 10,000 years ago with the Mayans. The Aztec people favored a specific type of bean called Phaseolus vulgaris molle. They also developed a method for drying these beans to make them last longer. Over time, this allowed people to travel farther with less provisions, which changed travel and trade patterns throughout the world. These bean farmers were among the first to successfully cross over desolate terrains that had limited vegetation during their migration across the American continents. Subsequently, they brought their bean farming skills with them as they spread across most of Central and South America. Today, most countries have their own characteristics when it comes to beans. For example, the tradition of serving beans at Thanksgiving dinner in America is due to the Pilgrims' origin from Plymouth in Massachusetts. Along with this appetizer, they also served green beans as a side dish; this is because green beans were a common vegetable in the American colonies at that time.

Various types of beans are widely cultivated all over the world- including Africa, Australia and China. These are known as pulse crops or legumes, which refer to vegetable proteins rather than animal proteins like meat or eggs. There are many different types of beans with varying degrees of nutritional value. Black beans from South America contain a large amount of fiber; red kidney beans from North America are high in protein; white navy bean soup is popular in India; and cannellini beans from Italy provide lots of calcium. Plus, cannellini beans have more antioxidants than any other bean variety. Many people enjoy cooking with different types of beans every day- perhaps due to their versatility and nutritional value.
