Hi bobbym.

The Answer #5667 (Bombay and Calcutta respectively) are correct! Excellent!

#5669. Name the term in Physics - A liquid that becomes strongly magnetized in the presence of a magnetic field. It was invented in 1963 by NASA's Steve Papell as a liquid rocket fuel that could be drawn toward a pump inlet in a weightless environment by applying a magnetic field. It has been submersed in sugar water. Sugar has been added to increase the density of the water to the point where the it appears weightless. They are colloidal liquids made of nanoscale ferromagnetic, or ferrimagnetic, particles suspended in a carrier fluid (usually an organic solvent or water). Each tiny particle is thoroughly coated with a surfactant to inhibit clumping. Large ferromagnetic particles can be ripped out of the homogeneous colloidal mixture, forming a separate clump of magnetic dust when exposed to strong magnetic fields. The magnetic attraction of nanoparticles is weak enough that the surfactant's Van der Waals force is sufficient to prevent magnetic clumping or agglomeration. They usually do not retain magnetization in the absence of an externally applied field and thus are often classified as "superparamagnets" rather than ferromagnets.

#5670. Name the Scottish physician and chemist (16 April 1728 – 6 December 1799), known for his discoveries of magnesium, latent heat, specific heat, and carbon dioxide. He was Professor of Anatomy and Chemistry at the University of Glasgow for 10 years from 1756, and then Professor of Medicine and Chemistry at the University of Edinburgh from 1766, teaching and lecturing there for more than 30 years. The chemistry buildings at both the University of Edinburgh and the University of Glasgow are named after him.

#5673. Name the 24,514-square-kilometre (9,465 sq mi) lake in central North America, in the province of Manitoba, Canada, with its southern tip about 55 kilometres (34 mi) north of the city of the same name. It is the largest lake within the borders of southern Canada, and it is part of the most undeveloped large watershed of southern Canada.
It is the sixth-largest freshwater lake in Canada,and the third-largest freshwater lake contained entirely within Canada, but it is relatively shallow (mean depth of 12 m (39 ft)) excluding a narrow 36 m (118 ft) deep channel between the northern and southern basins. It is the eleventh-largest freshwater lake on Earth. The east side of the lake has pristine boreal forests and rivers that are being promoted as a potential United Nations World Heritage Park. The lake is elongated in shape and is 416 km (258 mi) from north to south, with remote sandy beaches, large limestone cliffs, and many bat caves in some areas. Manitoba Hydro uses the lake as one of the largest reservoirs in the world. There are many islands in the lake, most of them undeveloped.

#5674. Name the third longest river in Australia, measuring 1,472 kilometres (915 mi) from its source in northern New South Wales to its confluence with the Murray River at Wentworth, New South Wales. Including its longest contiguous tributaries it is 2,844 km (1,767 mi) long, making it the longest river system in Australia. It is the outback's most famous waterway. It has been in poor health, suffering from overuse of its waters, pollution from pesticide runoff and prolonged drought. In some years it has barely flowed at all. The river has a high salt content and declining water quality. Increased rainfall in its catchment in 2010 has improved flow, but the health of the river will depend on long-term management.

Hi bobbym,

#5675. The Arabian Sea is a region of the northern Indian Ocean bounded on the north by Pakistan and Iran, on the west by northeastern Somalia and the Arabian Peninsula, and on the east by India. An ancient name was the Erythraean Sea and Persian Sea. What is Arabian Sea's surface area approximately (in square kilometers or square miles)?
The maximum width of the Sea is approximately 2,400 km (1,490 mi), and its maximum depth is 4,652 metres (15,262 ft). The biggest river flowing into the Sea is the Indus River.
The Arabian Sea has two important branches — the Gulf of Aden in the southwest, connecting with the Red Sea through the strait of Bab-el-Mandeb; and the Gulf of Oman to the northwest, connecting with the Persian Gulf. There are also the gulfs of Khambhat and Kutch on the Indian coast.

#5676. Name the sea : Gulf of the northeast Atlantic Ocean located south of the Celtic Sea. It lies along the western coast of France from Brst south to the Spanish border, and the northern coast of Spain west to Cape Ortegal. The average depth is 1,744 metres (5,722 ft) and the greatest depth is 4,735 metres (15,535 ft). Parts of the continental shelf extend far into the bay, resulting in fairly shallow waters in many areas and thus the rough seas for which the region is known. It is home to some of the Atlantic Ocean's fiercest weather. Large storms occur in the bay, especially during the winter months.

#5679. Name the American poet (March 26, 1874 – January 29, 1963) . His work was initially published in England before it was published in America. He is highly regarded for his realistic depictions of rural life and his command of American colloquial speech. His work frequently employed settings from rural life in New England in the early twentieth century, using them to examine complex social and philosophical themes. One of the most popular and critically respected American poets of the twentieth century, he was honored frequently during his lifetime, receiving four Pulitzer Prizes for Poetry. He became one of America's rare "public literary figures, almost an artistic institution." He was awarded the Congressional Gold Medal in 1960 for his poetical works. On July 22, 1961, he was named Poet laureate of Vermont. Notable works - A Boy's Will; North of Boston.

#5680. Name the ancient Indian collection of interrelated animal fables in verse and prose, arranged within a frame story. The original Sanskrit work, which some scholars believe was composed around the 3rd century BCE, is attributed to Vishnu Sharma. It is based on older oral traditions, including "animal fables that are as old as we are able to imagine". It is "certainly the most frequently translated literary product of India", and these stories are among the most widely known in the world. To quote Edgerton (1924):

...there are recorded over two hundred different versions known to exist in more than fifty languages, and three-fourths of these languages are extra-Indian. As early as the eleventh century this work reached Europe, and before 1600 it existed in Greek, Latin, Spanish, Italian, German, English, Old Slavonic, Czech, and perhaps other Slavonic languages. Its range has extended from Java to Iceland... [In India,] it has been worked over and over again, expanded, abstracted, turned into verse, retold in prose, translated into medieval and modern vernaculars, and retranslated into Sanskrit. And most of the stories contained in it have "gone down" into the folklore of the story-loving Hindus, whence they reappear in the collections of oral tales gathered by modern students of folk-stories.

#5683. Name the general term (Physics) that refers to any reduction in the strength of a signal. It occurs with any type of signal, whether digital or analog. Sometimes called loss, it is a natural consequence of signal transmission over long distances. In electrical engineering and telecommunications, it affects the propagation of waves and signals in electrical circuits, in optical fibers, and in air (radio waves).

#5684. Name the physical phenomenon in which the filling of an inner-shell vacancy of an atom is accompanied by the emission of an electron from the same atom. When a core electron is removed, leaving a vacancy, an electron from a higher energy level may fall into the vacancy, resulting in a release of energy. Although most of the time this energy is released in the form of an emitted photon, the energy can also be transferred to another electron, which is ejected from the atom.

#5685. Name the scientist - A true polymath, the topics he covered during his career include comets, the motion of light, the rotation of Jupiter, gravity, human memory and the properties of air. In all of his studies and demonstrations, he adhered to the scientific method of experimentation and observation. Hooke also utilized the most up-to-date instruments in his many projects.
His most important publication was Micrographia, a 1665 volume documenting experiments he had made with a microscope. In this groundbreaking study, he coined the term "cell" while discussing the structure of cork. He also described flies, feathers and snowflakes, and correctly identified fossils as remnants of once-living things.
The 1678 publication of his Lectures of Spring shared his theory of elasticity; in what came to be known as low named after him, he stated that the force required to extend or compress a spring is proportional to the distance of that extension or compression. In an ongoing, related project, his worked for many years on the invention of a spring-regulated watch.

#5686. Name the pressure chamber used to sterilize equipment and supplies by subjecting them to high pressure saturated steam at 121 °C (249°F) for around 15-20 minutes depending on the size of the load and the contents. It was invented by Charles Chamberland in 1879, although a precursor known as the steam digester was created by Denis Papin in 1679.

#5687. Name the chemical element with atomic number 34. It is a nonmetal with properties that are intermediate between those of its periodic table column-adjacent chalcogen elements sulfur and tellurium. It rarely occurs in its elemental state in nature, or as pure ore compounds. It was discovered in 1817 by Jöns Jacob Berzelius, who noted the similarity of the new element to the previously known tellurium (named for the Earth). It is found in metal sulfide ores, where it partially replaces the sulfur. Commercially, it is produced as a byproduct in the refining of these ores, most often during production.

#5688. Name the chemical element with atomic number 38. An alkaline earth metal, it is a soft silver-white or yellowish metallic element that is highly reactive chemically. The metal turns yellow when it is exposed to air. It has physical and chemical properties similar to those of its two neighbors calcium and barium. It occurs naturally in the minerals celestine, putnisite and strontianite.

#5689. Name the British Marxist historian (9 June 1917 – 1 October 2012) of the rise of industrial capitalism, socialism, and nationalism. His best-known works include his trilogy about what he called the "long 19th century" (The Age of Revolution: Europe 1789–1848, The Age of Capital: 1848–1875 and The Age of Empire: 1875–1914), The Age of Extremes on the short 20th century, and an edited volume that introduced the influential idea of "invented traditions".

#5690. Name the author (6 March 1927 – 17 April 2014) : Colombian novelist, short-story writer, screenwriter and journalist, known affectionately as Gabo or Gabito throughout Latin America. 'One Hundred Years of Solitude' is a 1967 novel by Colombian author that tells the multi-generational story of the Buendía family, whose patriarch, José Arcadio Buendía, founds the town of Macondo, the metaphoric Colombia. The magical realist style and thematic substance of One Hundred Years of Solitude established it as an important, representative novel of the literary Latin American Boom of the 1960s and 1970s, which was stylistically influenced by Modernism (European and North American) and the Cuban Vanguardia (Avant-Garde) literary movement. 'One Hundred Years of Solitude' was first published in Spanish in 1967; it has subsequently has been translated into thirty-seven languages and has sold more than 30 million copies. The novel remains widely acclaimed today, and is considered by many to be his masterpiece.

Hi bobbym,

#5691. What does the abbreviation PTBT signify? (in connection with nuclear weapons)

#5692. Q.E.D. is an initialism of the Latin phrase quod erat demonstrandum, meaning "which is what had to be proven". The phrase is traditionally placed in its abbreviated form at the end of a mathematical proof or philosophical argument when what was specified in the enunciation—and in the setting-out—has been exactly restated as the conclusion of the demonstration. The abbreviation thus signals the completion of the proof.
What do the abbreviations Q.E.F. and Q.E.I signify?
