Hi bobbym and Relentless,

The Answer #5759 (Capacitance : bobbym) and #5760 (200 mg : Relentless) are correct! Good work!

#5761. The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Along with the nitrogen cycle and the water cycle, the carbon cycle comprises a sequence of events that are key to making the Earth capable of sustaining life; it describes the movement of carbon as it is recycled and reused throughout the biosphere. Name the two scientists who discovered and one who popularized it.

#5762. The Carnot cycle is a theoretical thermodynamic cycle proposed by Nicolas Léonard Sadi Carnot. It which year? (It was expanded upon by others.) It provides an upper limit on the efficiency that any classical thermodynamic cycle can achieve during the conversion of thermal energy into work, or conversely, the efficiency of a refrigeration system in creating a temperature difference (e.g. refrigeration) by the application of work to the system. It is not an actual thermodynamic cycle but is a theoretical construct.

Hi bobbym,

The Answer #5761 is partially correct! Good work!

#5763. Name the term is Physics / Telecommunications - It is a waveform (usually sinusoidal) that is modulated (modified) with an input signal for the purpose of conveying information.

#5764. Name the instrument - An instrument for measuring vertical distances in cases where a scale cannot be placed very close to the points whose distance apart is desired. The instrument consists essentially of an accurately graduated scale and a horizontal telescope capable of being moved up and down a rigid vertical column. The position of the telescope can be read by means of an attached Vernier scale. In measuring the vertical distance between two points, the instrument must first be leveled. Next, the cross hair in the eyepiece of the horizontal telescope is brought into coincidence with the image of one point and the position of the telescope noted; the cross hair is then brought into coincidence with the image of the other point and the new position of the telescope noted. The difference between these readings is the vertical distance required.

Hi bobbym,

The Answer #5764, Cathetometer, is correct! Excellent!

#5765. Name the term is Physics / Chemistry - The process of hardening the surface of a metal object while allowing the metal deeper underneath to remain soft, thus forming a thin layer of harder metal at the surface. For iron or steel with low carbon content, which has poor to no hardenability of its own, the process involves infusing additional carbon into the case. It is usually done after the part has been formed into its final shape, but can also be done to increase the hardening element content of bars to be used in a pattern welding or similar process.

#5666. Name the term in Physics / Geometry - It is the curve that an idealized hanging chain or cable assumes under its own weight when supported only at its ends. The curve has a U-like shape, superficially similar in appearance to a parabola, but it is not a parabola: it is a (scaled, rotated) graph of the hyperbolic cosine. The it is also called the alysoid, chainette, or, particularly in the material sciences, funicular. Mathematically, the curve is the graph of the hyperbolic cosine function. The surface of revolution of the curve is a minimal surface, specifically a minimal surface of revolution. The mathematical properties of the curve were first studied by Robert Hooke in the 1670s, and its equation was derived by Leibniz, Huygens and Johann Bernoulli in 1691.

I'm not sure that 95% of the world knows much at all about metallurgy. If you break into the top 5%, there are still over 350 million people who know more than you. That's a hell of a lot of people, probably everyone with an interest in the topic.

Hi bobbym and Relentless,

Both the Answers, #5765 and #5766, are correct! Marvelous!

#5767. Name the term / phrase in Physics - An expression of the meaning of quantum mechanics that was largely devised in the years 1925 to 1927 by Niels Bohr and Werner Heisenberg. It remains one of the most commonly taught interpretations of quantum mechanics. According to it, physical systems generally do not have definite properties prior to being measured, and quantum mechanics can only predict the probabilities that measurements will produce certain results. The act of measurement affects the system, causing the set of probabilities to reduce to only one of the possible values immediately after the measurement. This feature is known as wavefunction collapse.

#5768. Name the term / phrase in Physics - The apparent deflection of moving objects when the motion is described relative to a rotating reference frame. In a reference frame with clockwise rotation, the deflection is to the left of the motion of the object; in one with counter-clockwise rotation, the deflection is to the right. Although recognized previously by others, the mathematical expression for the force appeared in an 1835 paper, in connection with the theory of water wheels. Early in the 20th century, the term force began to be used in connection with meteorology.

Excellent, Relentless (#5767) and bobbym (#5768)!

#5769. Name the term in Optics - In optics, it is the envelope of light rays reflected or refracted by a curved surface or object, or the projection of that envelope of rays on another surface.

#5770. Name the term in Physics - Small liquid-free zones ("bubbles" or "voids") – that are the consequence of forces acting upon the liquid. It usually occurs when a liquid is subjected to rapid changes of pressure that cause the formation of cavities where the pressure is relatively low. When subjected to higher pressure, the voids implode and can generate an intense shock wave.

Hi bobbym,

The Answer #5770 is correct! Good work!

#5771. The cell, invented by English engineer in 1873, is a wet-chemical cell (colloquially: battery) that produces a highly stable voltage. In 1893, the output of it at 15 C was defined by the International Electrical Congress as 1.434 volts, and this definition became law in the United States in 1894. This definition was later supplanted by one based on the Weston cell. Name the term in Physics.

#5772. Liquefaction of helium (4He) with the precooled Hampson-Linde cycle led to a Nobel Prize for Heike Kamerlingh Onnes. In which year? (At ambient pressure the boiling point of liquefied helium is 4.22 K (-268.93°C). Below 2.17 K liquid

becomes a superfluid (Nobel Prize 1978, Pyotr Kapitsa) and shows characteristic properties such as heat conduction through second sound, zero viscosity and the fountain effect among others.)

Hi bobbym,

#5773. CNB is the universe's background particle radiation composed of neutrinos. They are sometimes known as relic neutrinos. What does the abbreviation CNB signify?

#5774. Name the term in Astronomy - The notion that the distribution of matter in the universe is homogeneous and isotropic when viewed on a large enough scale, since the forces are expected to act uniformly throughout the universe, and should, therefore, produce no observable irregularities in the large scale structuring over the course of evolution of the matter field that was initially laid down by the Big Bang.

Hi bobbym,

The Answer #5774 is correct! Excellent!

#5775. Karl Ferdinand Braun (6 June 1850 – 20 April 1918) was a German inventor, physicist and Nobel laureate in physics. Braun contributed significantly to the development of radio and television technology: he shared with Guglielmo Marconi the 1909 Nobel Prize in Physics. What is his contribution to Physics?

#5776. Name the branch of Physics - It describes the motion of macroscopic objects, from projectiles to parts of machinery, as well as astronomical objects, such as spacecraft, planets, stars, and galaxies. Besides this, many specializations within the subject deal with solids, liquids and gases and other specific sub-topics. It also provides extremely accurate results as long as the domain of study is restricted to large objects and the speeds involved do not approach the speed of light. When the objects being dealt with become sufficiently small, it becomes necessary to introduce the other major sub-field of mechanics, quantum mechanics, which reconciles the macroscopic laws of physics with the atomic nature of matter and handles the wave–particle duality of atoms and molecules.

Hi bobbym,

The Answers #5775 (Cathode ray tube) and #5776 (Classical mechanics) are perfect! Splendid!

#5777. Name the term is Physics - The random motion of particles suspended in a fluid (a liquid or a gas) resulting from their collision with the quick atoms or molecules in the gas or liquid. This transport phenomenon is named after a botanist. In 1827, while looking through a microscope at particles trapped in cavities inside pollen grains in water, he noted that the particles moved through the water but was not able to determine the mechanisms that caused this motion.

#5778. Name the term is Physics - An electrical disruptive discharge similar to a corona discharge that takes place between two electrodes with a high voltage between them, embedded in a nonconducting fluid, usually air. It is characterized by multiple luminous writhing plasma streamers composed of ionized particles, which repeatedly strike out from the electrode, often with a crackling sound.

#5779. Name the term in Physics - A pewter-type alloy favoured for its silvery appearance and smooth surface. The composition is approximately and typically 92% tin, 6% antimony, and 2% copper. It was first produced in 1769 or 1770; it was created by James Vickers after purchasing the formula from a dying friend. It was originally known as "Vickers White Metal" when made under contract by the Sheffield manufacturers Ebenezer Hancock and Richard Jessop. In 1776 James Vickers took over the manufacturing himself and remained as owner until his death in 1809, when the company passed to his son, John, and Son-in-Law, Elijah West. In 1836 the company was sold to John Vickers's nephew Ebenezer Stacey (the son of Hannah Vickers and John Stacey).

#5780. Name the term is Physics - A traditional unit of work equal to about 1055 joules. It is the amount of work needed to raise the temperature of one pound of water by one degree Fahrenheit (Physical analogue: one four-inch wooden kitchen match consumed completely generates approximately this unit. In science, the joule, the SI unit of energy, has largely replaced the unit. Definition - It is the amount of heat required to raise the temperature of 1 avoirdupois pound of liquid water by 1 degree Fahrenheit at a constant pressure of one atmosphere.

Hi bobbym,

The Answer #5780 (The British thermal unit (BTU or Btu)) is correct! Neat work!

#5781. Name the term / phrase in Physics - It is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium at a speed greater than the phase velocity of light in that medium. The characteristic blue glow of an underwater nuclear reactor is due to the radiation. It is named after Soviet scientist, the 1958 Nobel Prize winner who was the first to detect it experimentally.

#5782. Name the term / phrase in Physics - A European research organization that operates the largest particle physics laboratory in the world. Established in 1954, the organization is based in a northwest suburb of Geneva on the Franco–Swiss border, (46°14′3″N 6°3′19″E) and has 21 member states. Israel is the first (and currently only) non-European country granted full membership. The term CERN is also used to refer to the laboratory, which in 2013 had 2,513 staff members, and hosted some 12,313 fellows, associates, apprentices as well as visiting scientists and engineers representing 608 universities and research facilities.

#5783. The Non-Aligned Movement (NAM) is a group of states which are not formally aligned with or against any major power bloc. As of 2012, the movement has 120 members. When and where was it founded?

#5784. The Shanghai Cooperation Organisation is a Eurasian political, economic and military organisation which was founded in 2001 in Shanghai by the leaders of China, Kazakhstan, Kyrgyzstan, Russia, Tajikistan, and Uzbekistan. These countries, except for Uzbekistan had been members of the Shanghai Five, founded in 1996; after the inclusion of Uzbekistan in 2001, the members renamed the organisation. On July 10, 2015, the SCO decided to admit India and Pakistan as full members, and they are expected to join by 2016. Where is the Headquarters of SCO?
