Water contracts as it cools, similar to all other liquids, until it reaches a temperature of around 4 degrees Celsius, at which the point it expands and starts to form into crystals, expanding around 9 percent.
The velocity of a body was observed to be constant throughout five minutes of its motion. Determine its acceleration during this interval?
What is Curie constant and Curies law? Curie constant: C (P. Curie): The characteristic constant, dependent on the material in question that points out the proportionality among its susceptibility
Joule: J (after J.P. Joule, 1818-1889): The derived SI unit of energy stated as the quantity of work done by moving an object via a distance of 1 m by exerting a force of 1 N; it therefore has units of N m.
Carnot's theorem (S. Carnot): The theorem that states that no engine operating between the two temperatures can be more proficient than a reversible engine.
Siemens: S (after E.W. von Siemens, 1816-1892): The derived SI unit of an electrical conductance equivalent to the conductance of an element which has a resistance of 1 O [ohm]; this has units of O-1.
Cosmic censorship conjecture (R. Penrose, 1979): The conjecture, so far wholly undemonstrated in the context of general relativity, that all singularities (that is with the possible exception of the big bang singularity) are attended
Planck equation: The quantum mechanical equation associating to the energy of a photon E to its frequency nu: E = h nu.
What do you mean by the term neutral buoyancy? Briefly illustrate it.
Describe why is heavy water employed as a moderator? Illustrate.
Kirchhoff's laws (G.R. Kirchhoff) Kirchhoff's first laws: An incandescent solid or gas in high pressure will generate a continuous spectrum.
