What is the meaning of virial?

: half the product of the stress due to the attraction or repulsion between two particles in space times the distance between them or in the case of more than two particles half the sum of such products taken for the entire system.

What does Veral mean?

Veral is a village in Ratnagiri district, Maharashtra state in Western India. The 2011 Census of India recorded a total of 3,171 residents in the village. Veral’s geographical area is approximately 503 hectares (1,240 acres).

What does the virial theorem say?

Statement of the Virial Theorem: For the n point particles bound together into a system the time average of the kinetic energy of the particles, Σ½mivi², plus one half of the time average of ΣFi·ri is equal to zero.

What is a virial radius?

The virial radius rvir is conventionally defined as the radius within which the mean density is 200 times the background density. Matter accretion is in general quite well described within the approximation of the Spherical Collapse Model.

When a man is virile?

You’ll often hear the word virile referring to a manly, powerful man, because the word means having physical strength and other typical masculine qualities. When you think of a virile man, you imagine a tough, strong guy who’s full of energy, vigor, and sexual potency.

When can you use virial theorem?

The virial theorem has a wide range of applications in astrophysics, from the formation of stars (in which case the bodies of the system are the atoms of the gas) to the formation of the largest structures in the universe, the clusters of galaxies.

Where does virial theorem not apply?

Perhaps the most important limitation is that virial theorems do not apply to particles that are not in a bounded system. In particular it does not apply to the particles of an explosion.

What is the virial radius of the Milky Way?

In this two-component model, the Milky Way’s virial radius and mass are rvir ~= 200 kpc and Mvir ~= 1.5 × 1012Msolar.

What is a fertile man called?

Virile means “marked by strength or force”. Virility is commonly associated with vigour, health, sturdiness, and constitution, especially in the fathering of children. In this last sense, virility is to men as fertility is to women.

What is the meaning of the word virial?

(mechanics) Of or pertaining to the interactive forces between molecules or particles. (mechanics) Half of the product of the stress of attraction or repulsion with the distance between two particles. Common misspelling of viral.

Which is the correct definition of the virial coefficient?

Definition of virial coefficient. : one of the coefficients in a series of terms involving inverse powers of specific volume whose sum represents the product of specific volume by pressure for a pure gas useful form of the equation of state of a real gas is pv = A + B/v + C/v2 + …, where A, B, C, etc.

What do you mean by a word wall?

What is a word wall? A word wall is just that—a wall dedicated to displaying high frequency words (these could be sight words or words that are used a lot in your class) that are important for your students to know and use. In early elementary classrooms, these are words that children are learning to read and write.

Which is the simple form of the virial theorem?

Virial theorem. If the force between any two particles of the system results from a potential energy V(r) = αrn that is proportional to some power n of the interparticle distance r, the virial theorem takes the simple form Thus, twice the average total kinetic energy ⟨T⟩ equals n times the average total potential energy ⟨VTOT⟩.
