Radius in a sentence

Because water is incompressible and must remain within the confines of the bucket, this outward movement increases the depth of water at the larger radius, increasing the height of the surface at larger radius, and lowering it at smaller radius.

Note that the half-light radius includes stars in the outer part of the cluster that happen to lie along the line of sight, so theorists will also use the half-mass radius (r m )—the radius from the core that contains half the total mass of the cluster.

Recalculating Toomer's reconstructions with a 3600' radius i.e. the radius of the chord table in Ptolemy's Almagest, expressed in 'minutes' instead of 'degrees' generates Hipparchan-like ratios similar to those produced by a 3438' radius.

The equatorial radius of the star was estimated to be 2.03 solar radii, and the polar radius 1.63 solar radii—a 25% increase of the stellar radius from pole to equator.

These are the core radius (r c ), the half-light radius (r h ), and the tidal (or Jacobi) radius (r t ).

Namely, there aren't many planets that fulfill the definition of a "super-Earth," with a radius of one and a half to twice Earth's radius and a mass that is five to 10 times greater.

Among these is the theorem that a line contains at least two points, or that circles of the same radius whose centers are separated by that radius must intersect.

As a special case, one given circle may be a point located at one focus; since a point may be considered as a circle of zero radius, the other given circle—which is centered on the other focus—must have radius 2a.

Cylindrical projections The spherical approximation of Earth with radius a can be modelled by a smaller sphere of radius R, called the globe in this section.

For non-rotating black holes, the photon sphere has a radius 1.5 times the Schwarzschild radius.

For the sphere each normal section through a given point will be a circle of the same radius, the radius of the sphere.

However, the inner core of the Moon is small, with a radius of about convert or less, around 20% of the radius of the Moon.

If the radius of the bag is set to the radius of the nucleon, the bag model predicts a nucleon mass that is within 30% of the actual mass.

It had a large radius of curvature, or was composed of separate elements which, irrespective of their own radii of curvature, were arranged close to each other so that the outside ideal surface enveloping them has a large radius.

It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0.3% larger than the radius measured through the poles.

Likewise, if the radius of a sphere is doubled, its volume scales by eight, which is two (the ratio of the new to the old radius) to the power of three (the dimension that the sphere resides in).

Radioactivity can occur when the radius of a nucleus is large compared with the radius of the strong force, which only acts over distances on the order of 1 fm.

The cluster core radius is about 8 light years and tidal radius is about 43 light years.

The cross sectional radius of each Fresnel zone is the longest at the midpoint of the RF LoS, For practical applications, it is often useful to know the maximum radius of the first Fresnel zone.

The distance, or radius, of the electron from the field line at any time is known as its Larmor radius.
