The necessity of laying out all of the leads in a basically radial pattern in a single plane from the die perimeter to two rows on the periphery of the package is the main reason that DIP packages with higher lead counts must have wider spacing between the lead rows, and it effectively limits the number of leads which a practical DIP package may have.

Also encircling the basin is a pattern of radial grooves called the " Imbrium Sculpture ", which have been interpreted as furrows cut in the Moon's surface by large projectiles blasted out of the basin at low angles, causing them to skim across the lunar surface ploughing out these features.

Furthermore, a Moon-wide pattern of faults which run both radial to and concentric to the Imbrium basin were thought to have been formed by the Imbrium impact ; the event literally shattered the Moon's entire lithosphere.

# The Slater-type orbital ( STO ) is a form without radial nodes but decays from the nucleus as does the hydrogen-like orbital.

where m and n are nonnegative integers with, is the azimuthal angle in radians, and is the normalized radial distance.

For the case of an object that is small compared with the radial distance to its axis of rotation, such as a tin can swinging from a long string or a planet orbiting in a circle around the Sun, the angular momentum can be expressed as its linear momentum,, crossed by its position from the origin, r. Thus, the angular momentum L of a particle with respect to some point of origin is

Because of the cross product, L is a pseudovector perpendicular to both the radial vector r and the momentum vector p and it is assigned a sign by the right-hand rule.

Angular momenta of a classical object .< p > Left: intrinsic " spin " angular momentum S is really orbital angular momentum of the object at every point ,</ p >< p > right: extrinsic orbital angular momentum L about an axis ,</ p >< p > top: the moment of inertia tensor | moment of inertia tensor I and angular velocity ω ( L is not always parallel to ω )</ p >< p > bottom: momentum p and it's radial position r from the axis .</ p > The total angular momentum ( spin + orbital ) is J.

* Some curves that seem simple, such as the circle, cannot be described exactly by a Bézier or piecewise Bézier curve ; though a four-piece cubic Bézier curve can approximate a circle ( see Bézier spline ), with a maximum radial error of less than one part in a thousand, when each inner control point ( or offline point ) is the distance horizontally or vertically from an outer control point on a unit circle.

The height of the water h = h ( r ) is a function of the radial distance r from the axis of rotation Ω, and the aim is to determine this function.

That the Earth is itself an oblate spheroid, bulging at the equator where the radial distance and hence the centrifugal force is larger, is taken as one of the evidences for its absolute rotation.

In the case of a central force, relative to the origin of the polar coordinate system, can be replaced by, meaning the entire force is the component in the radial direction.

In such a frame, the observed is zero and alone is treated as the acceleration: so in the equation of motion, the term is " reincarnated on the force side of the equation ( with opposite signs, of course ) as the centrifugal force mω < sup > 2 </ sup > r in the radial equation ": The " reincarnation " on the force side of the equation is necessary because, without this force term, observers in the rotating frame would find they could not predict the motion correctly.

When the angular velocity of this co-rotating frame is not constant, that is, for non-circular orbits, other fictitious forces — the Coriolis force and the Euler force — will arise, but can be ignored since they will cancel each other, yielding a net zero acceleration transverse to the moving radial vector, as required by the starting assumption that the vector co-rotates with the planet.

The ship was a Waco biplane, one of the first two of its type to be fitted with the air cooled, 225/hp Wright radial engine known as the Whirlwind.

When compared with the concept map ( which was developed by learning experts in the 1970s ) the structure of a mind map is a similar radial, but is simplified by having one central key word.

In one system which is usual in physics ( r, θ, φ ) gives the radial distance, polar angle, and azimuthal angle, whereas in another system used in many mathematics books ( r, θ, φ ) gives the radial distance, azimuthal angle, and polar angle.

The wave equation is unchanged under rotations of the spatial coordinates, because the Laplacian operator is invariant under rotation, and therefore one may expect to find solutions that depend only on the radial distance from a given point.
