The amount of energy required to remove the most loosely bound electron from a gaseous atom in its ground state is called its first ionization energy (IE 1 ). The first ionization energy for an element, X, is the energy required to form a cation with +1 charge: X(g) X+ (g) +e− IE1 X ( g) X + ( g) + e − IE 1 ...

WebApr 5, 2024 · The first option involves fiber and yarn. Separating the different types of fiber and yarn is essential to handle the shade variation. Techniques of the classical calculus of variations can be applied to examine the energy functional E. The first variation of energy is defined in local coordinates by δ E ( γ ) ( φ ) = ∂ ∂ t t = 0 E ( γ + t φ ) . {\displaystyle \delta E(\gamma )(\varphi )=\left.{\frac {\partial }{\partial t}}\right _{t=0}E(\gamma +t\varphi ).} See more In geometry, a geodesic is a curve representing in some sense the shortest path (arc) between two points in a surface, or more generally in a Riemannian manifold. The term also has meaning in any See more A locally shortest path between two given points in a curved space, assumed to be a Riemannian manifold, can be defined by using the equation for the length of a curve (a function f from an open interval of R to the space), and then minimizing this length between the points … See more A geodesic on a smooth manifold M with an affine connection ∇ is defined as a curve γ(t) such that parallel transport along the curve preserves the tangent vector to the curve, so See more Geodesics serve as the basis to calculate: • geodesic airframes; see geodesic airframe or geodetic airframe • geodesic structures – for example geodesic domes See more In metric geometry, a geodesic is a curve which is everywhere locally a distance minimizer.
