Suppose a point charge is located at the center of a spherical surface. The electric field at the surface of the sphere and the total flux through the sphere are determined. Now the radius of the sphere is halved. What happens to the flux through the sphere and the magnitude of the ...

The paper gives an exact formula for determining the intensity of an optical field at the center of a spherical particle of arbitrary radius obtained by evaluating an indeterminate form of the 0/0 type of Mie theory for the electric‐field components at the center of the sphere. This formula...
This study determines the ideal penetration limits for heating the center of a volume of muscle tissue according to this constraint. First, it is shown that the most efficiently heated volume is a sphere. Then, using both a diffraction integral formulation and a spherical harmonic modal approach,...

摘要: An explicit formula for the time required for the center of an initially uniformly heated sphere to attain a given temperature due to thermal diffusion is given in terms of the radius and a temperature parameter.关键词: Theoretical or Mathematical/ heat conduction/ radial heat flow ...
The meaning of CENTER is the point around which a circle or sphere is described; broadly : a point that is related to a geometrical figure in such a way that for any point on the figure there is another point on the figure such that a straight line joini
STEM education – the combined approaches of inquiry, project-based learning, integrated curriculum, and career awareness – prepares students for the future.
center of mass, the point at which all the mass of a body may be considered to be concentrated in analyzing its motion. The center of mass of a sphere of uniform density coincides with the center of the sphere. The center of mass of a body need not be
Center of gravity, in physics, an imaginary point in a body of matter where, for convenience in certain calculations, the total weight of the body may be thought to be concentrated. In a uniform gravitational field, the center of gravity is identical to
