That's a spherical surface, with the charge at the center of the sphere.
There seems to be a spelling error in your query. If you are referring to "allele frequency," it is a measure of the relative frequency of an allele within a population's gene pool. It is expressed as a proportion or percentage of all alleles at a particular genetic locus.
Seems to me it has to be the line that passes through the mid-point of the line joining the charges, and perpendicular to it. It would be a line with slope = -1 / (slope of line joining the charges) and passing through the point that's (d/2) distant from both charges.
In science, direction refers to the orientation of an object or a vector in space. It is a dimension that specifies a straight path along which something moves, points, or faces. Direction can be described using coordinates, angles, or reference points to indicate position and movement.
The path of a moving point is the trajectory or route that the point follows as it travels through space or along a surface. The path can be straight, curved, circular, or any other shape, depending on the motion of the point. It is typically described by its position coordinates as a function of time.
Wavefront is the locus (a line, or, in a wave propagating in 3 dimensions, a surface) of points having the same phase. Thus wavefront should be obtained after each period(duration of one cycle) of a signal. And wavefront is tangent to the signal at each of those pints. this concludes that: distance between two wavefront is lambda(wavelength of a signal).
The locus of a moving point so that it is equidistant from another fixed point (i.e. the distance between them is always constant) is a circle.
A line is the locus of points such that the gradient (slope) between that point and one fixed point in the plane is a constant. Technically, that definition does not include a vertical line because its gradient is not defined! You could get around that this by requiring that either the gradient is a constant or, if it is undefined, then the inverse gradient (dx/dy) is constant.
Each of those is a locus of constant latitude.
It is the locus of points such that the sum of their distance from two distinct fixed points is a constant.
That's a sphere whose radius is the constant equal distance.
I assume that you are asking about the definition of a circle. A circle is a locus of points in a plane that are at a constant distance from a fixed point.
It is the locus of a point such that the sum of its distance from two (distinct) fixed points is a constant. So, given two fixed points, F1 and F2, an ellipse is the locus of the point P such that PF1 + PF2 is a constant. That would be an ellipsoid, a 3 dimensional thing. The 2 distances have to be measured in a fixed (2 dimensional) plane.
The plural form of locus is loci.
The specific term is gene locus. If the exact location is known then there is more specific terminology that refers to the chromosome number whether the locus is on the short (p) or long (q) arm of the chromosome and it's specific location based on band and sub-band location.
The plural of locus is loci.
Plural forn of locus is loci.
when you combine locus of control and proactivity you get
