In physical terms, the divergence of a three-dimensional vector field is the extent to which the vector field flow behaves like a source or a sink at a given point. It is a local measure of its outgoingnessâthe extent to which there is more exiting an infinitesimal region of space than entering it.ore rigorously, the divergence of a vector field F at a point p is defined as the limit of the net flow of F across the smooth boundary of a three-dimensional region V divided by the volume of V as V shrinks to p. Formally,
Cub Scouting is part of the Scouting program of the Boy Scouts of America (BSA), available to boys from first through fifth grade, or 7 to 11Â½ years of age and their families. Its membership is the largest of the three BSA divisions (Cub Scouting, Boy Scouting, and Venturing).
The Boy Scout program is for youth who are 11 years old, are at least ten years old and have finished the fifth grade, or are at least ten years old and have earned the Arrow of Light rank as a Cub Scout. The purpose of Boy Scouting is the same as it is for Cub Scouts: to help youth grow into good citizens who are strong in character and personally fit.
