Which levels of government establish and implement educational requirements for minors

Consider a plane source in an infinite uniform medium, isotropically emitting s monoenergetic neutrons (energy-e) per cm 2 per s. the uncollided scalar flux, q , in this medium is a function of the perpendicular distance (call it x) from the plane source. find an expression for, (x) . [hint: first find the angular flux from the integral equation, then integrate it over angle.]

Agrindstone in the shape of solid disk with diameter 0.42 m and a mass of 50.0 kg is rotating at 750.0 rev/min. you press an axe against the rim with a normal force of 160 n and the grindstone comes to rest in 7.8 seconds. find the coefficient of kinetic friction between the axe and the grindstone. there is negligible friction in the bearings.

Which magnetic property best describes a magnet’s ability to act at a distance? magnets are dipolar. magnets attract only certain objects. magnets have magnetic fields. magnets can transfer their properties to certain materials.
