Electrons are found select one: a. orbiting around the nucleus in circular paths. b. moving around the nucleus in concentric clouds. c. in individual clouds (one electron per cloud) that orbit the nucleus. d. in fixed positions on the rings that surround the nucleus.

Along, straight wire with 3.0 a current flowing through it produces magnetic field strength 1.0 t at its surface. if the wire has a radius r, where within the wire is the field strength equal to 36.0% of the field strength at the surface of the wire? assume that the current density is uniform throughout the wire

The electric potential v is constant everywhere within a certain region of space. which statement below is true? the choices are: the electric field is also constant (but not zero) within the region. a charged particle placed within the region will experience an electric force. the electric field is zero everywhere within the region. the electric field varies from place to place within the region.
