Acircular plastic rod with uniform charge q produces an electric field of magnitude e at the center of curvature (at the origin). in figs. 22-28b, c, and d, more circular rods, each with identical uniform charges q, are added until the circle is complete. a fth arrangement (which would be labeled e. is like that in d except the rod in the fourth quadrant has charge q. rank the ve arrangements according to the magnitude of the electric eld at the center of curvature, greatest rst

empty space could also be a simple vacuum

2b2t

explanation:

2b2t

well, their are quite a few differences !

explanation:

first difference is a main sequence star is made of carbon, while a neutron star is made of neutrons. another difference is a main sequence star still has hydrogen to burn, while a neutron star is a remnant of a supernova.

a main sequence star is what’s left over from a low-mass star death, while a neutron star is what’s left from the death of a high-mass star. main sequence star and a neutron star are considered the same thing, except a main sequence star spins.
