Awire of circular cross-section carries current density that is not uniform but varies with distance from the center as j(r) = a r / r, for radius r in the range 0 < r < r. here, a is a constant with units amperes per square meter, and the radius of the wire is r = 8.1 mm. find an expression for the magnetic field outside of the wire, for r > r.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

3.2x10^7

c) up

hope this

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
