Answer 1

Answer:

Hey! This is your answer

Explanation:

1. The magnetic moment of a magnet is a quantity that determines the torque it will experience in an externalmagnetic field. ... ITS SI UNIT IS -- 'In the metre–kilogram– second–ampere and SI systems, the specific unit for dipole moment is ampere-square metre.
2. A conducting sphere of radius 5 cm is charged to 15 uC. Another uncharged sphere of radius 10 cm is allowed to touch it for enough time. After the two are separated, the surface density of charge on the two spheres will be in the ratio?
3. The current density vector is defined as a vector whose magnitude is the electric current per cross-sectional area at a given point in space, its direction being that of the motion of the positive charges at this point. In SI base units, the electric current density is measured in amperes per square metre.
