Answer:
The mmf required is 
×
A
Explanation:
The Magnetomotive force (mmf) is given by the formula below
where 
is the Magnetomotive force (mmf)
is the Magnetic field strength
is the magnetic length
The magnetic permeability μ is given by
μ = 
Where 
is the Magnetic flux density
and is the Magnetic field strength
From the question,
= 1.2Wb/m^2
μ = 1600m
From μ =
∴
μ
× 
A/m
Now, for the Magnetomotive force (mmf)
From the question
= 1.5 m
∴ 
× × 
×
Hence, The mmf required is × A
Metal ores
Explanation:
in an area where subduction has occurred in times past, metal ores are likely to be found.
Metallic ores find subduction zone regions very favorable to crystallize out of a magma.
- Ores have different modes of formation.
- Typically, they are found in hydrothermal vents and black smokers of igneous intrusives.
- These are igneous terrains where metallic sulfides and other minerals crystallize out of magmatic body.
- Metals in magma usually have large sizes and do not partition easily in the melt.
At a subduction zone, partial melting of the subducting plate forces magma into nearby country rock as an intrusive and to the ocean floor where they form black smokers.

conservation of angular momentum. it will tend to keep spinning in same direction ... in linear case, a body would keep going until a force altered its motion
Answer:
frictonal force due to the surface of irregularities
I believe that since Kepler focused his studies the rotation of the planets, and the stars, that he is the one who developed the law, which is called the first law of planetary motion.
