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.

The interaction that does not take place due to field forces is the interaction between a pen and paper while you write.
<h3>What is the gravity law?</h3>
Gravity law is a well-established scientific theory that states objects can attract each other according to their masses.
This theory (gravity law) was developed by Sir Isaac Newton to explain the movement of objects.
In conclusion, the interaction that does not take place due to field forces is the interaction between a pen and paper while you write.

Answer:
a. the core will spin faster.
Explanation:
By law of conservation of angular momentum
(mvR)i= (mvR)f
m= mass of star
v= speed of star
R= radius of star
i= initial
f= final
since, size(R) of the star is reduced by factor of 10,000 and mass remains the same, the velocity must increase by the same factor to keep the angular momentum conserved.
Hence, a. the core will spin faster.
Use the inverse square law, thus if you move a distance of 3m away, the sound intensity decrease by 1/3^2= 1/9
Based on Newton's second law:
Force = mass x acceleration
For this problem: we have the mass = 1232 kg and the acceleration = 2 m/s^2
So, just substitute with the givens in the above equation to calculate the force as follows:
Force = 1232 x 2 = 2464 Newtons
