Answer:
(1.9756, -2.1951)
Explanation:
The center of mass equation is: 
= 
, where m represents the masses and x represents the position.
In order to find the coordinates of the center of mass, we need to use this equation for both the x-values and the y-values.
<u>x-values:</u>
<u /> = = 
= 
= 
= 1.9756
<u>y-values:</u>
<u />
= 
= 
= 
= 
= -2.1951
<u>center of mass:</u>
(1.9756, -2.1951)
Then, it would continue the motion in direction of resultant force...
I think the amount of force will decrease and the amount of work will increase
The correct answer is - It is the part of the ocean where new crusts are formed.
The place marked with A on the map is the place in the ocean where the new crust is formed. That is a place where there's a divergent plate boundary, or rather a place where the tectonic plates are moving away from one another. The gap and cracks left between them are easy target for the magma from the mantle to penetrate towards the surface. As the magma reaches the ocean floor it starts to cool off very quickly, creating new crust, and slowly making a very large underwater mountain range known as mid-ocean ridge.
