In the formation of mountain ranges and all other landforms, there is always a cycle involved. As one mountain comes up, another land gets pushed down into the hot mantle, where the rock will melt. Due to convection currents, the tectonic plates move and their boundaries cause them to interact with each other. As mountain ranges are formed, other land gets pushed up forming what we know are mountains, with rising magma from other parts of the world solidifying creating new rock to fill the empty space.
21+10=31 because you can see that 21 and 10 are in metres while 12 is in seconds so 21+10=31 is the answer.
Answer: 44 N/m
Explanation:
Finding the interatomic spring stiffness
Because in our model all the bonds are assumed to be the same, the interatomic spring stiffness ks, interatomic is determined by adding the springs . The details of that addition are below, but the final result is that the interatomic spring stiffness is related to the spring stiffness of the wire like so:
