The right answer for the question that is being asked and shown above is that: "A.tectonic activity concentrated in certain areas." A piece of evidence did Alfred Wegener use to develop the theory of continental drift is that <span>A.tectonic activity concentrated in certain areas</span>

Answer:

Explanation:
Our values are,

We have all the values to apply the law of linear momentum, however, it is necessary to define the two lines in which the study will be carried out. Being an intersection the vehicle of mass m_1 approaches through the X axis, while the vehicle of mass m_2 approaches by the y axis. In the collision equation on the X axis, we despise the velocity of object 2, since it does not come in this direction.

For the particular case on the Y axis, we do the same with the speed of object 1.

By taking a final velocity as a component, we can obtain the angle between the two by relating the equations through the tangent

Replacing in any of the two functions, given above, we will find the final speed after the collision,
