The distance traveled over a period of time is called:

The geological theory that states that pieces of earth's lithosphere are in constant slow motion is the theory of plate tectonics.

The answer is 4f======since electrostatic force is given by    we let f be the electrostatic force when  r = 1 m    if we let  denote the electrostatic force when the distance is decreased so that r = 0.5m, then    we established earlier that f = kq₁q₂. therefore    the force will now be 4f.

Ray 2 should cross through the focal point on the right side of the lens.

The correct answer is  ait's a process by which rocks and minerals undergo in their composition^o^
