By what distance, x2, should the second child compress the spring so that the marble lands in the middle of the box? (assume that height of the box is negligible, so that there is no chance that the marble will hit the side of the box before it lands in the bottom.)express the distance in terms ofm, k,g, h, andd.

Idk bro sorry  lava is hotter then magma but im  not sure about it alll

The reason why i feel that the theory of plate tectonics is correct because scientists have found dinosaur bones of the same species in africa, asia, and in the americas. which means that they must have been together at one point in time. plate tectonics is also how the hawaiian islands were formed. as the plate hawaii is on was moving north west, magma would melt through the sea bottom and hardening. forming into the island chain. plate tectonics also explains the mariana trench. two plates were moving away from each other and made a giant crack in the ocean floor running 2,550 kilometers (1,500 miles)  long.
