The excavation of gold from the deep oceanic vents made possible from the Atlantic and north Pacific oceans. Approximately 100 metric million tons of gold has been excavated from these oceans. Also, the undissolved gold in the seafloor has also been excavated. But currently, gold mining from the sea floor and the deep oceanic crust is not considered as efficient mining process.
When three or more coplanar forces are acting at a point and the vector diagram closes, there is no resultant. The forces acting at the point are in equilibrium.
