The answer to the question is
<span>PE = W = 1/2 (kx^2)
16.2  = </span>1/2 (k(0.30)^2)
k = 360 J/m^2
        
             
        
        
        
<h3><u>Answer;</u></h3>
Mid-ocean ridges 
<h3><u>Explanation</u>;</h3>
- Sea-floor spreading is the process by which molten material adds new oceanic crust to the ocean floor.
- Mid-ocean ridge is an undersea mountain chain where new ocean floor is produced at a divergent plate boundary.
- Mid ocean ridge occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.
 
        
        
        
Water displacement. You fill a graduated cylinder with an amount of water, place the object inside the graduated cylinder, and then measure the new water level. The change in volume of the water is the volume of the object, assuming the object was completely submerged. 
        
             
        
        
        
R2^ 2 / R1 ^2 = g1 / g2 = 38 
<span>R2 = R1 x √38 = 6.1644* R1 </span>
<span>R2 = 6.1644 x 6378 000 = 39316632.5 m</span>
