During the rock cycle, sedimentary rocks are returned to the Earth's interior and become metamorphic rocks through metamorphism.
Metamorphic rocks can then move even deeper into the Earth's interior and melt into magma.
What phenomenon is responsible for moving sedimentary and metamorphic rock into the Earth's interior?
A. plate tectonics
B. infiltration
C. condensation
D. the carbon cycle

Answer:
Explanation:
Energy density in magnetic field is given as;
where;
B is the magnetic field strength
Energy density of electric field
where;
E is electric field strength
Take the ratio of the two fields energy density
But, Electric field potential, V = E x L = IR (I is current and R is resistance)
Now replace E x L with IR
Also, B = μ₀I / 2πr, substitute this value in the above equation
cancel out the current "I" and factor out μ₀
Finally, the equation becomes;
Therefore, the correct option is (d) μ₀/ϵ₀ (L /R 2πr)²
