Which statement is true about the rock cycle? a- Once a metamorphic rock is formed, it will always be a metamorphic rock.

b- Heat and pressure that are applied to an igneous rock eventually creates a metamorphic rock.

c- Sedimentation is the primary process that converts a sedimentary rock into a metamorphic rock.

d-When magma pours out on the Earth's surface, it forms metamorphic rock.

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.

Answerit is comparative because this experiment is comparing the results of the volume at minimal pressure and then increases it; ; ;

The inference is supported by evidence in the graph is this is an exothermic reaction where the total release of energy equals a + c.

The correct answer is waves
