D It is released or absorbed.
Explanation:
To form a solution, energy is absorbed or released in the process.
A solution is a substance made up of solute dissolved in a solvent. The solute is the dissolved substance where as the solvent is the dissolving medium.
- To form a solution, solutes are dissolved.
- In this dissolution reaction, energy is used to break bonds within the solute to bring them in contact with the solvent.
- The combination of the solute with the solvent is a bond formation process.
- Bond formation is an exothermic process in which energy is released.
- Bond breaking process is endothermic in which energy is absorbed.
- To form solutions, bonds are formed and broken.

Since an alpha particle has 2 protons and no negative particles (electrons) to balance the net charge, its charge is
Q=2(1.6e-19)=3.2e-19C.
The force on a charged particle is F=QE so
(3.2e-19C)(600N/C)=1.92e-16N
That's a weird graph, but judging from the units the acceleration is the slope of the graph.
a = (0.8 - 0.3)/(0.16 - 0.055) = 4.76 m/s²
<span>D. sill
A sill forms when hot magma squeezes between layers of rock to form a hardened sheet of rock. A sill is basically a tabular sheet intrusion between old layers of sedimentary rock, volcanic beds, or in the direction of foliation inherent in metamorphic rock. The word sill means a concordant intrusive sheet.</span>
