What is DMS? Sonography can be used to examine many parts of the body, such as the abdomen, breasts, female reproductive system, prostate, heart, and blood vessels. Sonography is increasingly being used in the detection and treatment of heart disease, heart attack, and vascular disease that can lead to stroke.
For other uses, see Mass action (disambiguation) . In chemistry, the law of mass action is a mathematical model that explains and predicts behaviours of solutions in dynamic equilibrium. Simply put, it states that the rate of a chemical reaction is proportional to the product of the masses of the reactants.
Newton's law of gravity is the statement that the force by which a particle of mass M acts on a particle of mass m has magnitude GMm/r2 and direction from m to M. Newton's theory of gravity is the framework that contains this law and everything else you need to calculate the motion of particles influenced by this law.
