in a stably stratified ocean, water that is displaced vertically from its equilibrium position will feel a restoring force that is proportional to the magnitude of the displacement. associated with this restoring force is a natural frequency of oscillation known as the brunt-vasiala frequency az where n is the brunt-vaisala frequency, g is the acceleration due to gravity, ρ is the density of the displaced water. derive this equation for n2. you could start by writing down the one-dimensional equation for motion for the vertical displacement of a water element displacement downward in a density stratified fluid and recall equations for simple harmonic motion.

glen is correct.

step-by-step explanation:

glen is correct because when you multiply 4 * 2 = 8.

and 4 * 3 = 12.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
