For vibrational states, the boltzmann equation can be written as n1 n0 = e − δe kt, where n0 and n1 are the populations of the lower and higher energy states, respectively, δe is the energy difference between states, k is boltzman’s constant, and t is the temperature in kelvins. for temperatures of 15 °c and 50 °c, calculate the ratios of the intensities of the anti-stokes and stokes lines for ccl4 at (a) 218 cm-1 , (b) 459 cm-1 , and (c) 790 cm-1 . for each temperature and raman shift, calculate how much more intense the stokes line is compared to the anti-stokes line. room temperature is 298k

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.

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.
