Climate of Brazil the summer and minimum in the winter. More than 70% of the total rain that is accumulated during the year falls from November to March. The winter is excessively dry, because the rains are very rare. Climate of Brazil The climate in Brazil varies considerably mostly from tropical north (the equator traverses the mouth of the Amazon) to temperate zones south of the Tropic of Capricorn (23°26' S latitude). Temperatures below the equator are high, averaging above , but not reaching the summer extremes of up to in the temperate zones. There is little seasonal variation near the equator, although
Degrees of freedom (physics and chemistry) system is the sum of the average energies associated with each of the degrees of freedom: A degree of freedom is quadratic if the energy terms associated with this degree of freedom can be written as where is a linear combination of other quadratic degrees of freedom. example: if and are two degrees of freedom, and is the associated energy: For example, in Newtonian mechanics, the dynamics of a system of quadratic degrees of freedom are controlled by a set of homogeneous linear differential equations with constant coefficients. are quadratic and independent degrees of freedom if the energy associated with
