Methane. The importance of methane in the greenhouse effect is its warming effect. Even though it occurs in lower concentrations than carbon dioxide, it produces 21 times as much warming as CO2.Methane accounts for 20% of the 'enhanced greenhouse effect'.ven though it occurs in lower concentrations than carbon dioxide, it produces 21 times as much warming as CO2.

On a horizontal surface, the gravitational force is equal to the object's weight, as is the normal force. But now the parallel force is the mass of the object * g * sin (theta), where g is the acceleration due to gravity (9.8 m/s^2), and theta is the angle of the inclined plane. For the perpendicular vector, the magnitude is the mass of the object * g * cos (theta).
Forces associated with solids. Normal (N, Fn) The force between two solids in contact that prevents them from occupying the same space. The normal force is directed perpendicular to the surface. A normal in mathematics is a line perpendicular to a planar curve or surface; thus the name normal force. Friction (Æ, F Æ)
