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).
Scientists continue to pursue a unified theory of these forces. 1  Gravitation is the force that acts between masses. All particles experience the force of gravity. 2  The electromagnetic force acts between electrical charges and the mediating particle is the photon.
