Incoming solar radiation (light energy) is absorbed by the Earth's surface and converted to outgoing infrared radiation (heat en

An increase in temperature (Global warming) is observed. The solar radiation is transformed into heat energy absorbed by Earth's surface. In line with the law of conservation of energy, energy can only transition forms rather than disappear. If an increasing quantity of energy accumulates on Earth with minimal release, this imbalance in energy demand leads to a rise in temperature due to excessive heat absorption, largely a result of pollution from fossil fuel combustion releasing CO2 and other harmful emissions. Ordinarily, the residual solar energy would escape back into space, but CO2 and similar contaminants trap this heat, thus elevating Earth's temperature.

Softa [3030]

The overall force acting on the vehicle is zero

Explanation:

Let's evaluate the situation separately for the vertical direction and the horizontal direction along the slope.

Considering the direction perpendicular to the slope, two forces are in effect:

  • The weight component acting perpendicular to the slope, mgcos \theta, directed into the slope
  • The normal force N, directed outward from the slope

Equilibrium exists here, indicating the net force in this direction is zero.

Now let’s examine the parallel direction to the slope. We have two forces present:

  • The weight component aligned with the slope, mgsin \theta, directed down the slope
  • The frictional force F_f, acting up the slope

The car moves at a constant speed in this direction, indicating that its acceleration is zero.

a=0

Thus, according to Newton's second law,

F=ma

implying the net force is zero:

F=0
