Absorbed solar radiation undergoes irreversible degradations, transferring from reservoir to another and ends up as what?
barxatty [35]

Answer:

Absorbed solar radiation undergoes irreversible degradations, transferring from reservoir to another converting from light energy to radiation energy.

Explanation:

The solar energy cycle functions in the following form:

  • Considering that 100% of energy is directed at earth.
  • When 100% light is incident on the Earth's surface about 6-7% of it is reflected back by the atmosphere into space.
  • 20% is reflected back by the clouds.
  • And about 4% is reflected back by Earth's surface.
  • 16% of solar energy is absorbed by the atmosphere, 3% is absorbed by clouds and 51% is absorbed by  land and ocean.
  • From the absorbed energy, 64% is radiated back to space from clouds and atmosphere and 6% is directly radiated back to space from earth.
  • From the radiated energy 15% is absorbed by the atmosphere and 23% is carried by the clouds and atmosphere through the latent heat in water vapor.

Therefore, absorbed solar radiation undergoes irreversible degradations, transferring from reservoir to another converting from light energy to radiation energy.

The magnitude of the electric current is inversely proportional to the _____ of the circuits in R2D2.
nika2105 [10]
According to Ohm's Law, the voltage is equal to the current multiplied by resistance. Presenting the law in equation form:

V = IR

This law still applies in an R2-D2 droid circuit. Rearranging the equation:

I = V/R

Hence, the current is inversely proportional to the resistance.

Why will light from the sun change the color of the cloth when the light from the desk lamp does not
mixas84 [53]

Answer:

Because the sun gives off a type of light that carries energy, and light from the desk lamp does not.

Explanation:

All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.
