Answer:

206.8965517 n

Explanation:

First, we need to see that 60:29 is 2.078965517:1. Then we need to multiply the energy put 29 cm from the fulcrum by 2.078965517, giving us the end result of our answer.

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.

An object is dropped from 26 feet below the tip of the pinnacle atop a 702 ft tall building. The height h of the object after t
Dimas [21]

Answer:

6.5 seconds.

Explanation:

Given: h=-16t²+679

When the object reaches the ground, h=0.

∴ 0=-16t²+679

collecting like terms,

⇒ 16t²=679

Dividing both side of the equation by the coefficient of t² i.e 16

⇒ 16t²/16 = 679/16

⇒ t² = 42.25

taking the square root of both side of the equation.

⇒ √t² =√42.25

⇒ t = 6.5 seconds.
