Answer:

<u>Longwave terrestrial radiation at the night time, in the of infrared rays.</u>

Explanation:

  • As the short wave solar radiation or the visible light containing lots of energy the longwave radiation of the earth contains infrared that has less energy. As the solar radiation that enters our atmosphere in the form of UV rays, and sun emits these short waves as they are extremely hot and hence have lots of energy to give off.
  • As parts of incoming solar are absorbed by the earth's surface features and rest of is reflected into the atmosphere by cloud cover and the energy that falls on the ground is reradiated back to the sun as the earth is cooler at night and less energy is given off.
  • Hence the atmosphere tires to balance the incoming energy from the sun in the form of a heat budget and a greenhouse effect.

In the diagram below, OL is perpendicular to DX.<br>Pro<br>No 13<br>Tea<br>Find the length of OX​
lubasha [3.4K]

Answer:

Line OX = 7.09

Explanation:

The question is incomplete. Find attached the complete question.

SOLUTION

Given:

Line OL is perpendicular to DX

Line DX = 13

Line PO = the hypotenuse of the larger triangle

Line PO = 10

Line BO = hypotenuse of smaller triangle

Line BO = 12

To find length of line OX, we would apply rule of similar and congruent triangles.

∆DPO = ∆XBO

<POD = <BOX

Line DP is parallel to line XB

Since length of side DX = 13

Side DX = side DO + side OX

Let side DO = x

Side OX = 13-x

(Adj of ∆DPO)/(Adj of ∆XBO) = hyp of ∆DPO/hyp of ∆XBO

DO/OX = PO/BO

x/ (13-x) = 10/12

12x = 10(13-x)

12x = 130-10x

12x +10x = 130

22x = 130

x = 130/22 = 65/11

x is approximately = 5.91

Therefore line OX = 13 - 5.91

Line OX = 7.09
