Most of the long wave energy radiated from Earth and lost space on a cloudless night is 1. ultraviolet
2.infrared
3.visible light
4. gamma rays

2.infrared

Explanation:

Infrared radiation or infrared light is electromagnetic radiation.

Infrared A radiation (IR-A) accounts for almost a third of total solar radiation, while UVA and UVB radiation make up only seven percent of the total solar spectrum.

Of the total solar energy that reaches the Earth's surface, the largest part of the radiation of as much as 54-56 percent is IR radiation, 39 percent is visible light and about five to seven percent is UV radiation.

good thing- during decomposition the organic molecules in organic matter are broken down into simpler organic molecules that require further decomposition or into mineralised nutrients

bad thing- it can be harmful in crop productivity

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
