The Intensity of solar radiation at the Earth's orbit is 1370 W/m2. However, because of the atmosphere, the curvature of the Earth, and rotation (night and day), the actual intensity at the Earth's surface is much lower. At this moment, let us assume the intensity of solar radiation is 750 W/m2. You have installed solar panels on your roof to convert the sunlight to electricity. A) If the area of your solar panels is 4 m2, How much power is incident on your array? Watts Submit Answer Tries 0/2 B) Unfortunately, solar panels are only about 20% efficent... Only 1/5 of the light is converted to electricity. This being the case, how much electrical power are you actually producing for your home at this moment?

A. Power incident on panel = 3000W

B. Electrical power generated = 600W

Explanation:

Actual solar intensity I = 750W/m2

A) if area A of panel = 4m2, then,

Power incident on panel = I x A

P = 750 x 4 = 3000W

B) if panel efficiency is 20%,

Then,

Power generates = 0.2 x 3000 = 600W of electricity.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
