Find the intensity of electromagnetic radiation at the surface of the sun (radius r=R=6.96×105kmr=R=6.96×105km). Ignore any scattering of the waves as they move radially outward from the center of the sun.

.

Explanation:

Intensity of the electromagnetic radiation is given by

where is the distance from the EM source (the center of the sun, in our case), and is the power output of the sun and it has the value

Since the radius of the sun in meters is , the intensity of the electromagnetic radiation at the surface of the sun is

The intensity of the electromagnetic radiation at the surface of the sun is .

momentum of soft ball three times less than baskey ball

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.
