Asolar panel measures 0.57 m by 1.3 m. in direct sunlight, the panel delivers 6.6 a at 6 v. if the intensity of sunlight is 300 w/m2, what is the efficiency, as a percentage, of the solar panel in converting solar energy into electrical energy?

efficiency of solar panel is 18%

Explanation:

Energy received by the sunlight is given as

here we know the dimensions of the plate as

now we have

now the power received by the sun light is given as

now the output power due to solar panel is given as

now the efficiency is given as

the results is a decrease in air temperature with an increase of altitude.

explanation:

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.
