The sun transfers energy to the earth by radiation at a rate of approximately 1.00 kw per square meter of surface.

a. if this energy could be collected and converted to electrical energy with 24 efficiency how large an area (in square kilometers) would be required to collect the electrical energy used by the united states? ( joules per year).

b. if the solar collectors were arranged in a square array, what would be the length of its sides in kilometers and in miles?

with all parts

1320336992.2512 m²

1320.33 kilometers or 509.79 miles

Explanation:

Energy transferred by the sun

Energy required by the United States is (assumed)

Power

Area

Area of the solar collector would be 1320336992.2512 m²

Converting to km²

Converting to mi²

Each side of the square would be 1320.33 kilometers or 509.79 miles

the answer is mosques. they are an important part of islamic culture.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
