The amount of solar power reaching the atmosphere on an area equivalent to the area of a soccer field, 73meters × 100 meters, is about:(Hint: The solar constant is about 1,368 W/m^2)A. 5.3 WB. 1.368 × 10^3 WC. 10 × 10^6 WD. 7.3 × 10^7 W

Respuesta :

ANSWER :

C. 10.0 x 10^6

EXPLANATION :

The amount of solar power is equivalent to the area of the field.

The area of the field is :

[tex]73m\times100m=7300m^2[/tex]

Multiply this area by the solar constant :

[tex]7300\cancel{m^2}\times\frac{1368W}{\cancel{m^2}}=9,986,400\quad W[/tex]

When written in scientific notation :

[tex]\begin{gathered} 9986400\rightarrow9.99\times10^6 \\ or \\ 10.0\times10^6\quad W \end{gathered}[/tex]
