The mean distance between the Earth and the Sun is 1.50

The mean distance between the Earth and the Sun is 1.50

Solutions

Expert Solution

Given :

.

            Intensity (I) = 1390 W /m2

.

            Distance (r) = 1.50 1011 m

.

We know that :

.

            Power (P)   =  Intensity * Surface area

.

                                = I * 4?r2       ( surface area ofsphere )

.

                                = 1390 W /m2 * 4 * 3.14 * (1.501011 )2

.

                                 =   ----------- W
