Answer:
Explanation:
12000 mega watts = 12000 x 10⁶ watt.
rate of energy conversion is only 10 % so solar power required
= 12000 x 10⁶ x 100 / 10
= 12 x 10¹⁰ watt .
one square meter provides 169 watts
area required to obtain 12 x 10¹⁰ watt = 12 x 10¹⁰ / 169 m²
= .071 x 10¹⁰ m²
= 71 x 10⁷ m² . Ans.
Answer:
3.87 or 3.9 mg
Explanation:
