Energy from the Sun arrives at the top of the Earth's atmosphere with an intensity of 1.1 kW/m2 . How long does it take for 1.91
×109 J to arrive on an area of 1 m2 ?
1 answer:
Answer:
1.736 × 10⁶
Explanation:
Data provided in the question:
Intensity of the energy received from the sun = 1.1 kW/m² = 1.1 × 10³ W/m²
Energy required to arrive = 1.91 × 10⁹ J
Area at the surface = 1 m²
Now,
we know that
Energy = Intensity × Area × Time
or
1.91 × 10⁹ = ( 1.1 × 10³ ) × 1 × Time
or
Time = [ 1.91 × 10⁹ ] ÷ [ 1.1 × 10³ ]
or
Time = 1.736 × 10⁶
