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
