Given :
Intensity, I = 1.34 kW/m².
Area, A = 3.28 m².
To Find :
Time taken to arrive.
Solution :
Power is given by :
P = I × A
P = 1.34 × 3.28 × 1000 W
P = 4395.2 W
Also, power is given by :
P = E/t
t = E/P
t = 1.73 × 10⁹ J/4395.2 W
t = 393611 s
Converting this time in second to days, we get :
t = 393611/( 24×60×60) days
t = 4.55 days.
Hence, this is the required solution.
