Energy from the Sun arrives at the top of the Earth's atmosphere with an intensity of 1.34 kW/m2. How long does it take (in days) for 1.73 ✕ 109 J to arrive on an area of 9.03 m2?

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.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.
