Correct Answer : D
Explanation :
Explanation :
The value of Solar constant = 1.4kW/m2 = 1.4 kJ/s/m2 .
The Solar energy received in 1 hour on 1 m2 of Area = Value of Solar Constant x Time in Seconds
Area = 1 m2.
Solar energy received on 1 m2 area in 1 second = 1.4 kJ (Solar Constant)
Total energy received in 1 hour = 1.4 kJ x (60 x 60)
Because,
1 hour = 3600 seconds.
Therefore,
Total energy received in 1 hour = 1.4 kJ x (3600) = 5040 kJ
