the energy received will be 70kw as 1 metre sq in 1 sec gets 1.4 so 10 metre sq in 1 sec will get 14 and in 5 secs will get 70kw

Answer:
7kW/m²
Explanation:
Solar Constant = 1.4 kW/m² (Given)
Solar energy received at area of 1 m² = 1.4 kW/m2
To calculate the solar energy we use over time, and multiply the power consumption by the hours of intended use. For example - an electronic having 20W that is on for 2 hours, will take 20 x 2 = 40WH from the battery. Therefore,
The energy received at an area of 5m² = 5 × 1.4 = 7kW/m²
Thus, the solar energy that will be received at this place per second over an area of 5m² is 7kW/m².
