It is estimated that per minute each `cm^(2)` of earth receives about 2 calorie of heat energy from the sun. This constant is called solar constant S. Express solar constant in SI units.

Text Solution

Verified by Experts

The correct Answer is:
1.4
`S=(2"cals")/("min.cm"^2)=(2xx4.2 "joule")/(60sxx10^(-4)m^2)`
`1.4 xx10^(3)W//m^2`
