Each minute earth receives about

2\, \mathrm{cal}

of heat energy per square centimeter from sun. This is called solar constant

\mathrm{S}

. the value of solar constant in S.I. unit is

View answer and explanation

Correct option: B

1.4\, \mathrm{kWm}^{-2}

Option B (

1.4\, \mathrm{kWm}^{-2}

) is correct because it is the solar constant value after converting from

\mathrm{cal} / \mathrm{cm}^2 / \mathrm{min}

to S.I. units.
