Solar constant of the sun is the energy received by earth per minute per `cm^(2)`. Its dimensions will be :

Options

A. `[ML^(2)T^(-3)]`
B. `[ML^(0)T^(-3)]`
C. `[ML^(2)T^(-1)]`
D. `[ML^(0)T^(-1)]`

Answer

B

Explanation

Solar constant `sigma=("Energy")/("area xx time")`
`:.sigma=(ML^(2)T^(-2))/(L^(2)xxT^(1))`
`=ML^(0)T^(-3)`
Hence `(b)` is the right choice.
