The dimensions of stefan 's constant are

Options

A. `[M^(0)LT^(-3)K^(-4)]`
B. `[MLT^(-3)K^(-3)]`
C. `[ML^(2)T^(-3)K^(-4)]`
D. `[ML^(0)T^(-3)K^(-4)]`

Answer

a

Explanation

Stefan's constant is given by `sigma =(E)/(at theta^(4)`
where E is energy radiated A is surface area of body ti is time and `theta` is the absolute temperature
`therefore` Dimensions of stefan 's constant
` =[ML^(2)T^(-2)]/(L^(2)xxTxxK^(4)`
`=[ML^(0)T^(-3)K^(-4)]`
