The dimensions of thermal resistance are :

Options

A. `ML^(2)T^(-2)K^(-2)`
B. `ML^(2)T^(-3)K`
C. `ML^(2)T^(-2)K^(-1)`
D. `M^(-1)L^(-2)T^(3)K`.

Answer

D

Explanation

Dimensional formula for the thermal resistance
`R_(H)=((T_(1)-T_(2)))/((dQ)/(dt))=(K)/("ML"^(2)T^(-3))=[M^(-1)L^(-2)T^(3)K]`
correct choice is (d).
