Question

Dimensions of pressure are the same as that of
(A) force per unit volume
(B) energy per unit volume
(C) force
(D) energy​

Answer 1

Answer:

formula of pressure is force/area

dimension of pressure [p] = [ML^-1T^-2]

(A) dimension of force per unit volum is [MLT^-2] / [L^3] = [ML^-2T^-2]

(B) dimension of energy per unit volume is [ML^2T^-2] / [L^3] = [ML^-1T^-2]

(C) dimension of force is [MLT^-2]

(D) dimension of energy is [ML^2T^-2]

So correct one is (B) energy per unit volume

Answer 2

Answer:

(A) force per unit volume
