Question

Write the Dimensional formulaes for power and desity. please help me fast​

Answer 1

Answer:

Therefpre, the dimensional formula of power, P=[MLT−2]×[LT−1]=[ML2T−3]

Answer 2

Answer:

Dimensional Formula of DensityThe dimensional formula of density is given by,[M1 L-3 T0]Where,

• Dimensional Formula of DensityThe dimensional formula of density is given by,[M1 L-3 T0]Where,M = Mass
• L = Length
• L = LengthT = Time

L = LengthT = TimeDerivationDensity (ρ) = Mass × Volume-1 . . . . . (1)The dimensional formula of volume = [M0 L3 T0] . . . . (2)And, the dimensional formula of mass = [M1 L0 T0] . . . . (3)On substituting equation (2) and (3) in equation (1) we get,Density = Mass × Volume-1Or, (ρ) = [M1 L0 T0] × [M0 L3 T0]-1 = [M1 L-3 T0]
