Best answer

(a) Resistivily

Explanation:

Resistivity = ρ = (RA / L)

R = (V/I) & V = (W/Q) = (W / It)

[as V = (work / charge) = [(work) / (current × time)]

 Hence V = ([M1L2T–2] / [A1T]) = [M1L2T–3A–1]

Hence R = ([M1L2T–3A–1] / [A1]) = [M1L2T–3A–2]

  Now ρ = (RA / L)

    = ({[M1L2T–3A–2] [L2]} / [L])

  = [M1L3T–3A–2]
