Answer» Joule is the unit for energy Dimension Formula for Joule is [M¹L²T⁻²] Let n1(joule)=n2(erg) n1(M₁¹L₁²T₁⁻²]=n2[M₂¹L₂²T₂⁻²] n2=n1(M₁¹L₁²T₁⁻²]/M₂¹L₂²T₂⁻²] =n1x(M1/M2)¹x(L1/L2)²x(T1/T2)⁻² =1x(1kg/gm)¹x(1m/1cm)²x(1s/1s)⁻² =1x(1000g/gm)x(100cm/1cm)²x(1s/1s)⁻² =10⁷Therefore n1(joule)=n2(erg)∴1 Joule=10⁷erg |
