(i) The density of a meterial is `0.8 g cm^(-3).` Its value in SI units is …… .
(ii) The Young's modulus of steel is `1.9xx10^(11) N//m^2.` Its value in CGS units is …… .

Explanation

(i) `rho = 0.8 g cm^(-3)`
`=(0.8g)/((cm)^3) = (0.8xx10^(-3)kg)/((10^(-2)m)^3) = 0.8xx1-^3kg//m^3`
(ii) `Y = 1.9xx10^(11) N//m^2 =(1.9xx10^(11)xx10^5 dy"ne")/((10^2 cm))`
`=1.9xx10^(12) dy"ne"//cm^2`
