Question

(a) Density of water in CGS system is g//cm^(3). Convert it into SI unit.
(b) Young's modulus of steel is 2 xx 10^(11) N//m^(2) (SI unit). Convert in into CGS unit (in "dyne"//cm^(2)).

Answer 1

Explanation:

a) g is the cgs unit of mass

cubic.cm is cgs unit of volume

kg is SI unit of mass

cubic meter is the SI unit of volume

$1g = 10 {}^{ - 3} kg$

$1c {}^{3} = 10 {}^{ - 6} m {}^{3}$

density =mass/ volume

$\frac{10 {}^{ - 3} }{10 {}^{ - 6} } kgm {}^{ - 3}$

$10 - 3 - ( - 6)kgm {}^{ - 3}$

by identity

$\frac{a {}^{m} }{a {}^{n } } = a {}^{m - n}$

$1000kgm {}^{ - 3}$
