Ksivusya [100]

F(2)+g(4)
evaluate them seperately
f(2)=2+2=4

g(4)=10(4)-4
g(4)=40-4
g(4)=36

f(2)+g(4)=4+36=40

a laboratory, you determine that the density of a certain solid is 5.23×10−6kg/mm3. Convert this density into kilograms per cubi

Vedmedyk [2.9K]

Answer:

$5.23\times 10^{-6}\ kg/mm^3=5230\ kg/m^3$

Step-by-step explanation:

Given : The density of a certain solid is $5.23\times 10^{-6}$ kg/mm³.

To find : Convert this density into kilograms per cubic meter ?

Solution :

We know that,

$1\ m^3=10^9\ mm^3$

or $10^9\ mm^3=1\ m^3$

So, $1 mm^3=\frac{1}{10^9}\ m^3$

$1 mm^3=10^{-9}\ m^3$

Converting $5.23\times 10^{-6}$ kg/mm³ into kg/m³,

$5.23\times 10^{-6}\ kg/mm^3=\frac{5.23\times 10^{-6}}{10^{-9}}\ kg/m^3$

$5.23\times 10^{-6}\ kg/mm^3=5.23\times 10^{-6+9}\ kg/m^3$

$5.23\times 10^{-6}\ kg/mm^3=5.23\times 10^{3}\ kg/m^3$

$5.23\times 10^{-6}\ kg/mm^3=5230\ kg/m^3$

Therefore, $5.23\times 10^{-6}\ kg/mm^3=5230\ kg/m^3$
