Lead has a density of 11.4 g/cm^3. What is the density in kilograms per cubic meter?

Vikentia [17]

The density in kg/m³ = 1.14 x 10⁴

<h3>Further explanation </h3>

Density is a quantity derived from the mass and volume

Density is the ratio of mass per unit volume

With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of density

The unit of density can be expressed in g/cm³ or kg/m³

Density formula:

$\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}$

ρ = density , g/cm³ or kg/m³

m = mass , g or kg

v = volume , cm³ or m³

A density of Lead : ρ = 11.4 g/cm³

the density in kg/m³ :

$\tt 11.4~\dfrac{g}{cm^3}\times \dfrac{kg}{10^3~g}\times \dfrac{cm^3}{10^{-6}~m^3}=\boxed{\bold{1.14\times 10^4~\dfrac{kg}{m^3}}}$

HELP ME PLEASE!!!!!!!!<br><br><br><br> Explain how magnetic force works on a magnet

RSB [31]

A magnet creates an invisible area of magnetism all around it called a magnetic field. The north pole of a magnet points roughly toward Earth's north pole and vice-versa. That's because Earth itself contains magnetic materials and behaves like a gigantic magnet

An "adaptation." It's the natural way that birds of flight adapt to their needs or environment which makes them more efficient. :)
