Answer:
5.08cm³
Explanation:
Given parameters
The larger cube has twice the mass of the smaller cube
Mass of smaller cube = 20g
Mass of the larger cube = 2 x 20 = 40g
Density of the smaller cube = 7.87g/cm³
Unknown:
Volume of the larger cube = ?
Solution:
Density is the mass per unit volume of substance. For all samples of a substance, the density value is the same.
So, the density of the small and large iron is the same
Density =
Volume =
So;
Volume of larger cube = = 5.08cm³
The answer would be it will be longer than the 656.3 nm. The reduced mass of positronium is less than hydrogen so the photon energy will be a reduced amount of for positronium than for hydrogen. So this will mean that the wavelength will be lengthier.
The answer is: " 5 g / cm³ " .

Explanation:
____________________________________________
Density = mass divided by volume ; or: "D = m / V " ;
____________________________________________
and is expressed as: "mass per unit volume" ;
The mass, "m", is expressed in units of "g" (grams) ; and
the volume, "V" is expressed in units of "cm³ " or "mL" ; ("cm³ ", in this case);
{Note the exact conversion: " 1 cm³ = 1 mL " .} .
_____________________________________________________
So, if: the mass, "m = 100 g" {given} ;
and the volume, " V = 20 cm³ " {given} ;
_______________________________
Plug these values into the formula/equation to solve for the density, "D" ;
________________________________________________
D = m / V = (100 g) / (20 cm³)
= (100 ÷ 20) g / cm³ = 5 g /cm³ .
____________________________________________
The answer is: " 5 g / cm³ " .
