It also depends on what we use to make the energy in the power plants. Many use uranium which is non renewable. A better alternative would be wind or solar as it is always around. Hope this helps.
The answers are: T, T, F, T, T, T
To solve this problem, we must be given first the density
of air at 20 degrees Celsius. Looking up online, this is equal to:
density air (20C) = 0.0012041 g/mL
so that the volume is:
volume balloon = 0.57 g / (0.0012041
g/mL)
<span>volume balloon = 473.38 mL</span>

Answer:
The density is
Explanation:
From the question we are told that
the lattice constant is
The density of Copper () is mathematically represented as
Where Z is the number of units in a unit cell and for BCC crystals Z =2
M is the molar mass of copper which same for Copper with a value of
is the Avogadro's constant with a value of
Substituting values
