Answer:
Compound Basics
Explanation:
Molecule is the general term used to describe any atoms that are connected by chemical bonds. ... Hydrogen gas (H2) is a molecule, but not a compound because it is made of only one element. Water (H2O) can be called a molecule or a compound because it is made of hydrogen (H) and oxygen (O) atoms.
Potencial Energy=hma
Where
Potencial Energy =E= 54.9J
h=?
m=8kg
a=9.8m/s^2
You need to know that 1 J=1(kgm^2)/s^2
Isolate h=E/(ma)
h=(54.9)/(8*9.8)
We don't have much to go on.
The dimensions of D depend on the dimensions of N, n, and x, and we don't know what any of those stand for.
It might help if we had ever heard of 'diffastion', but we're striking out there too.
