Answer:
Explanation:
Given that:
p = magnitude of charge on a proton =
k = Boltzmann constant =
r = distance between the two carbon nuclei = 1.00 nm =
Since a carbon nucleus contains 6 protons.
So, charge on a carbon nucleus is
We know that the electric potential energy between two charges q and Q separated by a distance r is given by:
So, the potential energy between the two nuclei of carbon is as below:
Hence, the energy stored between two nuclei of carbon is .
Answer:
8.27°
Explanation:
To angle difference will be determined by the difference in the displacement of the springs, produced by the weight of the center of mass of the rod.
by a simple trigonometric relation you obtain that the angle:
hence, the angle between the rod and the horizontal is 8.27°
