Generate a spreadsheet that allows the user to input values of a, b, and n (equation 2.17) and then does the following:
(a) plots on a graph of potential energy versus interatomic separation for two atoms/ions, curves for attractive (ea), repulsive (er),and net (en)
energies.
(b) determines the equilibrium spacing (r0) and
the bonding energy (e0).

What is the most useful equation for electric power?

What is the measure of a change in an objects velocity?

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
