If the Coulomb attractive force between Mg2 and S2- ions at equilibrium is 1.4010 N, calculate: The net energy at minimum separation of ions assuming that the constant of the short range repulsion force is:

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.

a. spokes of a wheel.

as indicated in the question radial contains rad, also found in radius, so the fracture's would span the radius.
