! kiki makes a table to compare the particles in a magnesium atom to those in a magnesium ion. she knows that a magnesium ion has an electric field that points away from the ion. what values should she use to complete her table? (the table looks something like this: magnesium atom magnesium ion protons (magnesium atom)12 (and magnesium ion) x neutrons (ma)12 (mi)y electrons (ma) 12 (mi) z a. x: 14 y: 12 z: 12
b. x: 12 y: 12 z: 10
c. x: 12 y: 10 z: 12 x: 12
d. y: 12 z: 14

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
