Consider a parallel-plate capacitor with charge +q on the top plate and –q on the other, and a plate area that is large
relative to the separation distance. Contrast this with a spherical capacitor consisting of two concentric spherical shells,
one smaller than the other, with a charge of +q uniformly distributed on the outer shell and a charge of –q uniformly
distributed on the inner shell. (a) Do the positive and negative charges distribution contribute equally to the electric eld
inside each capacitor? If not, what fraction of the eld comes from the negative distribution? (b) What is the electric eld magnitude outside each capacitor?

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference

In a game of pool, ball a is moving with a velocity v0 of magnitude v0 = 15 ft/s when it strikes balls b and c, which are at rest and aligned as shown. knowing that after the collision the three balls move in the directions indicated and assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the magnitudes of the velocities va, vb, and vc.
