22. What is the behavior of the current I(t) in this circuit? (A) Imax exp(-t/√LC) (B) Imax exp(-t/LC) (C) Imax sin(t/√LC) (D) Imax, a constant (E) Imax cos(2πt/√LC).

8. Consider a cube of density ρ and horizontal cross-sectional area L² with vertical height L. The cube is floating in a liquid with density ρ_L. At equilibrium a fraction L₀/L of the cube is immersed in the liquid. Now let's push down the cube a little bit and release it. What is the period of the subsequent oscillation? (A) (B)(C)(D)(E) none of the above.
