If you disturb a tank of length L and water depth h, the surface will oscillate back and forth at frequency Ω, assumed here to depend also upon water density and the acceleration of gravity g.
(a) Rewrite this as a dimensionless function.
(b) If a tank of water sloshes at 2.0 Hz on earth, how fast would it oscillate on Mars (g ≈ 3.7 m/s2 )?
