Two liquids, 1 and 2, are in equilbrium in a u-tube that isopen at both ends. the liquids do not mix, and liquid 1 restson top of liquid 2. how is the density of liquid 1 related tothe density of liquid 2?
a) rho1 is equal to rho2 becausethe liquids are in equilibrium
b) rho1 is greater than rho2
c)rho1 is less than rho2
d) there is not enough info to tell which liquid has greaterdensity

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
