which correctly describes the law of conservation of energy? question 6 options: energy can be created or destroyed, but cannot change from one form to another. energy can be created or destroyed, and can change from one form to another. energy cannot be created or destroyed, but can change from one form to another. energy cannot be created or destroyed, and cannot change from one form to another.

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.)
