Learning goal: to introduce the idea of physical dimensions and to learn how to find them. physical quantities are generally not purely numerical: they have a particular dimension or combination of dimensions associated with them. thus, your height is not 74, but rather 74 inches, often expressed as 6 feet 2 inches. although feet and inches are different units they have the same dimension--length. find the dimensions [v] of volume. find the dimensions [v] of speed. express your answer as powers of length ( l), mass ( m), and time ( t)

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.)
