The graph shows a plot of an object's velocity versus time for 15 seconds. Is the acceleration of the object constant or changing? How do you know? What does this tell you about the net force on the object? Plzzz help

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.)
