Explain the difference between vehicular kinematics and occupant kinematics

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.)

If anyonee has done the momentum lab practical in physics can you give me the answers i am s lostt rnn : (

Compare the patterns of the two waves shown in the image. which statement is true about these waves?
