Helloo...I have a doubt regarding GRAPHICAL REPRESENTATION OF MOTION (GRADE 9) Can you please tell me how many types of motions are there in V-T and S-T graphs (for example uniform accelerated motion...there's supposed to be 7 ..but I don't know them;) Please do let me know at the earliest cause I have test tomorrow CAN YOU ALSO TELL ME THE TYPE OF MOTION FOR THESE GRAPHS?? pls quickkk

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.)
