Imagine that scientists of the future launch a large chunk of positively-charged matter into space towards the sun. After a long time, researchers notice that the chunk of matter has gone into orbit around the sun instead of flying past the sun and continuing on its way. Which statement best explains this phenomenon?

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.)
