Si Mercurio viaja a 48 km/s, nuestro planeta a 30 km/s y Marte a 24 km/s, y cada uno tarda respectivamente 88 dìas, 365 días y Marte 687 días en dar una vuelta al sol, qué distancia recorren
cada uno de ellos en este período

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.)
