Se dispara un proyectil con una velocidad de 50 m/s con un Angulo de 37° respecto a la horizontal. Calcular después de que tiempo se encontrará a 25m de la superficie por segunda vez

Ihave a density of 1.61g/cm^3 and a mass of 28g. find the missing value

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.)

Me with this and you will be marked brainliest
