Asphere completely submerged in water is tethered to the bottom with a string. the tension in the string is one-fourth the weight of the sphere.

what is the density of the sphere?

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.)

The energy produced as a result of this flow of electrons from atom to atom is called
