An electric current is a constant flow of electric charges along a path. What are some advantages of using electric current instead of individual charges to discuss the movement of charges? Relate your explanation to another situation where discussing rates of movement would be more useful than discussing the movement of individual items.

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 released by a nuclear fusion reaction is produced when
