The conductor is connected to a 12V voltage, with a current of 500mA flowing through the conductor. During what time will the electricity work be 100J?

F = force
l = length
P = power
t = time

U = potential energy
R = resistance
E = energy

Which situation will produce the greatest change of momentum

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.)
