Write an expression for the output voltage of an AC source that has an amplitude of 17 V and a frequency of 160 Hz. (Use the following as necessary: t. Assume V is in volts and t is in seconds. Assume V = 0 and dV/dta = 0 when t = 0.) V = 27 sin ( 270πt)

(**i would really appreciate if this was answered soon** ) which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?

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.)

Give an example in which the electrical energy changes to light energy
