A resistor dissipates 1.95 W when the rms voltage of the emf is 10.5 V . Part A At what rms voltage will the resistor dissipate 10.5 W

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
