Using a circuit of 24 ohms, 10 ohm, and 38 ohms if the current reading in the ammeter is 0.4 A, what is the voltage drop across the 38 ohms resistor?

Which statement best describes the superposition principle? a.) if two in-phase waves arrive simultaneously at a point, their amplitudes add up b.) if two out-of-phase waves arrive simultaneously at a point, their amplitudes add up c.) if two in-phase waves arrive at a point one after another, their amplitudes add up d.) if two out-of-phase waves arrive at a point one after another, their amplitudes adds up
