Suppose the conducting wire (with resistance r) was replace with one of the same material but has its dimension doubled (the length and the radius having twice their original value. what is the new resistance in comparison to the previous resistance?

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
