Aforce f s applied to an object of mass m1 produces an acceleration of 3.00 m/s2. the same force applied to a second object of mass m2 produces an acceleration of 1.00 m/s2. (a) what is the value of the ratio m1/m2? (b) if m1 and m2 are combined into one object, find its acceleration under the action of the force f s .

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
