The center of mass of a 0.20 kg (non-uniform) meter stick is located at its 46-cm mark. what is the magnitude of the torque (in n⋅m) due to gravity if it is supported at the 29-cm mark? (use g = 9.79 m/s2).

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
