Pitch and Amplitude of a wave #sound #energy #physics

Two sound waves travel in the same direction in a medium. The amplitude of each wave is A and the phase difference between the two waves is 120^(@) . The resultant amplitude will be

A muscial instrument P produces sound waves of frequency n and amplitude A. Another musical instrument Q produces sound waves of frequency (n)/(4) . The waves produced by P and Q have equal energies. If the amplitude of waves produced by p is A_(P) , then the amplitude of waves produced by Q will be
