Two forces are acting on a 0.250 kg hockey puck as it slides along the ice. the first force has a magnitude of 0.320 n and points 15.0° north of east. the second force has a magnitude of 0.600 n and points 55.0 ° north of east. if these are the only two forces acting on the puck, what will be the magnitude and direction of the puck's acceleration? enter the direction as an angle measured in degrees counterclockwise from due east.

Two loudspeakers, 5.5 m apart and facing each other, play identical sounds of the same frequency. you stand halfway between them, where there is a maximum of sound intensity. moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.33 m . assume the speed of sound is 340 m/s.part a) what is the frequency of the sound? part b) if the frequency is then increased while you remain 0.21 m from the center, what is the first frequency for which that location will be a maximum of sound intensity? express your answer to two significant figures and include the appropriate units.
