You are standing at the midpoint between two speakers, a distance d away from each. the speakers are playing the exact same sound of frequency 170 hz in phase with each other. describe what happens when you walk 1.5 m directly toward one of the speakers. assume the speed of sound is 340 m/s. also assume you can't hear any sounds except those produced by the speakers.

Consider an ordinary, helium-filled party balloon with a volume of 2.2 ft3. the lifting force on the balloon due to the outside air is the net resultant of the pressure distribution exerted on the exterior surface of the balloon. using this fact, we can derive archimedes’ principle, namely that the upward force on the balloon is equal to the weight of the air displaced by the balloon. assuming that the balloon is at sea level, where the air density is 0.002377 slug/ft3, calculate the maximum weight that can be lifted by the balloon. note: the molecular weight of air is 28.8 and that of helium is 4.
