A shipwreck salvage company uses a lifting bag to raise a cannon off the sea bed. The bag is inflated with nitrogen to a volume of 5 m3 at the sea bed pressure of 300 kPa. Assuming no change in temperature, what would the volume of the lifting bag be at sea level where the pressure is 100 kPa? Enter your answer as a number ​

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.
