Constants periodic table an ideal gas with y = 1.4 occupies 3.5 l at 300 k and 130 kpa pressure and is heated at constant volume until its pressure has doubled. it's then compressed adiabatically until its volume is one-fourth its original value, then cooled at constant volume to 300 k, and finally allowed to expand isothermally to its original state.

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.
