Cilindrii din figura de mai jos sunt fixati conform desenului. Pistoanele avand ariile S1=100cm^2 respectiv 50cm^2, sunt uniti cu o tija rigida. In interiorul vaselor se gaseste aer la temperatura 27C si presiunea normala. Aerul din cilindrul mai mic este incalzit cu 50C. Cu cat trebuie modificata temperatura aerului din cilindrul celalalt pentru ca pistoanele sa ramana in aceeasi pozitie?

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.
