2 pistons are connected like in the picture. I know the area of the big cylinder is 100 cm2cm2 while the one of the small cylinder is 50 cm2 and that the pistons are tied by a rigid wire. There is air in both cylinders, initially having 27°C and normal pressure. The air in the smaller cylinder is heated, it's temperature increasing by 50°C. How much does the temperature of the air in the large cylinder need to increase so that the 2 pistons don't move ?

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.
