If the space shuttle Endeavor ran out of fuel, while in space, it would - no longer accelerate but maintain its velocity because space has no friction.
-accelerate for awhile then slow down.
-come to a stop.
-work normally because fuel is not necessary for acceleration in space.

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.
