When flying from warmer than standard air towards colder than standard air, with the aircraft’s pressure altimeter indicating a constant altitude, is the aircraft’s ACTUAL altitude changing? If so, is it gaining or losing altitude? Explain your answer. (Assume no corrections are made to the altimeter during the flight.)

Looking at this barometer, is the air pressure high or low? what type of weather would you expect? high, bad low, bad high, good low, good

What property of an object determines its inertia?

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.
