A flutist assembles her flute in a room where the speed of sound is 342 m/sm/s . When she plays the note A, it is in perfect tune with a 440 Hz Hz tuning fork. After a few minutes, the air inside her flute has warmed to where the speed of sound is 346 m/sm/s .1.How many beats per second will she hear if she now plays the note A as the tuning fork is sounded?
2.How far does she need to extend the "tuning joint" of her flute to be in tune with the tuning fork?

Need asap ! what is the relationship between atmospheric pressure and the density of gas particles in an area of increasing pressure? (2 points) as air pressure in an area increases, the density of the gas particles in that area decreases. as air pressure in an area increases, the density of the gas particles in that area increases. as air pressure in an area increases, the density of the gas particles in that area remains constant. as air pressure in an area increases, the density of the gas particles in that area increases and decreases in an alternating pattern. 3. which of the following correctly describes a way in which earth's atmosphere interacts with the geosphere?
