Two eagles fly directly toward one another, the larger eagle at a speed of 15.0 m/s and the smaller one at a speed of 20.0 m/s. Both eagles screech, the larger emitting a screech of frequency of 3 200 Hz and the smaller one emitting a screech of frequency 3 800 Hz. The speed of sound in the air around the eagles is 330 m/s. What is the frequency of the screech heard by the larger eagle?

Asubmarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. what is the approximate pressure (water plus atmospheric) at this depth? (recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm
