WILL MARK BRAINLIEST A peregrine falcon dives at a pigeon. The
falcon starts downward from rest and falls
with free-fall acceleration.
If the pigeon is 77.2 m below the initial
position of the falcon, how long does the falcon
take to reach the pigeon? Assume that the
pigeon remains at rest. The acceleration of
gravity is 9.8 m/s.
Answer in units of s.

Ajet plane has a sound level of 120 db at a distance of 60 m. what is the q23. sound level at a distance of 6.0 km? (60)2 (6000)? om solution 80db db, hint: 16x assume ultrasound waves travel through the body of an animal at 1540 q24. m/s. if a 30,000 hz signal were reflected off a portion of a heart which was moving toward the source at 3 m/s, what frequency signal would return to the stationary source? solution 30.117hz
