When many atoms are split in a chain reaction, a large explosion occurs. this is an example of what type of energy conservation

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

How is sound energy produced a. vibrating objects b. objects being heated c. temperature differences d. stationary objects
