Given two vectors, one 8 units in length the other 3 units in length, explain why the maximum resultant of the two is a single vector 11 units in length and the minimum resultant of the two is a single vector 5 units in length.

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
