A ball starts from rest and accelerates at 0.505 m/s2 while moving down an inclined plane 9.10 m long. When it reaches the bottom, the ball rolls up another plane, where, after moving 13.3 m, it comes to rest. What is the speed of the ball at the bottom of the first plane

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

The energy produced as a result of this flow of electrons from atom to atom is called

Two balls, each with a mass of 0.5 kg, collide on a pool table. is the law of conservation of momentum satisfied in the collision? explain why or why not
