The total momentum of a closed system is observed to be 532 kg•m/s east. The system consists of 13 objects that are observed to be colliding with each other. After 31.9 minute and 9324 collisions, compute the total momentum of the system?
what are the dimensions of the box as measured by an observer moving with a speed of 0.82 c parallel to one of the
A square loop of wire surrounds a solenoid. The side of the square is 0.1 m, while the radius of the solenoid is 0.025 m. The square loop has a resistance of 30 . The solenoid has 500 turns and is 0.3 m long. The current in the solenoid is increasing..
