Aball is thrown at a 60.0° angle above the horizontal across level ground. it is released from a
height of 2.00 m above the ground with a speed of 16.0 m/s. how long does the ball remain in the
air before striking the ground?

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
