A spring is hung from the ceiling. A 0.410-kg block is then attached to the free end of the spring. When released from rest, the block drops 0.126 m before momentarily coming to rest, after which it moves back upward. Required:

a. What is the spring constant of the spring?

b. Find the angular frequency of the block 's vibrations.

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.
