A spring is attached to the ceiling and pulled 19 cm down from equilibrium and released. The amplitude decreases by 18% each second. The spring oscillates 14 times each second. Find an equation for the distance, D the end of the spring is below equilibrium in terms of seconds, t.

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.
