A compass with its needle pointing north sits on a table. We place a straight wire over the compass perpendicular to its needle. We then send a conventional current running west to east through the wire. How does the compass needle respond to the current?
A. The compass needle deflects toward the west.
B. The compass needle deflects toward the east.
C. The compass needle does not do anything.
D. The compass needle turns around to point south.
C. The compass needle does not do anything.

A 2.00-kg object is attached to an ideal massless horizontal spring of spring constant 100.0 N/m and is at rest on a frictionless horizontal table
The spring is aligned along the x-axis and is fixed to a peg in the table. Suddenly this mass is struck by another 2.00-kg object traveling along the x-axis at 3.00 m/s, and the two masses stick together. What are the amplitude and period of the oscillations that result from this collision? A) 0.300 m, 1.26 s B) 0.300 m, 0.889 s C) 0.424 m, 0.889 s D) 0.424 m, 1.26 s E) 0.424 m, 5.00 s
