39 TUTU plays a cello. On one note, TUTU observes a beat frequency of 12 beats with a 230 Hz tuning fork and a beat frequency of 8 Hz with a tuning fork of 250 Hz. What is the frequency of TUTU's cello? O A. 242 HI O B. 262 Hz O C. 258 Hz O D. 238 Hz O E. 228 Hz 40 TUTU uses an experimental apparatus shown below. By connecting the switch, a current of 2.0 A will flow through the wires from P to Q. If TUTU notes that the magnet produces a field of 2.0 T as shown in the diagram, and the length of wire within the field is 0.02 m, what is true concerning the magnetic force on the wire? switch O A. The wire will be pushed upward, out of the plane of the paper. O B. The wire will have no net force acting on it. O C. The wire will be pushed to the right. O D. The wire will be pushed downward, into the plane of the paper. O E. The wire will be pushed to the left
