An electric field of 2000 V/m is in the positive x-direction and a magnetic field of 0.1 T is in the positive z-direction. What velocity must a beam of electrons have in order to travel in a straight line? Include both the magnitude and the direction.  

The right portion of a rectangular loop is in a constant magnetic field into the page, while on the left there is no magnetic field, as shown in the figure. If the loop is stationary and a power supply causes a clockwise current in the loop, in which direction will the net force on the loop be?

For all of the remaining problems on this exam, only enter your FINAL answer in the space given. You will submit your work for these problems for partial credit after the exam is over by using the Exam 3 Work assignment in Canvas.

You are given a wire loop and a magnet. Can the following actions cause a current to flow in the wire loop? Shaking the wire loop back and forth while it is near the magnet.  [c1] Shaking the magnet back and forth while it is near the wire.  [c2] Rotating the magnet while it is near the wire.  [c3]  

The current in a wire points due east, and the magnetic force on the wire is upward. If it is known that the magnetic field has zero component in the east/west direction, in which direction does it point?

Explain the physiology of creatine supplementation and how it may, or may not enhance performance.  

2). Because of the buoyancy provided by the ventricles and cerebrospinal fluid, a traumatic blow to one side of the head may cause the brain to “float” back and cause injury when the opposite side of the brain impacts the inside of the skull (a contrecoup injury). Thus, a blow to the frontal lobe may also cause damage to what other lobe?

9). Aqueductal stenosis is a condition where the cerebral aquaduct is blocked. Aqueductal stenosis would prevent the flow of cerebrospinal fluid between                                 .
