question 101

Multiple Choice

A wire in the shape of an "M" lies in the plane of the paper. It carries a current of 2.0 A, flowing from A to E. It is placed in a uniform magnetic field of 0.85 T in the same plane, directed as shown on the right side of the figure. The figure indicates the dimensions of the wire. Note that AB is parallel to DE and to the baseline from which the magnetic field direction is measured. What are the magnitude and direction of the net force acting on this wire?

Opponent-Process Cells

Specialized cells in the visual system that are used to detect color and are thought to work by encoding differences between the firing rates of pairs of color-sensitive neurons.

Thalamus

The brain’s sensory control center, located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla.

Feature Detectors

Specialized brain cells that identify specific elements or patterns, such as edges, motion, or colors, in the visual environment.

Hubel and Wiesel
