An observer measures the length (L), width (w), and height (h) of a box while stationary relative to the box. The observer then travels at near light speeds parallel to the length (L) of the box. If the observer measures the width (w) of the box while moving, the measured value will now be:
a. equal to w.
b. less than w.
c. greater than w.
d. information is needed. You need to know the density of the box.
