Answer:
Displacement
Explanation:
The distance between an object and a certain reference point is called displacement. This is not to be confused with distance, which represents the total distance the object has travelled to get a certain point, regardless of how long it is. Displacement always represents the shortest distance (a straight line) between the initial and final points.
Answer:
The Answer is True! I took the test!
Explanation:
Scientists study contrast sensitivity for
sine wave gratings across many different spatial frequencies because:
<span>Patterns of stripes with fuzzy boundaries are common in the real world.</span>
<span>Sine wave is a continuous wave. The smooth repetitive oscillations are
described in Sine waves and stripes are lines or bands.</span>
