A system of millions or billions of stars together with gas and dust, held together by gravitational attraction
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>
Answer:
A. the rate that something moves and is calculated by taking distance divided by time
D) because the refrigerator was much heavier than the other objects
Since density would be D=M/V, we’d have to literally divide 20 by 4.
20 divided by 4 is 5, so the density of the mineral sample is 5 grams.
Please correct me if I am wrong!
