Uan created a chart to help him study for a test. A 2-column table. The first column labeled X has entries some light is reflected, some light is absorbed, no light passes through. The second column labeled Y has entries some light is reflected, some light is absorbed, some light is reflected, most light passes through.

Which headings best complete the chart?

X: Transparent Objects
Y: Opaque Objects
X: Opaque Objects
Y: Transparent Objects
X: High Frequency Waves
Y: Low Frequency Waves
X: Low Frequency Waves
Y: High Frequency Waves

The answer is B: X: Opaque Objects ; Y: Transparent Objects

Explanation:

The X column describes that the light that shines on that object is reflective, slightly absorptive, and no light passes through it. This describes opaque objects.  Opaque objects are mostly made up of solids, such as rocks and apples.

The Y column describes that the light that shines on it is sometimes refracted, sometimes absorbed, and sometimes reflected, but the light almost always passes through it.  This describes transparent objects. Transparent objects are mostly clear, so you can see through them, such as glass vases and windows.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

more than, less

less than, more
