Answer:

D. Visible Light

Explanation:

D is the right answer because visible light is perceived by humans as color and the rest aren't visible at all. For example, if you broke a bone and have to have an X-ray done, you can't see the x-rays. When you are heating something in the microwave, you can't see the waves. And when you are listening to the radio in the car, you also can't see the waves.

If 211 mL of water is added to 5.00 mL of 3.24 M NaCl solution,
Softa [21]

Answer:

0.075M

Explanation:

-The concentration of a solution is defined as the mass of the solute divided by the volume of the solution:

Concentration=\frac{Mass \ Solute}{Volume \ of \ Solution}

-We the solve the molarity problem as follows:

M_1V_1=M_2V_2\\\\V_2=V_1+211=211+5=216mL\\\\\therefore M_2=\frac{M_1V_1}{V_2}\\\\=\frac{3.24\times 5}{216}\\\\\\=0.075\ M

Hence, the concentration of the dilute solution is 0.075M

Gestalt psychology focuses on _____.
jok3333 [9.3K]

Answer:

the brain's ability to memorize information

Explanation:

Gestalt psychology provides a holistic perception to how the brain tends to deal with information it picks. The belief is that the whole is greater than the individual parts. Gestalt is a German word which means whole.

Psychologists that subscribes to this school of thought believes that the brain generally relates with events by creating a complete perceived view of such. For example, christmas lights are pictured as moving because its easier for the brain to relate with such rythm in that way. This helps the brain memorize a piece better than looking at individual relationship between the parts.
