Your lungs are the main organ that helps your body breath.

<span>The lungs are the main organ of the respiratory system, which carries oxygen through the body by means of red blood cells and picks up carbon dioxide, a waste gas, to expel from the body when an organism exhales. The trachea filters the inhaled air and branches into the bronchi, where the air tubes carry air directly into the lungs. The diaphragm is the main muscle of the respiratory system, contracting to increase the volume of the lungs and carry air into the body and expanding to force air out of the lungs.</span>

To which period does an element belong if it has its 3d orbitals filled
swat32

fourth period

The third period is similar to the second, except the 3s and 3p sublevels are being filled. Because the 3d sublevel does not fill until after the 4s sublevel, the fourth period contains 18 elements, due to the 10 additional electrons that can be accommodated by the 3d orbitals.

Answer:

D. As white light passes through a prism , it bends and separates into different colors

Explanation:

When light enters a prism, it experiences a phenomenon called 'refraction'.

Refraction occurs when light crosses the interface between two mediums with different optical density; when this happens, the light bends and also changes speed.

The angle at which the ray of light is refracted into the second medium depends on the optical density of the two mediums, but also on the wavelength of the light.

In particular, longer wavelengths (red color) are refracted the least, while shorter wavelengths (violet color) are refracted the most.

As a result, when white light (consisting of all the colors of visible light) enters into a prism, they different wavelengths are separated: therefore, white light separates into different colors.

So, the correct answer is

D. As white light passes through a prism , it bends and separates into different colors
