Alkali metals will always contain one valence electron but the electron configuration will depend on the element
Most likely the second one (sand letting water run through it) because if you are trying to determine how what moves through soil You would want the one the one that can do that:)
Answer:
3.32 m
Explanation:
<u>We have:</u>
<em>f = frequency of the electromagnetics waves = 9.05x10⁷ Hz (frequency of the electromagnetic waves of FM broadcast throughout the world)</em>
<em>c = is the speed of the electromagnetics waves = 3x10⁸ m/s (speed of light)</em>
We can find the wavelength of the electromagnetics waves as follows:
Therefore, the wavelength of a certain FM radio station broadcasts electromagnetic waves is 3.32 m.
I hope it helps you!
