The map shows watersheds with a high potential for soil, nitrogen, and pesticide runoff. If you were in charge of handling the p
Yuri [45]

Answer:

Here are some possible answers:

Why are watersheds in the Midwest more prone to pollution in than other areas in the country?

What are the current flood and pollution control measures in place in high-risk regions?

What are the flaws with the systems used to control pollution in high-risk regions?

What can the officials and scientists in one region learn from those in another region?

What would the effects on residents be if we made changes to current flood and pollution control measures?

Explanation:

When manure or commercial fertilizers enter surface water, the nutrients they release stimulate microorganism growth. The growth and reproduction of microorganisms reduce the dissolved oxygen content of the water body. Without sufficient dissolved oxygen in surface water, fish and other aquatic species suffocate.

A ray of yellow light has a wavelength of about 5.8×10−7 m. Will exposure to yellow light cause electrons to be emitted from ces
Dima020 [189]
Given the wavelength of the yellow light (700 nm. in this case) we can find the frequency 
<span>by dividing the speed of light c by the wavelength w, that is: f = c/w and we know that </span>
<span>c is equal to 2.998 * 10**8 meters per second. </span>
<span>So the frequency f = (2.998 * 10**8) / (7.0 * 10**-7) = 4.283 * 10**14 cycles per sec. </span>
<span>(or Hz.) Since the threshold frequency of Cs is 9.39 * 10**14 Hz, the red light doesn't </span>
<span>have a high enough frequency (or energy) to cause electron emission. </span>
<span>Hope this answers your question.</span>
