Question

Evaluate the integral. 19-Even though the actual concentration of oxygen is close to 21 percent (by volume) in the upper stratosphere, explain why, without proper breathing apparatus, you would not be able to survive there? 21- When someone says that" the wind direction today is south," does this mean that the wind is blowing toward the south or from the south? 25- Rank the following storms in size from largest to smallest: hurricane, tornade, middle- latitude cyclonic storm, thunderstorm? 27- How does weather differ from climate? 3cos(x) dx Evaluate the integral.

When someone says that" the wind direction today is south," does this mean that the wind is blowing toward the south or from the south? Rank the following storms in size from largest to smallest: hurricane, tornade, middle- latitude cyclonic storm, thunderstorm? How does weather differ from climate?

Explanation / Answer

Integral answer:

= 3 (sinx) from -pi/2 to pi/2

= 3 [ sin (pi/2) - sin(-pi/2))

= 3(1-(-1))

= 3(2) = 6
